No. 2).

[0003]

The sublimation type thermal transfer recording is as follows.
Although image quality close to that of photographs can be obtained, in order to obtain this excellent image quality and recording density, a special image receptor with a dyeing layer on which dye is dyed is required. Cannot obtain such image quality and recording density.
Further, in the case of an image receiving body in which a dyeing layer is provided on plain paper in advance and recording is performed as in the above-described conventional example, the image receiving body is not uniform due to the non-uniformity of the fiber density of the cellulose fibers unique to the plain paper and the thickness unevenness. And the dot reproducibility is significantly reduced. Also, the method of forming an image on an arbitrary substrate via an adhesive layer such as a tack sheet is difficult to handle when the characteristic peculiar to sticking to anything unique to the adhesive sheet is mechanically treated. And a special sheet such as a tack sheet is required.

SUMMARY OF THE INVENTION In view of the above problems, the present invention makes it possible to perform high-quality image recording on any substrate such as plain paper for sublimation type thermal transfer recording, and has an extra problem in handling such as tack sheets. An object of the present invention is to provide a recording method and a transfer body which do not require a sheet.

[0005]

In order to solve the above-mentioned problems, a recording method according to the present invention comprises a combination of a transfer member having a color material layer and a dyeing layer at different positions on a substrate, and an image receiving member. In, first, the transfer material is overlapped so that the color material layer surface and the dyeing layer surface overlap each other, a recording image is formed on the dyeing layer by the recording head from the substrate side of the transfer body, and then the dyeing layer is heated and An image is formed on the image receiving member by transferring the image onto the image receiving member by pressure and / or the dyeing layer on the image receiving member is further subjected to heat and / or pressure on the image receiving member having the image obtained by the recording method.

According to the recording method of the present invention, in a transfer body having both a color material layer and a dyeing layer, an image is formed on the transfer body and then a recorded image portion and the like are transferred to an image receiving body. No extra sheets are required in addition to the body and the receiver, and no special paper such as coated paper is required as the receiver. Can be recorded. or,
As the transfer body, a polymer film or the like having excellent uniformity in density and thickness can be arbitrarily selected as a base material, and excellent high image quality can be obtained since image recording is performed on the transfer body.

In the present invention, when a polyvinyl butyral having a butyralization degree of 50 mol% or more is used for a binder or a dyeing layer of a color material layer as a transfer member, the dyeing material is particularly suitable for the color material layer. It has been experimentally found that the heat-sealing prevention properties between layers are excellent. This is because polyvinyl butyral has an acetal structure having a large steric structure and a long non-polar group such as a propyl group at the terminal of the acetal structure, thereby contributing to adhesiveness. It is considered that the steric effect in terms of molecular structure, which is more likely to control the surface than the hydroxyl group in the molecule, which is considered to have contributed particularly to the heat-sealing prevention property. This effect is particularly remarkable as the degree of butyralization is larger, and particularly at 50 mol% or more. When polyvinyl butyral having a butyralization degree of 50 mol% or more is used for the binder or the dyeing layer of the color material layer, the heat-sealing prevention property is particularly excellent, so Even if a dyeing layer with low adhesion to the base material is provided, there is no problem that the dyeing layer is transferred to the color material layer side during thermal transfer recording, and the dyeing layer is then easily transferred onto the image receptor. It is possible to do.

When formed using at least one selected from acrylate copolymer resin, saturated polyester resin, polyester urethane, polyvinyl acetal, polycarbonate or cellulose resin, Fluorine-containing moisture-curable resin or siloxane-containing moisture-curable resin is particularly excellent in thermal fusion even when a heat-resistant dyeing layer such as acrylonitrile-styrene copolymer resin is provided directly on the substrate. Due to the prevention characteristics, there is no problem that the dyeing layer is transferred to the color material layer side during thermal transfer recording, and high recording sensitivity is obtained.

The structure of various transfer bodies, such as having a color material layer and a laminate at different positions on the substrate, or having a color material layer on one side of the substrate and at least a dyeing layer on the other side, is as follows. And a transfer member configuration particularly useful for the recording method of the present invention.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The first aspect of the thermal transfer recording method of the present invention is to use a transfer member having a color material layer and a dyeing layer on a base material and an image receiving member. The thermal transfer image is recorded on the dyeing layer by the combination of the above, and then the dyeing layer is transferred to the image receiving body.

In the first recording method, the transfer member having a color material layer and a dyeing layer on a base material has a structure in which a color material layer and a laminate are provided on a base material, and the laminate is provided with a release layer. The sequential laminate with the dyeing layer or the laminate is a sequential laminate of the polymer material layer and the dyeing layer or the laminate is a sequential laminate of the release layer, the polymer material layer, and the dyeing layer. It also includes a transcript. However, when the dyeing layer is a laminate, the dye transfer layer or the dyeing layer and the polymer material layer are transferred to an image receiving body after recording a thermal transfer image on the laminate. For example, a transfer body having a color material layer and a laminate at different positions on a base material, and the laminate is formed of a sequential laminate of a release layer, a polymer material layer, and a dyeing layer is the laminate. Is transferred to an image receptor to form an image on the image receptor.

A second aspect of the thermal transfer recording method according to the present invention is that each image receiving body having a transferred image obtained by the first recording method is
Further, the dyeing layer (or the polymer material layer and the dyeing layer) on the image receiving body is fixed to the image receiving body by heat and / or pressure.

A third aspect of the thermal transfer recording method of the present invention is that, similar to the first recording method, after a thermal transfer image is recorded on a dyeing layer (or laminate), a transfer body having the dyeing layer (or laminate) is formed. The part and the image receiving body are integrated.

FIG. 1 is a schematic view showing the principle of a recording method as an embodiment of the recording method of the present invention, and FIG. 2 is a recording portion for forming an image on a dyed layer as an embodiment of the recording method of the present invention. FIG. 3 and FIG. 4 are schematic partial views schematically showing a portion for transferring and fixing a dyeing layer to an image receiving body as each embodiment of the recording method according to the present invention. FIG. 3 is a partial schematic view showing in principle a portion for transferring and fixing a laminate on an image receiving body as one embodiment of the recording method of the present invention;
FIG. 6 is a partial schematic view showing in principle a portion for integrating a transfer body and an image receiving body as one embodiment of the recording method of the present invention. FIGS. 1 to 6 show schematic or partial schematic diagrams of each recording principle. Naturally, the structure and traveling system of each transfer member and image receiving member, and the positions of the recording head, platen and each roll. The present invention is not limited to the figures shown in FIGS.

First, the first recording method of the present invention will be described. In FIG. 1, a transfer member having a configuration in which a color material layer and a dyeing layer are provided on a substrate as a transfer member is shown as an example. The transfer body 1 has a dyeing layer 13 and a coloring material layer 1 on a base material 12.
4, a coloring material layer and a coloring material layer are formed alternately (surface-sequential) such as a coloring material layer 15 and a coloring material layer 16.
The image formation on the dyeing layer 17 is performed by overlapping with any color material layer, for example, the color material layer 14 on the same surface of the transfer body. Since the color material layer 14 and the dyeing layer 17 are formed on the same surface of a continuous base material, the color material layer and the dyeing layer must be overlapped with each other to overlap the color material layer surface and the dyeing layer surface. The transfer member is bent with the surface on which the is formed inward. In FIG. 1, a transfer body 1 is provided between a recording head 3 and a platen 4, a roll 10, a speed setting roll 7, and a vertically movable roll.
After passing through the roll 9, the speed setting roll 8, and the roll 11, respectively, and returning between the recording head 3 and the platen 4, the color material layer 14 and the dyeing layer 17 are disposed between the recording head 3 and the platen 4. Are sandwiched so as to overlap. As described above, in a state where the transfer bodies 1 are sandwiched between the recording head and the platen under appropriate pressure, the dye of the color material layer is sublimated or diffusion-transferred to the dyeing layer by the recording head to form an image on the dyeing layer. It is formed. The position of the recording head is not limited to the base material side of the color material layer but may be on the base material side of the dyeing layer. The speed setting roll 7 and the speed setting roll 8 are rolls for setting the traveling speed or position of the transfer body 1 to a target speed or position, respectively. The vertically movable roll 9 is a roll for adjusting the tension of the transfer body 1. The traveling direction of the transfer body is not particularly limited. For example, between the recording head and the platen at the time of recording, the transfer member portion having the color material layer and the transfer member portion having the dyeing layer respectively run in the same direction or run in opposite directions or run at different relative speeds. The traveling mode is not particularly limited. When there are a plurality of color material layers having different color materials such as a cyan color material layer, a magenta color material layer, and a yellow color material layer on the base material, the transfer member portion having the second color material layer is replaced with one. The color can be recorded by moving it onto the dyed layer on which the color is recorded. Hereinafter, the third color or more can be recorded in the same manner. When a plurality of recording heads are used, each color can be shared and recorded by each head, so that the recording speed is improved. The recording head is not particularly limited as long as it can form an image on the dyed layer by sublimating or diffusing the color material of the color material layer of the transfer body using, for example, a thermal head, an energizing head, an optical head, or the like. Not something. Since recording is performed between the recording head 3 and the platen 4, the arrangement of the coloring material layer and the dyeing layer of the transfer body or the running system of the recording apparatus is performed so that the color material layer and the dyeing layer just overlap between the recording head and the platen. Is desirably configured.

The transfer member portion having the dyed layer on which an image is formed as described above is combined with an image receiving member 2 such as plain paper in FIG. 1 to form a dyed layer on which an image of the transfer member is formed. 1
Heat and / or pressure are applied so that the eight faces and the two image receiving faces face each other (in FIG. 1, the heat passes between the heating roll 5 and the heating roll 6 which are appropriately pressed). The dyed layer 18 on which the image has been formed is the transfer body 1
Is transferred onto the image receiving body 2 away from the base material 12 of the
An image is formed thereon. Used color material layer 19 of transfer body
For example, when the color material layer 19 passes between the heating roll 5 and the heating roll 6, the heating roll 5 and the heating roll 6 pass through. The roller 6 is preferably separated from the heating roller by a running system in which at least the surface of the coloring material layer 19 is not in contact with the heating roller. The treatment of the transfer body having the used color material layer 19 of the transfer body is not limited to the method described above. Of course, the recording head, platen, heating roll 5 or heating roll 6
Can be configured so that the position thereof can be changed according to the moving state of the transfer body. Also, in FIG.
Although the running system between the rollers 6 is omitted, various rolls such as pinch rolls may be interposed.

The method of applying heat and / or pressure is:
For example, it can be obtained by passing the image receiving body and the transfer body between media whose at least one of them is heated and under appropriate pressing, or between media having high pressing force. Alternatively, a light source having large radiant heat can be used. In FIG. 1, two heating rolls (5 and 6, respectively) are used as an example of the medium. As a roll or a heating roll, for example, rubber (rubber-coated) rolls such as silicone rubber, fluorine rubber, urethane rubber, etc., plastic rolls, metal rolls
And Teflon control are useful. Heat and /
Alternatively, the method of applying pressure is not particularly limited as long as it has an effect of transferring the dyeing layer (or the high molecular substance layer and the dyeing layer) of the transfer body onto the image receiving body. This is the case where two rolls are used under appropriate pressure (eg, spring or air pressure). For example, there is a combination of an elastic roll such as silicone rubber and a metal roll, or a combination of an elastic roll and an elastic roll. Further, by using a thermal recording head such as a thermal head or a current-carrying head as one of the media, only the necessary portion of the transfer-receiving layer (for example, only the area containing the recorded image of the dyed layer, (Only the necessary parts of the material layer and the dyeing layer) can be transferred onto the image receiving body. The heating temperature is not particularly limited, but usually,
It is used in the range from room temperature to 300 ° C. Although the pressure is not particularly limited, it is usually used at 10 ⁸ Pa or less.

The transfer of the dyeing layer 18 onto the image receiving member 2 may be performed by fusing the dyeing layer 18 to the surface of the image receiving member such as paper or filling or softening bonding between paper fibers by heat and / or pressure. It is performed by The transfer is performed, for example, by peeling the base material 12 of the transfer body from the dyeing layer 18 immediately after between the two heating rolls (5 and 6 respectively) in FIG. 1, or by heating as shown in FIG. Any cooling after the passage of time after passing between the rolls (for example, after further passing between the rolls 40 and 41) may be used. In FIG. 1, for example, when an image is formed on a dyeing layer using a plurality of color material layers having different color materials such as a cyan color material layer, a magenta color material layer, and a yellow color material layer, one image is formed. A color image may be formed by a plurality of color material layers on the dyeing layer, or an image of each color may be formed on each dye layer corresponding to the color material layer of each color. In particular, in the latter case, the transfer to the image receiving member 2 is carried out by superimposing the dyeing layers of the respective colors on the image receiving member 2 so that a plurality of colors or full color images can be formed on the image receiving member.
Image can be formed. When the transfer body has a coloring material layer, a dyeing layer, and other layers (for example, a polymer material layer, an ultraviolet absorber layer, or an overcoat layer) on a substrate, an image is not formed. A dye layer on which no image is formed on the formed dye layer, an ultraviolet absorber layer on the dye layer on which the image is formed, or a polymer material layer on the dye layer on which a monochrome image is formed. Various layers can be superimposed and transferred, such as further superimposing two layers of repeating units. When the transfer body has a pigment ink layer as another layer, the pigment ink layer is recorded on a base material or a dyeing layer of the transfer body by a recording head and then transferred onto the image receiver or transferred to the image receiver. It can be overlaid and transferred onto the transfer dyeing layer, and a sublimation type image and a fusion type image can be formed on the image receiving body.

FIG. 2 is a partial schematic view showing a recording portion for forming an image on a dyeing layer as an embodiment of the recording method of the present invention. The illustration is omitted. FIG. 2 shows an example of a transfer body having a configuration having a coloring material layer and a dyeing layer on a substrate,
Unlike the case of FIG. 1, this is a recording method using a transfer body having a structure in which a dyeing layer is formed on the base material plane opposite to the base material plane on which the color material layer is located. The transfer body 20 is formed on a base material 21 in this order, such as a color material layer 22, a dyeing layer 23, a color material layer 24, and a dyeing layer 25. In addition, each dyeing layer is formed on the opposite side of the substrate.

The image formation on the dyeing layer 25 is performed by overlapping with any color material layer of the transfer body, for example, the color material layer 22. Since the color material layer 22 and the dyeing layer 25 are formed on opposite sides of a continuous base material, the transfer body runs in a spiral shape in order to overlap the color material layer surface and the dyeing layer surface. It is arranged to be. In FIG. 2, the transfer member 20 passes between the recording head 3 and the platen 4, via a roll 10, a speed setting roll 7, a vertically movable roll 9, a speed setting roll 8, and a roll 11, respectively. Later, recording head 3 and platen 4
The recording material 3 is sandwiched between the recording head 3 and the platen 4 so that the surface of the coloring material layer 22 and the surface of the dyeing layer 25 overlap. As described above, in a state where the transfer bodies 20 are sandwiched between the recording head and the platen under appropriate pressure, the dye of the color material layer is sublimated or transferred to the dyeing layer by the recording head, and the image is formed on the dyeing layer. It is formed. The position of the recording head is not limited to the base material side of the color material layer but may be on the base material side of the dyeing layer. Less than,
The description of the image formation on the dyed layer is omitted since it is the same as the description of FIG.

FIGS. 1 and 2 show an example of a structure in which a dyeing layer portion is provided directly on a substrate as a structure of a dyeing layer portion of a transfer body. However, a release layer and a dyeing layer are provided on a substrate. And a laminate in which a polymer material layer and a dyeing layer are laminated on a base material, or a release layer and a polymer material layer on a base material. Also in the case of a laminate in which a dyeing layer is laminated, after forming an image on the dyeing layer in the same manner as described above, the dyeing layer is separated from the release layer on the base material on the image receiving body 2 or from the base material. Transfer a laminate of the polymer material layer and the dyeing layer onto the image receiving body 2 away from the base, or transfer a laminate of the polymer material layer and the dyeing layer onto the image receiving body 2 away from the release layer on the base material Can be formed.

Next, a second recording method of the present invention will be described. 3 and 4 show the principle of a method of forming an image on an image receiving body by transferring a dyeing layer to an image receiving body and then fixing the dyeing layer to the image receiving body as each embodiment of the recording method of the present invention. FIG. FIG. 3 and FIG.
In each case, a portion for recording an image on the dyeing layer by the recording head shown in FIG. .

In FIG. 3, the dyed layer 18 having a recorded image
After passing between the heating roll 5 and the heating roll 6 under pressure, the dyeing layer 18 is separated from the base material 12 of the transfer body 1 on the roll 41 and is transferred onto the image receiving body 2. You. Thereafter, the dyeing layer 26 on the image receiving body is fixed to the image receiving body between the heating roll 27 and the silicone rubber roll 28 under pressure.
When the image receiving body is porous like paper, by sufficiently injecting (or filling) the dyeing layer 26 between the fibers of the paper, the gloss of the paper surface due to the dyeing layer is reduced, and the dyeing is apparently performed on the paper surface. The presence of the layer disappears. As a result, there is almost no visual distinction between the paper surface in the portion having the dyed layer and the paper surface in the portion having no dyed layer, and a very desirable recorded image can be obtained for recording on plain paper. The fixing performed by the heating roll 27 and the silicone rubber roll means that when the image receiving body is porous such as paper, it means that the adhesive strength between the dyeing layer and the paper is increased, or that the dyeing is performed as described above. It has the meaning of sufficiently filling the layer between the fibers of the paper.

In FIG. 3 and FIG. 4, a combination of a heating roll and a silicone rubber roll is used as the roll of the fixing portion. However, similarly to the case of the roll of the transfer portion, the roll of the fixing portion is used. The rule is not limited to this combination. In FIG. 3 and FIG. 4, a roll is used as a fixing means, but there is no particular limitation as long as it is a means for fixing the dyeing layer to the image receiving body by heat and / or pressure. For example, it can be obtained by passing an image receiving body between media whose at least one of them is heated and under appropriate pressing, or between media having high pressing force, or providing a suction means on the image receiving side. Alternatively, a light source having large radiant heat can be used. FIG.
As shown in FIG. 3, if the roll of the transfer portion and the roll of the fixing portion are provided separately, the number of rolls increases, so that the heating roll 5 of the transfer portion is replaced with the roll of the fixing portion. And the number of rolls was reduced. That is, in FIG.
And the silicone rubber roll 38 are rolls of the transfer portion, and the heating roll 5 and the silicone rubber roll 29 are rolls of the fixing portion.

As a roll or a heating roll, for example,
Rubber (rubber coated) roll such as silicone rubber, fluorine rubber, urethane rubber, etc., plastic roll, metal roll
And Teflon control are useful. Also, a flat medium, a thermal recording head, or the like may be used as the medium. Also, various heating methods using a halogen lamp, a nichrome wire, or the like can be used. It is particularly desirable to use two rolls, at least one of which is used by pressing a roll heated by, for example, a halogen lamp. As the method of applying heat and / or pressure, various methods can be used as described above for the transfer portion in FIG. Although the heating temperature is not particularly limited, it is usually used in the range of normal temperature to 300 ° C. Although the pressure is not particularly limited, it is usually used at 10 ⁸ Pa or less.

In FIGS. 3 and 4 described above, an example of a structure in which a dyeing layer is provided directly on a substrate as a structure of a dyeing layer portion of a transfer body is shown. The same applies to the transfer member of That is, in the case of a laminate in which a release layer and a dyeing layer are laminated on a substrate, or in the case of a laminate in which a polymer material layer and a dyeing layer are laminated on a substrate,
Alternatively, in the case of a laminate in which a release layer, a polymer substance layer and a dyeing layer are laminated on a base material, a dyeing layer or a polymer substance layer and a dyeing layer After the transfer of the laminate, the dyeing layer or the laminate is fixed on the image receiving member 2 by passing the image receiving member between the heating roll 27 and the silicone rubber roll 28 in FIG. You.
When the image receiving body is porous like paper, it is desirable that the dyeing layer or the laminate is sufficiently filled in the porous body by the fixing treatment.

FIG. 5 is a partial schematic view showing, in principle, a portion for transferring and fixing a laminate of a transfer body to an image receiving body as one embodiment of the recording method of the present invention. As a transfer body 30, a dye layer 3 having a polymer material layer 32 and a recorded image on a base material 31
3 shows a transfer member portion having a laminate 34 of No. 3 and a color material layer 35. Here, the color material layer 35 is a color material layer that has already been used for recording. After the laminate 34 is transferred onto the image receiving member 2 after passing between the two heating rolls 5 and 6 under pressure, the laminate 34 is pressed between the heating roll 27 and the silicone rubber roll 28 to be laminated. Is fixed on the image receiving body.

Next, a third recording method according to the present invention is a method of forming an image on an image receiving member by superimposing and integrating a transfer member having a dyeing layer having at least an image formed thereon and an image receiving member. Will be described.

FIG. 6 is a partial schematic diagram showing one part of a recording method as one embodiment of the present invention. FIG. 6 omits the process up to image recording on the dyed layer in FIG. 1, and shows another embodiment of the heating roll 5 and the heating roll 6 in FIG. By transferring the transfer body 1 having the dyed layer 18 on which an image is formed and the image receiving body 2 such as plain paper between the heating rolls 5 and 6 under appropriate pressure, the image receiving body is formed. 2 and the transfer body 1 can be integrated.
In this case, since the transfer body portion having the used coloring material layer 19 and the transfer body portion having the dyeing layer 18 are continuous with the base material 12, the transfer body portion having the dyeing layer 18 has been used. It is necessary to separate the transfer material from the transfer member having the color material layer 19. In the embodiment of FIG. 6, the configuration example in which the dyeing layer portion is provided directly on the substrate as the configuration of the dyeing layer portion of the transfer body is shown. The same applies to the case.

In the case of a transfer body having a laminate in which a release layer and a dyeing layer are laminated on a substrate, or a laminate in which a polymer material layer and a dyeing layer are laminated on a substrate, In the case of a transfer member having a transfer member, or a transfer member having a laminate in which a release layer, a polymer material layer, and a dyeing layer are laminated on a substrate, the transfer member is integrated with the image receiving member 2 in the same manner as described above. The dyeing layer, the release layer, and the substrate may be sequentially laminated on the image receptor, or the dyeing layer, the polymer layer, and the substrate may be sequentially laminated on the image receptor, or An image-formed product having a laminated structure of a dyeing layer, a polymer material layer, a release layer, and a substrate in this order is obtained on the body.

By integrating as described above, the image of the dyed layer on the image receiving member has an effect of being protected by the base material of the transfer member, and further, it is not necessary to laminate the protective film later. . When the transfer member has a release layer, it is possible to peel off the base material of the transfer member from the surface of the image receiver after integrating the image receiver and the transfer member. Further, even when the transfer body does not have a release layer, it is possible or impossible to peel off the base material of the transfer body from the surface of the image reception body after integrating the image receiver and the transfer body. Is also good.

The transfer member used in the recording method of the present invention comprises:
A transfer body having at least a color material layer and a dyeing layer at different positions on a substrate, or having at least a color material layer and a laminate at different positions on a substrate, wherein the laminate is dyed with a release layer. A transfer body, which is a laminate in which layers are sequentially laminated, or at least a color material layer and a laminate at different positions on a substrate, wherein the laminate has a polymer material layer and a dyeing layer sequentially laminated. Or a transfer body having at least a color material layer and a laminate at different positions on a substrate, wherein the laminate has a release layer, a polymer material layer, and a dyeing layer sequentially laminated.

The surface material or surface characteristics of the substrate may differ between the color material layer contact surface and the dyeing layer contact surface, or between the color material layer contact surface and the release layer contact surface. For example, when a color material layer is formed on a base material, a base material provided with an anchor coat layer on a polymer film is used to improve the adhesiveness between the base material and the color material layer. It is desirable to provide a color material layer on this anchor coat layer. In particular, the recording method of the present invention
Since an image is first recorded between the color material layer and the dyeing layer in one transfer body, the adhesive strength between the base material and the color material layer is strong during this image recording, while the adhesive strength between the base material and the dyeing layer is high. During the image recording with the color material layer, the substrate and the dyeing layer do not peel off,
This is because, for the transfer of the dyed layer to an image receiving body such as paper, a property of easily peeling off the transfer body substrate is required. In order to prevent heat fusion between the color material layer and the dyeing layer, it is desirable that the color material layer or the dyeing layer contains various release agents such as various silicone-based and fluorine-based materials. The receiver is uncoated paper,
Coated paper, film, sheet, synthetic paper, continuous image receiver, cut image receiver, and the like can be used without particular limitation on the material, paper quality, form, and the like.

The image formed on the image receiving body has a mirror image relationship with the image before transfer. Therefore, recording on the dyeing layer by the recording head is recording of a left-right reversed image with respect to the image formed on the normal receptor, except that the left-right reversal of the image formed on the receptor is not a problem.

Having at least a dyeing layer on one side, or a colorant layer on one side of the substrate, and a laminate on the other side,
The laminate is a sequential laminate of a release layer and a dyeing layer.

A transfer material having at least a coloring material layer and a dyeing layer (or a laminate) on a substrate has a surface material or surface characteristic of the substrate which is different from the color material layer contact surface and the dyeing layer contact surface (or the laminate). Object contact surface). The arrangement of the color material layer and the dyeing layer (or the laminate) on the substrate is not particularly limited as long as the color material layer and the dyeing layer can be recorded in an overlapping state. In general, a combination of a coloring material layer and a dyeing layer is combined with a coloring layer in which a coloring material layer is not adjacent due to the arrangement of a traveling system of a transfer body in a recording apparatus.
The color material layer and the dyeing layer (or the laminate) may be partially overlapped. The color material layer is a single color material layer,
Alternatively, as shown in FIG. 12, color material layers of a plurality of colors or more can be provided.

The substrate is not particularly limited. For example, there are various polymer films, polymer films surface-treated by coating or the like, various conductive films, and the like.
Examples of various polymer films include polyolefin-based, polyamide-based, polyester-based, polyimide-based, polyether-based, cellulose-based, polyparabanic acid-based, polyoxadiazol-based, polystyrene-based, and fluorine-based films. . In particular, films such as polyethylene terephthalate, polyethylene naphthalate, aramid, polyparabanic acid, polysulfone, triacetyl cellulose, polypropylene, cellophane, and moisture-proof cellophane are useful. Various polymer films include an anchor coat layer for improving adhesion to a color material layer and a release layer, a heat-resistant layer for reinforcing heat resistance such as thermal deformation of the polymer film, or a charging layer. An prevention layer or, if necessary, various coating layers may be provided. For example, as shown in FIG. 7, when the base material 53 is composed of the lubricating heat-resistant layer 52 on the lower surface of the polymer film 50 and the anchor coat layer 51 on a part of the upper surface, the lubricating heat-resistant layer 52 is formed of a substrate. To improve the running stability with a recording head such as a round head,
Has the effect of improving the adhesiveness between the polymer film 50 and the coloring material layer 54. As a base material, as shown in FIG. 8, a lubricating heat-resistant layer 52 and
A base material having an anchor coat layer 51 formed on the portion can be used. Further, as shown in FIG. 9, a substrate in which a lubricating heat-resistant layer 52 is formed on a part of the lower surface of the polymer film 50 and an anchor coat layer 51 is formed on the upper surface can be used. In particular, in the case of FIG. 9, since the anchor coat layer is also provided between the polymer film and the dyeing layer, the transfer body and the image receiving body of the dyeing layer portion are integrated to receive the image. Useful when forming an image on the body. Examples of various conductive films include, for example, polymer films containing various conductive particles such as carbon black and metal powder, polymer films having a conductive coating layer formed thereon, and polymer films having a conductive vapor-deposited layer. Useful. When a current-carrying head is used as a recording head, various conductive films as described above are required. When an image receiving body having an image is obtained by integrating a transfer body and an image receiving body, it is desirable that the substrate has excellent transparency.

The thickness of the substrate is not particularly limited, but is usually 2 to 30 μm. The thinner the thickness, as long as there is no problem in handling, the higher the recording sensitivity, the higher the transparency of the image when the transfer body and the receiver are integrated, and the more the transfer body is incorporated in the cassette. This is particularly advantageous, for example. Further, the thickness of the base material may be different between the portion where the coloring material layer is formed and the portion where the dyeing layer (or laminate) is formed.

The color material layer is composed of at least a color material and a binder. The color material is not particularly limited. For example, disperse dyes, basic dyes, color formers and the like are useful. Various polymers and the like can be used as the binder. For example, there are acrylic resin, styrene resin, urethane resin, polyester resin, polyvinyl acetal resin, vinyl acetate resin, amide resin, cellulose resin, chlorinated resin and the like. Examples of the cellulose resin include methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, carboxymethyl cellulose, nitrocellulose, cellulose acetate and the like. In particular, acrylonitrile-styrene copolymer resin, polystyrene, styrene-acryl copolymer resin, saturated polyester, polyester urethane, chlorinated rubber, chlorinated polypropylene, vinyl chloride resin, chlorinated vinyl chloride resin, vinyl chloride-vinyl acetate copolymer resin (and Vinyl alcohol, maleic acid, and other components may be copolymerized), vinyl chloride-acrylate copolymer resin (including a multi-component copolymer resin using a plurality of acrylic esters), vinyl acetate resin When at least one selected from the group consisting of polyvinyl acetal resin, polycarbonate and cellulose resin is used as a binder, recording sensitivity is high and / or excellent heat for a dyeing layer is obtained. Excellent in anti-fusing properties. The copolymer resin may be a copolymer resin composed of three or more components. In particular, polyvinyl alcohol such as polyvinyl formal, acetoacetated polyvinyl alcohol, propion acetalized polyvinyl alcohol, polyvinyl butyral, etc. is used for both the binder and the dyeing layer of the color material layer. The use of setal is particularly useful because of its high recording sensitivity. The glass transition point of the polymer is in the range of 40 ° C to 180 ° C, or the average degree of polymerization of the polymer is 200 to 270.
Those in the range of 0 are particularly desirable.

When the coloring material layer is formed by using at least one kind selected from a fluorine-containing moisture-curable resin or a siloxane-containing moisture-curable resin, at least a coloring material and a binder, Since the properties of a moisture-curable resin or a siloxane-containing moisture-curable resin as a release agent are very excellent, the thermal fusion phenomenon does not occur during thermal transfer recording in a combination of a coloring material layer and a dyeing layer. Can be recorded. The color material layer is at least one selected from a fluorine-containing moisture-curable resin or a siloxane-containing moisture-curable resin, and polyvinyl butyral, acetoacetated polyvinyl alcohol, polyvinyl formal, and propion acetate. -Polyvinyl alcohol, acrylonitrile-styrene copolymer resin, polystyrene, styrene-acryl copolymer resin, saturated polyester, polyester urethane,

As a fluorine-containing moisture-curable resin or a siloxane-containing moisture-curable resin, for example, JP-A-2-208
No. 9, a moisture-curable resin having a hydrolyzable silyl group or a resin obtained by introducing fluorine or silicone into a moisture-curable resin having a hydrolyzable isocyanate group can be used.

As the fluorine-containing moisture-curable resin, for example, a fluorine-containing polymer having a hydrolyzable silyl group, for example,
There is a moisture-curable resin described in JP-A-62-558, and a fluorine-containing acrylic silicone resin is particularly useful.
Further, a fluorine-containing polyurethane resin having a hydrolyzable isocyanate group at a molecular terminal or a side chain is also useful. Examples of the siloxane-containing moisture-curable resin include, for example, a siloxane-containing vinyl polymer having a hydrolyzable silyl group, and a siloxane-containing acrylic silicone resin is particularly useful.
Further, a siloxane-containing polyurethane resin having a hydrolyzable isocyanate group at a molecular terminal or a side chain is also useful. A fluorine-containing acrylic silicone resin, a siloxane-containing acrylic silicone resin, or the like may be modified with a urethane resin or the like. As a fluorine-containing acrylic silicone resin, for example, a fluorine-containing acrylic silicone resin solution (F-2A, Sanyo Chemical Industries, Ltd.), as a siloxane-containing acrylic silicone resin, for example, a siloxane-containing acrylic silicone resin solution (F-6A, Sanyo Chemical Industries, Ltd.) And a siloxane-containing moisture-curable resin having a hydrolyzable isocyanate group, for example, a siloxane-containing moisture-curable resin solution (SAT-300P, Shinko Giken Co., Ltd.).

In the coloring material layer, a reaction accelerator of a moisture-curable resin may be used if necessary. Examples of the reaction accelerator include titanates, amines, organotin compounds, acidic compounds and the like, for example, metal salts of carboxylic acids such as alkyl titanates, tin octylate, dibutyltin dilaurate and dibutyltin maleate. And amine salts such as dibutylamine-2-hexoate and the catalysts described in JP-A-58-19361 can be used. The addition amount of the reaction accelerator is usually 0.001 to 100% by weight based on the resin. When the moisture-curable resin is used in the form of a paint or the like, a storage stabilizer may be added if necessary.
There are stabilizers described in JP-A-724 and JP-A-57-147511.

The color material layer may have a multilayer structure. or,
A lubricating layer and various coating layers may be provided on the color material layer. In addition, various additives such as various silicone-based materials, various fluorine-based materials, or antistatic agents may be added to the coloring material layer in order to prevent thermal fusion during recording with the dyeing layer. good. Similarly, the upper layer of the multi-layer structure, fluorine-containing moisture-curable resin to prevent thermal fusion during recording with the dyeing layer,
Siloxane-containing moisture-curable resin, various silicone-based materials,
Various additives such as various fluorine-based materials or antistatic agents may be added.

The dyeing layer is formed using at least a polymer. The dyeing layer may contain a developer such as an electron-accepting substance, if necessary (for example, when a leuco dye or the like is used for the colorant layer). Examples of the electron-accepting substance include phenol compounds such as bisphenol A, carboxylic compounds, silica, and activated clay. Various polymers can be used as the polymer. For example, various polymers described in the section of the binder for the color material layer are particularly useful. That is, there are acrylic resin, styrene resin, urethane resin, polyester resin, polyvinyl acetal resin, vinyl acetate resin, amide resin, cellulose resin, chlorinated resin and the like. In particular, acrylonitrile-styrene copolymer resin, polystyrene, styrene-acryl copolymer resin, saturated polyester, polyester urethane, chlorinated rubber, chlorinated polypropylene, vinyl chloride resin, chlorinated vinyl chloride resin, vinyl chloride-vinyl acetate copolymer resin (and Vinyl alcohol, maleic acid, and other components may be copolymerized), vinyl chloride-acrylate copolymer resin (including a multi-component copolymer resin using a plurality of acrylic esters), vinyl acetate resin At least one selected from the group consisting of polycarbonate, cellulose resin and cellulose resin.
When the seed is used, it has good recording sensitivity and / or has excellent heat-sealing prevention properties for the color material layer, and is good. The glass transition point of the polymer is in the range of 40 ° C to 150 ° C, or the average degree of polymerization of the polymer is 200 to 2700.
Are particularly desirable. The average degree of polymerization is 1500 or less for the purpose of transferring the dyeing layer to the image receiving body or fixing (filling or injecting) the dyeing layer resin into the fiber of the paper when the image receiving body is porous such as paper. A polymer having a small molecular weight or a polymer having a flow softening point of 200 ° C. or lower is particularly desirable. Since the dyeing layer on which the image has been formed is transferred onto (or integrated with) the image receiving member, it is desirable that the dyeing layer be transparent. Therefore, a highly transparent polymer is desirable.

As the polymer of the dyeing layer, polyvinyl acetal is particularly desirable. Polyvinyl acetal is a resin obtained by reacting polyvinyl alcohol with various aldehydes such as formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde and the like. For example, polyvinyl formal, acetoacetated polyvinyl alcohol, propion acetalized polyvinyl alcohol, polyvinyl butyral and the like are particularly useful.
The polyvinyl acetal may, of course, be one synthesized by adding a mixture of various aldehydes or other reactive compounds to polyvinyl alcohol. Polyvinyl acetal has a polar group having an acetal structure, and thus exhibits excellent dyeing properties for disperse dyes and the like. Also, the aceta
The terminal of the structure has a non-polar group such as hydrogen or an alkyl group more than a methyl group. The better the heat-sealing prevention properties, the better.

Therefore, the longer the alkyl group is and the greater the degree of acetalization is, the greater the thermal fusion preventing property is. It was also found that the longer the alkyl group and the greater the degree of acetalization, the lower the glass transition point, and therefore the higher the recording sensitivity. Due to the above properties, when polyvinyl acetal is used for the dyeing layer, it does not easily fuse to the colorant layer and exhibits high recording sensitivity.

From the viewpoint of recording sensitivity or transfer characteristics to the image receiving member, polyvinyl acetal obtained from a polyvinyl alcohol having an average degree of polymerization of 2700 or less is preferable as the polyvinyl acetal. In particular, the flow softening point is 2
50 ° C. or less is desirable. Flow softening point (flow start temperature)
Is a value measured by a flow tester (heating rate: 6
° C / min, extrusion pressure: 9.8 × 10 ⁶ Pa , die: φ
1 mm x 10 mm). For example, when the image receiving body is paper, polyvinyl acetal obtained from a low molecular weight polyvinyl alcohol having an average degree of polymerization of 1500 or less, or flow softening, for the purpose of injecting the dyeing layer resin into the fibers of the paper. Polyvinyl acetal having a temperature of 200 ° C. or lower is particularly desirable. The higher the degree of acetalization, the greater the thermal fusion prevention property with respect to the color material layer.
Desirably, it is 0 mol% or more. In particular, when the degree of butyralization of polyvinyl acetal is 50 mol% or more, it is desirable because the heat-sealing prevention property and the recording sensitivity to the color material layer are particularly excellent. Polyvinyl butyral has a high degree of butyralization because the higher the degree of butyralization and the lower the degree of polymerization, the lower the softening point and the easier the transfer or fixing characteristics to the image receiving body. Or polyvinyl butyral having a low degree of polymerization is particularly useful.

As polyvinyl butyral, for example, a product of Sekisui Chemical Co., Ltd., BL-1 (butyralization degree = 63 ± 3 mol%, flow softening point, 105 ° C.), BL
-2 (butyralization degree = 63 ± 3 mol%, flow softening point, 120 ° C.), BH-S (butyralization degree = 70 mo)
1% or more, flow softening point, 160 ° C.), BM-S (butyralization degree = 70 mol% or more, flow softening point, 150
° C), BL-S (butyralization degree = 70 mol% or more)
Flow softening point, 110 ° C.), BH-3 (butyralization degree = 65 ± 3 mol%, flow softening point, 205 ° C.), BM
-2 (butyralization degree = 68 ± 3 mol%, flow softening point, 140 ° C.), BM-1 (butyralization degree = 65 ± 3)
mol%, flow softening point, 130 ° C.), BM-5 (butyralization degree = 65 ± 3 mol%, flow softening point, 160)
° C) and the like are particularly useful. The polyvinyl acetal may react with a phenol resin, an epoxy resin, a melamine resin, an isocyanate compound, a dialdehyde compound or the like to form a crosslinked structure. Polyvinyl acetal does not exhibit tackiness at room temperature, so that it has good bleed resistance of recorded images and is easy to handle.

In particular, when polyvinyl acetal is formed as a dyeing layer on a polyester substrate such as polyethylene terephthalate, the adhesiveness to the polyester film is very small, so that the polyvinyl acetal is easily peeled off from the polyester film. However, during thermal transfer recording with the color material layer, it is held on the base material, and has the property of being easily transferred to the image receiving body during transfer to the image receiving body. The reason for this is that polyvinyl acetate is used during thermal transfer recording between the coloring material layer and the dyeing layer.
The polyester film is in a heat-softened state at a temperature equal to or higher than the glass transition point, and in this heat-softened state, the polyvinyl acetal is retained on the polyester film side because the adhesiveness to the color material layer in the heat-softened state is sufficiently small. It is thought that it is done. When an image is recorded on the polyvinyl acetal dyeing layer as described above, the softening point of the polyvinyl acetal is higher than that of polyvinyl acetal containing no dye because the polyvinyl acetal contains a dye. Decrease. Therefore, when the dyeing layer is subsequently transferred to the image receiving body, the dyeing layer is considered to be more easily transferred and adhered to the image receiving body. The transfer to the image receiving body is more easily performed especially when the image receiving body is plain paper or the like, because the dyeing layer resin is entangled with the paper fibers. Also, when polyvinyl butyral having a degree of butyralization of 50 mol% or more is used as a binder for the color material layer, the property for preventing thermal fusion to the dyeing layer is excellent, which is also favorable. In particular, a butyralization degree of 50 mol is applied to one of the binder and the dyeing layer of the color material layer.
% Or more of polyvinyl butyral, and a polymer other than polyvinyl butyral is desirably used in combination with a polymer having different properties to improve the heat-sealing prevention property. In particular, acrylonitrile-styrene copolymer resin, polystyrene, styrene-acryl copolymer resin, saturated polyester, polyester urethane, chlorinated rubber, chlorinated polypropylene, vinyl chloride resin, chlorinated vinyl chloride resin as polymers other than polyvinyl butyral, Preference is given to vinyl acetate resins, vinyl chloride-vinyl acetate copolymer resins, vinyl chloride-acrylate copolymer resins, polycarbonates and cellulose resins.

When the dyeing layer is formed by using at least one selected from a fluorine-containing moisture-curable resin and a siloxane-containing moisture-curable resin, the heat-sealing prevention property is particularly excellent. Therefore, no thermal fusion with the color material layer occurs at the time of thermal transfer recording. Since the fluorine-containing moisture-curable resin and the siloxane-containing moisture-curable resin have already been described in the section of the color material layer, the description is omitted. The dyeing layer is at least one selected from a fluorine-containing moisture-curable resin or a siloxane-containing moisture-curable resin, and polyvinyl butyral;
, Acetoacetated polyvinyl alcohol, polyvinyl formal, propion acetalized polyvinyl alcohol, acrylonitrile-styrene copolymer resin, polystyrene, styrene-acryl copolymer resin, saturated polyester, polyester urethane, chloride Rubber, chlorinated polypropylene, vinyl chloride resin, chlorinated vinyl chloride resin, vinyl chloride-vinyl acetate copolymer resin, vinyl chloride
It is particularly favorable when the film is formed using at least one selected from an acrylate copolymer resin, a vinyl acetate resin, a polycarbonate and a cellulose resin. In particular, the dyeing layer formed of a combination of polyvinyl acetal having excellent heat-sealing prevention properties and a fluorine-containing moisture-curable resin and / or siloxane-containing moisture-curable resin having excellent heat-sealing prevention properties is colored. Shows excellent heat-sealing prevention properties for the material layer. The description regarding polyvinyl acetal described in the section of the dyeing layer is also useful when polyvinyl acetal is used as a binder for the color material layer.

In the recording method of the present invention, at least a transfer member used in a recording method having a process of transferring a dye layer to an image receiving member is a case where recording is performed on a conventional dye layer provided on the image receiving member. Unlike the first recording on the dyed layer,
Since the dyeing layer does not peel off to the color material layer side and needs to have the property of peeling on the image receiving body after recording, the property of preventing thermal fusion between the color material layer and the dyeing layer is particularly important. In particular, when a release layer is provided on a base material, the dyeing layer is easily separated from the release layer during recording with the color material layer, but polyvinyl butyral having a butyralization degree of 50 mol% or more is used. Alternatively, by using at least one selected from a fluorine-containing moisture-curable resin and a siloxane-containing moisture-curable resin for the colorant layer or the dyeing layer, the image can be stably recorded on the dyeing layer.

The release layer 59 is not particularly limited. For example, when the release layer is formed by using at least one selected from a fluorine-containing moisture-curable resin and a siloxane-containing moisture-curable resin, particularly excellent release characteristics are exhibited. Alternatively, the release layer may be formed using at least one selected from a fluorine-containing moisture-curable resin or a siloxane-containing moisture-curable resin and a polymer material. Alternatively, the release layer may be formed of the following various release agents or various release agents and a polymer substance. For example, as silicone-based mold release agents, various silicone oils having excellent stability represented by dimethyl silicone oil, phenyl silicone oil, fluorine silicone oil, SiH modified, silanol modified, alkoxy modified , Epoxy-modified, amino-modified, carboxyl-modified, alcohol-modified, mercapto-modified, vinyl-modified, polyester-modified, fluorine-modified, higher fatty acid-modified, carnauba-modified, amide-modified, alkylallyl-modified, etc. Various silicone rubbers such as silicone oil, heat vulcanization type, room temperature curing type, liquid type, various silicone resins such as condensation reaction type, addition reaction type, peroxide curing reaction type, various silicone emulsions, various types There are silicone resin powder, silicone rubber powder and the like.

Various fluorine rubbers such as vinylidene fluoride-hexafluoropropylene rubber, various fluorine surfactants, carbon fluoride, various fluorine rubber latex, and fluorine-containing resins are useful. In addition, release agents such as various fatty acid esters, various waxes and various oils are useful. Release layer 59
When a polymer is used, the polymer is not particularly limited. For example, various polymers described for the polymer material layer 66 can be used. If necessary, it may be used together with the various release agents described above. In particular, various curable resins using heat, light, electron beams or the like are useful. An adhesive layer or the like may be provided between the base material and the release layer. When obtaining a receiver having an image by integrating the transfer member and the receiver,
It is desirable that the release layer has excellent transparency.

The polymer material layer 66 is formed using at least a polymer. The polymer is not particularly limited.
As the polymer, for example, various thermoplastic resins, various curable resins by heat, light, electron beam or the like can be used. For example, various resins such as acrylic, urethane, amide, ester, cellulose, styrene, and olefin resins can be used. Examples of light or electron beam curable resins include various acrylate resins such as polyester acrylate, epoxy acrylate, urethane acrylate, and silicone acrylate, unsaturated cycloacetal compounds and epoxy resins. Is useful.
A water-soluble or water-dispersible resin is useful because it has excellent solvent resistance as an undercoat layer for dyeing layer coating. In particular, the polymer material layer is formed using at least one selected from polyvinyl alcohol, polyvinyl alcohol derivative, cellulose derivative, modified starch, starch derivative, chlorinated resin, and polycarbonate. If it is, an aromatic solvent such as toluene,
It has excellent solvent resistance when applied to a dyeing layer forming paint using a ketone-based solvent such as butanone, and is not very strong in adhesiveness to polyester film, which is a typical base material. Has features. Examples of the polyvinyl alcohol derivative include various polyvinyl acetals described in the dyeing layer. Examples of the cellulose derivatives include methylcellulose, ethylcellulose, hydroxyethylcellulose, carboxymethylcellulose, nitrocellulose and cellulose acetate. Examples of the modified starch include oxidized starch and enzyme-treated starch. Examples of the starch derivative include hydroxyethyl starch, carboxymethyl starch, cyanoethylated starch and the like. Examples of the chlorinated resin include chlorinated polyethylene, chlorinated polypropylene, and chlorinated rubber. Since these resins do not exhibit tackiness at room temperature, even if they are adjacent to the dyeing layer, the dyeing layer has good bleed resistance to the dye in the recorded image and is easy to handle. It is desirable that the polymer has a glass transition point of 50 ° C. or higher from the viewpoint of the storage reliability of the recorded image. For example, when paper is used as the image receiving member, the average degree of polymerization of the polymer is in the range of 200 to 2700 or the flow softening point is in the range of 80 to 250 ° C. for the purpose of injecting the polymer into the fiber of the paper. Is desirable.
In particular, a polymer having an average degree of polymerization of 1500 or less or a flow softening point of 200 ° C. or less is particularly desirable.

When the polymer material layer 66 is formed using at least one selected from a fluorine-containing moisture-curable resin or a siloxane-containing moisture-curable resin and a polymer, This is useful because the releasability of the polymer material layer is easily controlled. Polymer material layer 66
Is transferred onto (or integrated with) the image receiving member, so that the polymer material layer is desirably transparent. Therefore, a highly transparent polymer is desirable.

The polymer material layer 66 serves as an adhesion control layer between the base material and the dyeing layer 55, or between the release layer 59 and the dyeing layer 55, or a thin film coating of the dyeing layer 55. The effect as an undercoat layer can be obtained, and when it is transferred on the image receiving body and is on the image receiving body, it is located on the dyeing layer, and thus the light resistance, abrasion resistance, etc. of the dyeing layer And the effect of a pencil writable layer on the image surface of the image receiving body can be obtained. The polymer material layer may have a multilayer structure. The polymer material layer may be a layer formed by coating, hot melt or the like, or a polymer film.

The coloring material layer, the dyeing layer or the polymer material layer has a heat-sealing prevention property between the coloring material layer and the dyeing layer or a peeling property between the base material and the dyeing layer (or the polymer material layer). for,
At least on the surface thereof, the various release agents described in the description of the release layer may be contained alone or in combination. The dyeing layer (or polymer material layer and dyeing layer) is made of paper, OHP
When the image is transferred to an image receiving body such as a film, the surface of the image may be required to be writable with a pencil or the like. Various fine particles such as synthetic amorphous silica, titanium oxide, calcium carbonate and alumina, or transparent fine particles may be added in order to give good dyeability to the dyeing layer or the polymer material layer. In particular, when the dyeing layer (or the polymer material layer and the dyeing layer) is sufficiently fixed to the inside of the fiber between the fibers, very excellent writing properties are exhibited even if fine particles are not contained. Of course, fine particles and the like may be added. When the dyeing layer portion of the transfer body is integrated with the image receiving body, the base material is in a state of being laminated on the image surface, so that the base material surface may have writability. For example, it is effective to use a roughened film or a film to which writability is imparted by coating as a substrate.

The dyeing layer (or polymer layer) may contain an ultraviolet absorber, an antioxidant, a fluorescent agent, etc. in order to improve the image light resistance and the like. Since the polymer layer functions as a light-resistant protective layer of the dyeing layer, it is more effective to add an ultraviolet absorber, an antioxidant, and the like. When the base material or the release layer is also integrated with the image receiving member, an ultraviolet absorber, an antioxidant, etc. is added to function as a light-resistant protective layer of the dyeing layer, or the ultraviolet absorber, the antioxidant It is more effective to have a layer to which an agent or the like is added. Further, the polymer material layer may be a polymer material layer which dyes or develops a color in the coloring material layer like a dyeing layer.

Various antistatic agents and the like may be added to the coloring material layer, the dyeing layer, the release layer or the polymer material layer. Various fine particles and the like may be added to the color material layer or the release layer. The transfer body may have, for example, various transfer layers such as a white hiding layer, an adhesive layer, and a pigment ink layer, a non-transfer layer, and various laminates in addition to the color material layer and the dyeing layer (or the laminate). good.

The image receiving member is made of uncoated paper, coated paper, film,
Sheet, synthetic paper, continuous image receiver or cut image receiver, etc.
In particular, it can be used without being limited to its material, paper quality, form and the like.

As described above, by using the thermal transfer recording method or the transfer body of the present invention, recording paper in any form such as plain paper, transparent film for OHP, bond paper having a large surface roughness, coated paper, and coated film.
