Description

The present invention relates to images how to process.

  It is known that by providing an information processing member on a reversible thermosensitive recording medium, the internal information of the information processing member can be rewritten and an image can be formed on the reversible thermosensitive recording medium based on the recorded information.

  When forming and erasing an image on such a reversible heat-sensitive recording medium, a heating device such as a thermal head, a heat roll, or a ceramic bar is pressed. It is formed. For this reason, when the heating device is pressed, the reversible thermosensitive recording medium cannot be heated uniformly, resulting in poor coloring and decoloring. Further, the portion provided with the information processing member of the reversible thermosensitive recording medium has a problem that the information recording element is peeled off from the reversible thermosensitive recording medium or damaged when the heating device is pressed.

  Therefore, a configuration is known in which only the area of the reversible thermosensitive recording medium with a non-contact IC tag that is not attached with the non-contact IC tag is known (see Patent Document 1). Thereby, the thermal damage of the non-contact type IC tag can be prevented, and the occurrence of uneven color disappearance and color unevenness can be prevented. However, in this method, the area where the image is formed is limited.

On the other hand, a data carrier in which an IC circuit having an antenna part and an information storage part is included in a support member, a pressure-sensitive adhesive sheet for display provided with a heat-sensitive recording layer on one side of the cushioning base material and an adhesive layer on the other side It is known that clear color development and complete decoloring can be achieved by sticking to the surface (see Patent Document 2). However, in this configuration, since the information storage unit is included in the support member, it is difficult to form a reversible thermosensitive recording medium having flexibility, and the application range is limited.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, the reversible thermosensitive recording medium of the present invention comprises a support 11 having flexibility, a reversible thermosensitive recording layer 12, an information processing member 13 having an information recording element, and a buffer layer 14. The information processing member 13 and the buffer layer 14 are laminated on the opposite side of the reversible thermosensitive recording layer 12 provided on the support 11. Here, having flexibility means that when one end of an object is fixed, the other end can hang down under its own weight.In the present invention, the end of the sheet is held horizontally, The other side hangs down. In addition, the standard which hangs down is 45 degree | times or more and 90 degrees or less. FIG. 1 shows a configuration in which the buffer layer 14 is provided between the support 11 and the information processing member 13, and FIG. 2 shows a configuration in which the information processing member 13 is provided between the support 11 and the buffer layer 14. 1 and 2, (a), (b), and (c) are the surface on the side where the information processing member and the buffer layer of the reversible thermosensitive recording medium are provided, the cross section and the length in the width direction, respectively. A cross section in the vertical direction is shown. Thereby, when the heating device comes into contact with the reversible thermosensitive recording medium, unevenness caused by the information processing member is reduced. For this reason, it is possible to improve the coloring failure when forming an image and the erasing failure when erasing the image, and reduce the damage of the information recording element. Furthermore, the reversible thermosensitive recording medium can have flexibility by processing into a roll shape and a sheet shape. Note that secondary processing such as etching may be performed.

  The reversible thermosensitive recording medium of the present invention displays the information recorded on the information processing member on the reversible thermosensitive recording layer, so that information can be confirmed without a special device, and convenience is improved. . An IC chip is preferable as the information recording element, and a non-contact IC tag is preferably used as the information processing member. Reversible heat-sensitive recording media are used for entrance / exit tickets, frozen food containers, industrial products, stickers for various chemical containers, logistics management applications, manufacturing process management, document management applications, etc., and are processed into general document sizes such as A4 size. can do.

  As shown in FIG. 3, the information processing member is formed by forming an IC circuit 31 and an antenna circuit 32 on a circuit board 33.

  As a base material used for a circuit board, a rigid type such as general paper phenol, glass epoxy, and composite, a flexible type such as polyimide film, polyester film, paper, and synthetic paper, and a composite type of both can be used. The wiring circuit is a method of providing a coiled metal conductive wire on the circuit board using an adhesive, a method of providing the film by deforming the film by heating and pressing, or a metal of a circuit board stretched with a metal such as copper or aluminum. A method of etching a part, a method of transferring a metal foil formed of a conductive metal such as silver onto a circuit board, and printing by silk screen printing using a conductive paste paint, followed by drying and a circuit board The method of providing above is mentioned.

  The information processing member is formed by mounting an IC circuit on a circuit board on which a wiring circuit is formed, and electrically connecting the antenna circuit and the IC circuit. For mounting the IC circuit on the circuit board, TAB (Tape Automated Bonding), COB (Chip on Board) and flip chip mounting are used. Ordinary soldering or conductive adhesive can be used for mounting an IC circuit or connecting to an antenna circuit, but it is necessary to adopt a temperature condition that the circuit board can withstand during processing. At this time, an IC circuit layer may be formed by embedding (packaging) with an epoxy resin or the like in order to protect the mounted IC circuit or wiring circuit. The thickness of the IC circuit layer embedded with the epoxy resin is usually 150 μm or more and 1 mm or less. For protection, a protective film such as a polyimide film or a polyester film can be adhered to the IC circuit exposed surface.

The adhesive layer to which the information processing member is bonded is usually one that can be pressure bonded at room temperature or in a heated state. Examples of the adhesive include a liquid anchor coat agent. Specifically, as a polyurethane anchor coating agent, EL-150 (manufactured by Toyo Morton) or a mixture of BLS-2080A (manufactured by Toyo Morton) and BLS-2080B (manufactured by Toyo Morton), as a polyester anchor coating agent AD-503 (manufactured by Toyo Morton Co., Ltd.) can be applied. Note that anchor coating agent is preferably coated to a 0.5 g / ^{m 2} or more 25 g / ^{m 2} or less.

  The information processing member is preferably in the form of a sheet because it is used by being attached to a flexible support or buffer layer. Further, it is preferable that the information recording element has no projection and has a smooth surface. Note that when an information processing member having a general information recording element is bonded to a metal surface, the magnetic flux is blocked by the metal, and a sufficient electromotive force may not be secured. An information processing member composed of a coil or an information processing member composed of a high permeability core, an antenna coil, and a conductive metal may be used. Although such an information processing member is difficult to reduce in thickness, a sufficient electromotive force can be obtained even if it is used on a metal surface, so that it has a great advantage of being used in a sheet shape.

  The pressure-sensitive adhesive layer that adheres the information processing member can be variously selected depending on the type of adherend, the environment in which it is used, the strength of adhesion, and the like. The pressure-sensitive adhesive layer can be formed by applying a commonly used water-based or solvent-based pressure-sensitive adhesive and drying it. These pressure-sensitive adhesives can be used in the form of an organic solvent solution or dispersion, an aqueous dispersion such as an emulsion.

  The adhesive layer and the pressure-sensitive adhesive layer are preferably provided on the IC circuit side of the circuit board so as not to be affected by the unevenness of the IC circuit. Moreover, in order to reduce the level | step difference of an information processing member, it is desirable that it is the same material and an equivalent film thickness.

  As main components of the adhesive layer and the adhesive layer, urea resin, melamine resin, phenol resin, epoxy resin, vinyl acetate resin, vinyl acetate-acrylic copolymer, ethylene-vinyl acetate copolymer, acrylic resin, polyvinyl Ether resin, vinyl chloride-vinyl acetate copolymer, polystyrene resin, polyester resin, polyurethane resin, polyamide resin, chlorinated polyolefin resin, polyvinyl butyral resin, acrylate copolymer, methacrylic resin Examples include acid ester copolymers, natural rubber, synthetic rubber, cyanoacrylate resins, and silicone resins. These may be mixed according to a use, and various additives may be added. Furthermore, if the adhesive strength can be set as required and a certain level of adhesive strength can be secured at the fine wrinkles on the surface, the information recording part can be easily detached and repeated. Will be able to use. Moreover, if the adhesive strength is high and it is difficult to peel off after attachment, it can be used semipermanently. In addition, a reversible thermosensitive recording layer may be provided by laminating a peelable sheet such as paper pattern on the adhesive layer or the adhesive layer. Furthermore, various treatments such as easy adhesion, water repellency, oil repellency, and antistatic may be applied to the surfaces other than the adhesion surface as necessary.

  In the present invention, when the buffer layer is viewed in plan, the buffer layer region preferably includes the information processing member region. Here, the width of the buffer layer region is preferably not less than the width of the reversible thermosensitive recording layer image forming region and not more than the width of the reversible thermosensitive recording layer region. If this width is smaller than the width of the reversible thermosensitive recording layer, an image cannot be formed. If the width is larger than the width of the reversible thermosensitive recording layer, it is difficult to convey by the image forming apparatus. It is not preferable. The ratio of the length of the buffer layer region to the length of the information processing member region is preferably 1 or more and 1.5 or less. When this ratio is less than 1, the function of the buffer layer with respect to the information processing member cannot be sufficiently exhibited, and when it exceeds 1.5, it becomes difficult to enter the tray of the image forming apparatus, which is not preferable.

  In the present invention, the thickness of the buffer layer is preferably 0.5 times or more the thickness of the information processing member. If the thickness of the buffer layer is smaller than 0.5 times the thickness of the information processing member, the function of the buffer layer cannot be fully exhibited.

In the present invention, the buffer layer contains a material selected from the group consisting of a soft resin material, a mixed material of a hard resin material and a soft resin material, a mixed material of an inorganic material and a soft resin material, a sponge material, and a rubber material. It is preferable to do. As a result, it is possible to improve the coloring failure when forming an image and the decoloring failure when erasing the image, and reduce the damage of the information recording element. Examples of the soft resin material include acrylic resin, non-woven fabric, and silicone resin. Examples of the hard resin material include organic fillers. Examples of the inorganic material include inorganic fillers. Examples of the sponge material include foamed polyurethane. Examples of the rubber material include NBR and polyurethane resin. The density of the sponge material is desirably 20 kg / m ³ or more and 60 kg / m ³ or less. If this density is less than 20 kg / m ³ , the buffer layer is too soft and the information recording part is bare, and if it is more than 60 kg / m ³ , the surface is too hard and the reversible thermosensitive recording layer A level difference is formed, causing poor coloring and decoloring. The sponge material or rubber material having a density greater than 60 kg / m ³ desirably has a hardness (JIS K6253) of 20 degrees or more and 70 degrees or less. If the hardness is less than 20 degrees, the support is too soft and the buffer layer is broken. On the other hand, if the hardness is greater than 70 degrees, the surface is too hard and a step is formed with the reversible thermosensitive recording layer, resulting in poor color development and decoloration.

  In the present invention, the buffer layer preferably has an adhesive layer or a pressure-sensitive adhesive layer on the surface in which the content of at least one of the curable resin material and the inorganic material is 30% by weight or more and 90% by weight or less. This is because the adhesive layer and the pressure-sensitive adhesive layer are soft by themselves, so that the function of the buffer layer is hardly exhibited. By adding a material having high hardness, the fluidity of the adhesive layer and the pressure-sensitive adhesive layer is suppressed, and the function of the buffer layer can be expressed. In addition, when said content rate is smaller than 30 weight%, the added effect will not come out, and when it exceeds 90 weight%, the hardness of an adhesive layer and an adhesion layer will become high too much and it will become weak. The curable resin and the inorganic material each have a fibrous shape, a needle shape, a spherical shape, or an irregular shape. These may be mixed and used according to the application, or various additives may be added. Furthermore, the adhesive strength can also be set as needed.

  In consideration of unevenness in the transport direction when forming and erasing an image, the information recording unit and the buffer layer are preferably attached to the transport start part or transport end part of the reversible thermosensitive recording medium. When the material of the information recording part and the buffer layer is significantly different, or when the material is unknown, the unevenness may increase when pressed by the pressure of the heating device, etc. It is possible to further reduce the unevenness, and it is possible to improve color development failure during image formation and color erasure failure during image erasure.

  In the present invention, the reversible thermosensitive recording layer contains a material whose color tone reversibly changes with temperature. The change in color tone includes changes in transmittance, reflectance, absorption wavelength, scattering degree, and the like, and the reversible thermosensitive recording layer displays by combining these changes. As a material whose color tone changes reversibly, a material whose transparency and color tone change reversibly by heat is preferable. Specifically, the state of the first color becomes a state of the first color at a first specific temperature higher than normal temperature, the state of the second color by heating to a second specific temperature higher than the first specific temperature and then cooling. What will be mentioned. In particular, a material whose color state changes between the first specific temperature and the second specific temperature is preferably used. As such a reversible thermosensitive recording layer, a reversible thermosensitive recording layer containing a leuco dye and a developer is preferable.

  Examples of the leuco dye include known dye precursors such as a phthalide compound, an azaphthalide compound, and a fluorane compound, and can be used alone or as a mixture of two or more.

  As the developer, a structure having a color developing ability to develop a leuco dye such as a phenolic hydroxyl group, a carboxyl group or a phosphate group in the molecule and a structure in which a long chain hydrocarbon group for controlling the cohesive force between molecules is connected. And compounds having one or more of each. The connecting part of the long chain hydrocarbon group may be via a divalent or higher valent connecting group containing a hetero atom, and the long chain hydrocarbon group contains at least one of the same connecting group and aromatic group. Also good. Specific examples of the developer are described in JP-A-9-290563 and JP-A-11-188969, and may be used alone or as a mixture of two or more.

  In the present invention, in order to develop a color in the reversible thermosensitive recording layer, it may be heated once above the color development temperature and then rapidly cooled. Specifically, when the recording layer is heated for a short time with a thermal head or a laser beam, the recording layer is locally heated, so that the heat is immediately diffused and abrupt cooling occurs and the colored layer is fixed. On the other hand, in order to erase the color, it may be heated and cooled for a relatively long time using an appropriate heat source, or may be temporarily heated to a temperature slightly lower than the coloring temperature. When heated for a long time, the temperature of a wide range of the reversible thermosensitive recording layer rises, and the subsequent cooling becomes slow. As a heating method in this case, a hot roll, a hot stamp, hot air, or the like may be used, or heating may be performed for a long time using a thermal head. In order to heat the reversible thermosensitive recording layer to the decoloring temperature range, for example, by adjusting the voltage and pulse width applied to the thermal head, the energy applied during decoloring is lower than the energy applied during color development. It is good to let them. If this method is used, color development and decoloration can be performed only with the thermal head, and so-called overwriting becomes possible. Further, the color can be erased by heating to a decoloring temperature range with a heat roll or a heat stamp.

  An additive may be added to the reversible thermosensitive recording layer in order to improve or control the coating characteristics and the color developing / decoloring characteristics. Examples of the additive include a surfactant, a conductive agent, a filler, an antioxidant, a coloring stabilizer, and a decoloring accelerator.

  The reversible thermosensitive recording layer contains a resin in addition to the leuco dye, the developer and the additive. The resin used for the reversible thermosensitive recording layer is not particularly limited as long as these materials can be bound on the support, and known resins can be used alone or as a mixture of two or more. Among these, in order to improve durability when repeatedly forming images, a curable resin that is cured by heat, ultraviolet rays, electron beams, or the like is preferably used, and a thermosetting resin is particularly preferably used. Specifically, a resin having a group that reacts with a curing agent such as acrylic polyol resin, polyester polyol resin, polyurethane polyol resin, polyvinyl butyral resin, cellulose acetate propionate, or cellulose acetate butyrate, or a group that reacts with the curing agent. Examples thereof include a resin obtained by copolymerizing a monomer having the same. Further, when cured, the gel fraction of the recording layer is preferably 30% or more. If it is lower than this, the cured state is not sufficient, and the durability is not sufficiently improved. This value is more preferably 50% or more, and particularly preferably 70% or more. The ratio of the weight of the resin to the weight of the color forming component in the reversible thermosensitive recording layer is preferably from 0.1 to 10. When this ratio is less than 0.1, the heat intensity of the reversible thermosensitive recording layer is insufficient, and when it is more than 10, the color density is lowered, which causes a problem.

  The curing agent is not particularly limited, but an isocyanate curing agent is preferable. Specific examples include hexamethylene diisocyanate, tolylene diisocyanate, xylylene diisocyanate, isophorone diisocyanate, and adduct types, burette types, isocyanurate types, blocked isocyanates and the like based on these trimethylol propane. Among these, hexamethylene diisocyanate is preferable, and this adduct type, burette type, and isocyanurate type are preferably used. The total amount of the curing agent may not be cured. That is, an unreacted curing agent may be present. Further, when curing, a catalyst may be added.

In order to reduce the image quality, it is preferable to provide an intermediate layer between the two, which can improve image storage stability.

  In the present invention, instead of providing a heat insulating layer, a support that also serves as a heat insulating layer may be used. As such a support, it is common to use a plastic film or synthetic paper. Synthetic paper containing manufactured microvoids is preferred.

  In this invention, it is preferable that the protective layer is further provided in the side in which the information processing member and the buffer layer are provided. Thereby, the damage of the information recording element can be further reduced. The protective layer used here is the same as described above.

  As shown in FIG. 4, the image processing apparatus according to the present invention recognizes the information in the information recording unit of the reversible thermosensitive recording medium with the antenna 41 and then erases the image of the reversible thermosensitive recording unit with the heat roll 42. Then, an image is formed on the reversible thermosensitive recording section by the thermal head 43 and conveyed by the conveying roller 44. Here, the distance between the heat roll 42 and the thermal head 43 is preferably not less than the length of the reversible thermosensitive recording medium. Thereby, the speed conveyed with the hot roll 42 and the platen roll 45 can be controlled independently. Here, in order to reduce the size of the apparatus, it is preferable to reduce the speed of conveyance by the heat roll 42 and to increase the speed of conveyance by the platen roll 45.

  In the image processing method of the present invention, variable energy is applied to form and erase an image on a reversible thermosensitive recording medium. At this time, it is preferable to change the energy by changing the speed at which the reversible thermosensitive recording medium is conveyed. Thereby, the defect of coloring and decoloring between parts with different heat capacities can be improved. In addition, since color development and decoloring can be performed efficiently, the image processing apparatus can be reduced in size. At this time, the ratio of the speed at which the portion of the reversible thermosensitive recording medium provided with the information processing member to the speed at which the portion of the reversible thermosensitive recording medium provided with the information processing member is transported is 0. It is preferable that it is 1 or more and 1 or less. When this ratio is less than 0.1, the support is deformed, and when it is more than 1, coloring and decoloring defects occur in portions having different heat capacities. Note that the speed at which the reversible thermosensitive recording medium is conveyed can be changed by performing recognition using a sensor that reads the thickness, a sensor that reads the information processing member, or the like.

  In the image processing method of the present invention, it is preferable to change the energy by changing the temperature of the heat source to which the energy is applied. Thereby, the defect of coloring and decoloring between parts with different heat capacities can be improved. At this time, when energy is applied to the portion of the reversible thermosensitive recording medium provided with the information processing member with respect to the temperature of the heat source when the energy is applied to the portion of the reversible thermosensitive recording medium not provided with the information processing member. The temperature ratio of the heat source is preferably 1 or more and 1.6 or less. When this ratio is less than 1, coloring and decoloring defects occur between portions having different heat capacities, and when it is greater than 1.6, the support is deformed. Note that the temperature of the heat source can be changed by recognizing the reversible thermosensitive recording medium with a sensor that reads the thickness, a sensor that reads the information processing member, or the like.

  In consideration of the durability of the reversible thermosensitive recording medium, when the temperature of the reversible thermosensitive recording medium from which the image has been erased is high, the energy given when forming the image is lowered, and the reversible thermosensitive recording from which the image is erased is performed. When the temperature of the medium is low, it is preferable to increase the energy applied when forming an image. Examples of a method for controlling the energy applied to the reversible thermosensitive recording medium include a method of recognizing the operation of the heat roll, the temperature of the reversible thermosensitive recording medium, and the like.

  In the image processing method of the present invention, energy is applied to a portion of the reversible thermosensitive recording medium where the information processing member is provided, and then energy is applied to a portion of the reversible thermosensitive recording medium where the information processing member is not provided. Is preferred. As a result, the temperature of the thermal head is set to a high temperature, an image is formed on the portion where the information processing member is previously provided, and the information processing member is not provided in the thermal head whose temperature has been reduced due to energy consumption. Form an image on the part and set the temperature of the heat roll to a high temperature, erase the image of the part previously provided with the information processing member, and use the heat roll whose temperature has dropped due to energy consumption. It is possible to erase an image of a portion where no is provided, and the energy of the heat source can be effectively utilized, and a simple type image processing apparatus can be provided.

All parts in this example are parts by weight, and this example is merely illustrative of the present invention, and the present invention is not limited by these examples.
