[First Embodiment]
FIG. 1 is a plan view showing a printed matter 1 according to the first embodiment of the present invention. FIG. 2 is a schematic cross-sectional view of the printed material 1 taken along the line II-II in FIG. FIG. 3 is a schematic sectional view showing the ink ribbon 40 of the first embodiment. FIG. 4 is a schematic cross-sectional view showing a method for manufacturing the printed matter 1 of the first embodiment, FIG. 4A is a schematic cross-sectional view showing a first step, and FIG. 4B is a second step. FIG.

  As shown in FIGS. 1 and 2, the printed material 1 of the present embodiment includes an ink cured material 21 and a metallic ink cured material 23 printed on one surface (Z1 direction) of a sheet-shaped print medium 11. The image is viewed through the print medium 11 from the other surface (Z2 direction) of the medium 11.

  The print medium 11 is a light-transmitting synthetic resin, and is preferably transparent to visible light. Note that, in this specification, “transparent” means high transmittance, and is not limited to an ideal state in which there is no absorption or scattering of light. The print medium 11 is used, for example, as a part of a member constituting an appearance of a portable electronic device. In this case, the resin material is selected in consideration of other physical properties. For example, polycarbonate (PC) and polymethyl methacrylate (PMMA) are preferably used. Further, in FIG. 1, the print medium 11 is formed in a rectangular shape in plan view, but is not limited to this. In FIG. 2, one side (Z1 direction) side and the other side (Z2 The (direction) side is configured to have a flat shape, but is not limited thereto, and may have a shape including a curved surface.

  As shown in FIG. 2, the ink cured material 21 has a second ink cured layer 21b laminated on a first ink cured layer 21a, and a third ink cured layer 21b on the second ink cured layer 21b. 21c are stacked. The first ink cured layer 21a is formed by adding the pigment PG to the binder resin BR, and the third ink cured layer 21c is formed by adding the transparent fine particles TG to the binder resin BR. The second ink cured layer 21b contains transparent fine particles TG as a main component and is held by a binder resin BR. In FIG. 2, the boundaries between the layers are clearly shown as a schematic diagram. However, in reality, if the binder resin BR is the same, it is recognized only as a difference in the distribution between the pigment PG and the transparent fine particles TG. .

  The binder resin BR is a translucent and thermoplastic synthetic resin, and is preferably transparent to visible light. As the thermoplastic synthetic resin, an acrylic synthetic resin such as an acrylate polymer is preferable. Further, an olefin-based synthetic resin such as an ethylene-vinyl acetate copolymer or another thermoplastic synthetic resin may be used. In order to adjust the melt viscosity, a plurality of thermoplastic synthetic resins may be mixed, or various waxes may be blended.

The pigment PG is added to absorb and reflect a part of the visible light incident through the print medium 11 to obtain a desired color tone. The transparent fine particles TG are inorganic pigments that are transparent to visible light, and are added to make the binder resin BR harder than the binder resin BR alone. For example, fine particles of SiO ₂ or TiO _{2 having} a particle size of 50 nm to 200 nm can be used. When the transparent fine particles TG are used as the pigment PG, the first ink cured layer 21a that is colorless with respect to visible light can be obtained. When adjusting the first ink cured layer 21a to have a desired color tone, a coloring pigment is used as the pigment PG. It is known that when a coloring pigment is added as the pigment PG, the state becomes harder than the state of the binder resin BR alone.

  As shown in FIG. 2, the metallic ink cured material 23 is disposed so as to cover the third ink cured layer 21c of the ink cured material 21. The cured metallic ink 23 has a thin metal film obtained by evaporating a metal material on a translucent and thermoplastic synthetic resin, reflects visible light, and hardly transmits it. For example, a metal material such as tin or aluminum is used, and a metal film having a thickness of 10 nm to 100 nm is formed. The cured metallic ink 23 preferably has an adhesive layer (not shown) made of a thermoplastic synthetic resin on the interface side with the cured ink 21.

  When the printed matter 1 of the present embodiment is viewed from the other surface (Z2 direction) side of the print medium 11 through the print medium 11, the incident visible light is reflected by the metallic ink cured matter 23, and the cured ink 21 The arranged area is recognized as an ink image having a desired color tone.

  When a desired color tone is not a dark color but a light color tone is required, the cured ink 21 has a smaller amount of the pigment PG added to the first cured ink layer 21a. For this reason, the hardness of the binder resin BR is not sufficient only with the first ink cured layer 21a, and particularly, the binder resin BR easily flows in a heated state. In the present embodiment, since the cured ink 21 has the second cured ink layer 21b containing the transparent fine particles TG as a main component, even when the hardness of the first cured ink layer 21a is not high. Is hardened by the second ink cured layer 21b. Accordingly, even in the configuration in which the metallic ink cured product 23 is laminated on the highly transparent ink cured product 21, the flow of the first ink cured layer 21 a is suppressed, and the metallic ink cured product 23 covering the ink cured product 21 is suppressed. Are disposed in a desired state without being distorted. Furthermore, since the third ink cured layer 21c laminated on the second ink cured layer 21b contains the binder resin BR, the ink cured product 21 in the present embodiment has an adhesive property with the metallic ink cured product 23. Can be secured. In the third ink cured layer 21c, since the transparent fine particles TG are added to the binder resin BR, the amount of the transparent fine particles TG can be added in a range where both hardness and adhesion are compatible. The third ink cured layer 21c in the present embodiment has a lower hardness than the second ink cured layer 21b containing the transparent fine particles TG as a main component, but is compared with the first ink cured layer 21a to which less pigment PG is added. High hardness. In addition, since the second ink cured layer 21b and the third ink cured layer 21c do not contain a coloring pigment other than the transparent fine particles TG, there is no concern that the color tone of the first ink cured layer 21a is affected, and the hardened layer is hardened. It can be provided with both adhesiveness. For this reason, even if the configuration is such that the metallic ink cured material 23 is laminated on the highly transparent ink cured material 21, the problem of a dull appearance does not occur. Therefore, when the image is viewed through the print medium 11 from the other surface (Z2 direction) side of the print medium 11, the gloss is uniform and the appearance is good. When the metallic ink cured product 23 is laminated on the highly transparent ink cured product 21, various metallic shades (for example, pink gold) can be realized.

  In the printed matter 1 of the present embodiment, the cured ink 21 is formed by thermal transfer printing using the ink ribbon 40 shown in FIG.

  As shown in FIG. 3, the ink ribbon 40 includes a third ink layer 43, a second ink layer 42, and a first ink layer 41 on a surface of a film 46 made of polyethylene terephthalate (PET) or the like. They are stacked in this order. Preferably, the thickness of the film 46 is 2 to 10 μm, the thickness of the third ink layer 43 is 0.2 to 0.5 μm, the thickness of the second ink layer 42 is 0.05 to 0.2 μm, The thickness of the first ink layer 41 is 0.2 to 0.5 μm. The ink ribbon 40 is formed in an elongated shape, and is wound in a roll shape.

  The first ink layer 41 is an ink layer in which a pigment PG corresponding to a desired color tone is added to a binder resin BR. The third ink layer 43 is an ink layer in which transparent fine particles TG are added to a binder resin BR. The second ink layer 42 is an ink layer made of transparent fine particles TG and held by being sandwiched between the first ink layer 41 and the third ink layer 43. In FIG. 3, the boundaries between the layers are clearly shown as a schematic diagram. However, in reality, if the binder resin BR is the same, it is recognized only as a difference in the distribution state between the pigment PG and the transparent fine particles TG. .

  The method of manufacturing the printed matter 1 according to the present embodiment includes a first step of performing thermal transfer printing of a desired ink image on one surface (Z1 direction) of the print medium 11 as shown in FIG. 4A, and FIG. And a second step of performing thermal transfer printing of the metallic ink image as shown in FIG.

  In the first step, as shown in FIG. 4A, a desired ink image is thermally transferred and printed on one surface (Z1 direction) of the print medium 11 using the ink ribbon 40 shown in FIG. 21 are formed. As shown in FIG. 3, the ink ribbon 40 includes a first ink layer 41 in which a coloring pigment corresponding to a desired color tone is added to a binder resin BR, a second ink layer 42 made of transparent fine particles TG, and a binder. And a third ink layer 43 in which transparent fine particles TG are added to the resin BR. When the ink ribbon 40 is pressed against one surface (Z1 direction) of the print medium 11 and heated from the back side of the film 46, the binder resin BR of the first ink layer 41 adheres to the print medium 11. On the other hand, when the film 46 of the ink ribbon 40 is separated from the print medium 11, the third ink layer 43 and the film 46 separate. As a result, the first ink layer 41, the second ink layer 42, and the third ink layer 43 are subjected to thermal transfer printing on one surface (Z1 direction) side of the print medium 11, and the first ink cured layer 21a, An ink cured product 21 composed of the second ink cured layer 21b and the third ink cured layer 21c is formed. When the ink ribbon 40 is not heated, the binder resin BR of the first ink layer 41 does not adhere, the film 46 does not separate from the third ink layer 43, and the thermal transfer printing is not performed. Thus, by providing the heated area and the non-heated area, a desired ink image can be obtained.

  In the second step, as shown in FIG. 4B, a metallic ink image is subjected to thermal transfer printing using a metallic ink ribbon (not shown) provided with a metal film, and a metallic ink cured product is formed on the ink image. 23 are formed. Metallic ink ribbons are formed by laminating a metallic ink layer having a thin metal film obtained by depositing a metal material on a translucent thermoplastic resin on the surface of a film made of polyethylene terephthalate (PET) or the like. It is. The thickness of the metallic ink layer is 0.5 to 1.5 μm. As in the first step, thermal transfer printing is performed by pressing and heating the metallic ink ribbon. In the present embodiment, the metallic ink image has the same shape as the ink image formed by the cured ink 21, and the cured metallic ink 23 is provided so as to cover the cured ink 21.

  In the present embodiment, in the first step, the second ink layer 42 made of the transparent fine particles TG and the third ink layer 43 in which the transparent fine particles TG are added to the binder resin BR are each provided with a hardening layer and An impact-absorbing layer is formed. For this reason, even if the metallic ink ribbon is heated and subjected to thermal transfer printing in the second step, the cured ink 21 is unlikely to deform, so that the cured metallic ink 23 can be formed stably. Therefore, a desired color tone can be obtained by the first ink layer 41, and the metallic ink cured material 23 covering the ink cured material 21 reflects light, so that the printed matter 1 having uniform gloss and good appearance can be obtained. . The cured metallic ink 23 may cover the cured ink 21 formed by thermal transfer printing using the ink ribbon 40, and may have a region directly thermally transferred to the print medium 11. This makes it possible to simultaneously form a desired color tone ink image region and a region where the metallic tone metallic ink image is directly visible.

The second ink cured layer 21b is laminated on the first ink cured layer 21a.

  According to this configuration, the second ink cured layer 21b mainly composed of the transparent fine particles TG is hardened without changing the color tone of the first ink cured layer 21a. Even with the configuration in which the metallic ink cured products 23 are laminated, the problem of dull appearance does not occur. Therefore, it is possible to provide a printed matter having uniform gloss and good appearance.

  In the printed matter 1 of the present embodiment, the first cured ink layer 21a is obtained by adding the pigment PG to the binder resin BR, and the cured ink 21 is obtained by adding the transparent fine particles TG to the binder resin BR. A third ink cured layer 21c is provided on the second ink cured layer 21b mainly including the transparent fine particles TG.

  According to this configuration, since the third ink cured layer 21c includes the binder resin BR, the adhesion with the metallic ink cured material 23 can be ensured.

  According to this configuration, since the transparent fine particles TG are not added to the first ink cured layer 21a, the second ink cured layer 21b and the third ink cured layer are maintained without impairing the adhesion to the print medium 11. By laminating 21c, the first ink cured layer 21a can be hardened without changing the color tone.

  Further, in the method of manufacturing the printed material 1 according to the present embodiment, the sheet-shaped print medium 11, the cured ink 21 disposed on one surface (Z1 direction) of the print medium 11, and the cured ink 21 are coated.

A second step of forming a metallic ink cured product 23 on the Kutomo ink image.

  According to this configuration, a desired color tone can be obtained from the ink image thermally printed on one surface (Z1 direction) of the print medium 11 by the first ink layer 41 in which the pigment PG is added to the binder resin BR. Since the second ink layer 42 made of the transparent fine particles TG and the third ink layer 43 in which the transparent fine particles TG are added to the binder resin BR form a hardening layer and an impact-absorbing layer, respectively, Thus, a cured metallic ink 23 can be formed. Therefore, a printed matter with uniform gloss and good appearance can be obtained.

  The ink ribbon 40 of the present embodiment includes a first ink layer 41 in which a pigment PG corresponding to a desired color tone is added to a binder resin BR, a second ink layer 42 made of transparent fine particles TG, and a binder resin BR.

  According to this configuration, a desired color tone can be obtained by the first ink layer 41, and a hardened layer can be obtained by the second ink layer 42 made of the transparent fine particles TG.

  In the printed matter 1 of the present embodiment, for example, the ink image formed by the cured ink 21 may be formed into an island shape, and the cured metallic ink 23 may be formed in a region where the cured ink 21 is not present. This makes it possible to obtain a printed matter on which a dot pattern of a desired color tone is printed on a metallic background.

  In the printed matter 1 of the present embodiment, the pigment PG is a color pigment. However, the pigment PG may be transparent fine particles TG. In this case, a printed matter of a metallic color image is obtained. For example, if the ink image formed by the cured ink 21 is made linear and the cured metallic ink 23 is formed in a region where the cured ink 21 is not present, a printed material having a metallic hairline pattern printed thereon can be obtained.

As shown in FIG. 6, the ink ribbon 60 includes a fourth ink layer 61 in which transparent fine particles TG are added to a binder resin BR, a fifth ink layer 62 made of transparent fine particles TG, and a transparent fine particle in the binder resin BR. A sixth ink layer 63 to which TG is added. By pressing the ink ribbon 60 against one surface (Z1 direction) of the print medium 11 on which the ink image has been formed in the first step and heating it from the back side of the film 66, the binder resin of the fourth ink layer 61 is formed. The BR comes into close contact with the cured ink 21 and the print medium 11. On the other hand, when the film 66 of the ink ribbon 60 is separated from the print medium 11, the sixth ink layer 63 and the film 66 are separated. As a result, the fourth ink layer 61, the fifth ink layer 62, and the sixth ink layer 63 are subjected to thermal transfer printing on one surface (Z1 direction) side of the print medium 11, and the fourth ink cured layer 22a and the fourth ink layer The transparent ink cured material 22 including the fifth ink cured layer 22b and the sixth ink cured layer 22c is formed. When the ink ribbon 60 is not heated, the binder resin BR of the fourth ink layer 61 does not adhere, and the film 66 does not separate from the sixth ink layer 63, so that thermal transfer printing is not performed. Thus, by providing the heated region and the non-heated region, a desired transparent ink image can be obtained.

  In the present embodiment, since the second step is performed following the transparent ink image printing step, the second step uses the metallic ink ribbon after the cured ink 21 or the cured transparent ink 22 is formed. Thus, the metallic ink image is thermally transferred and printed to form the cured metallic ink 23. Thus, the cured metallic ink 23 is provided so as to cover the cured ink 21 or the cured transparent ink 22. As shown in FIG. 7C, when the transparent ink cured material 22 is formed by providing an area directly thermally transferred to the print medium 11, the metallic ink image in a metallic tone is directly visible. .

  In a conventional transparent ink ribbon different from the present embodiment, a transparent ink layer is formed only on a binder resin on the surface of a film. When a transparent ink image printed by thermal transfer using the conventional transparent ink ribbon is subjected to thermal transfer printing using a metallic ink ribbon, the hardness of the binder resin is not sufficient, and it flows particularly in a heated state. In some cases, the metallic ink image was distorted. For this reason, when a transparent ink layer consisting of only a binder resin is laminated or arranged on an ink image thermally printed using an ink ribbon to which a coloring pigment is added, the printed matter looks dull. On the other hand, if the transparent fine particles TG are added to the binder resin so as to obtain sufficient hardness, the amount of the transparent fine particles TG increases, and the adhesiveness of the transparent ink layer deteriorates.

  In the present embodiment, the fourth ink layer 61 in which the transparent fine particles TG are added to the binder resin BR, the fifth ink layer 62 made of the transparent fine particles TG, and the sixth ink layer 62 in which the transparent fine particles TG are added to the binder resin BR. Since the thermal transfer printing is performed using the ink ribbon 60 on which the ink layer 63 is laminated, the transparent ink layer can be hardened while maintaining good adhesion. Thus, even if thermal transfer printing is performed on the transparent ink image using the metallic ink ribbon, the image does not look dull as in the related art. Therefore, compared with the printed matter 1 of the first embodiment, the appearance is better and the print quality is improved.

  Hereinafter, effects of the present embodiment will be described.
