Summary of the Invention

Problems to be Solved by the Invention

[0005] The translucent substrates mentioned above can sometimes have excessive gloss. In this case, when printed materials are attached, the gloss may not blend in with the surroundings and may appear out of place. Furthermore, if a surface protective layer containing a matting agent is applied to the translucent substrate, the occurrence of the gloss can be suppressed, making it possible to blend the printed materials with the surroundings. However, when a surface protective layer containing a matting agent is applied to a translucent substrate, the image seen through the translucent substrate may become cloudy, and the image may not be displayed clearly.

[0006] This disclosure aims to provide printed materials and display devices that can suppress gloss and display images clearly. [Means for solving the problem]

[0007] (1) The printed material relating to this disclosure is a printed material that transmits light from a light source. The printed material comprises a light-transmitting substrate, a pattern printing layer provided on one surface of the light-transmitting substrate, and a surface protection layer provided on the surface of the light-transmitting substrate opposite to the surface on which the pattern printing layer is provided. The surface protection layer has a first recess that is recessed on the surface facing away from the light-transmitting substrate.

[0008] This printed material comprises a pattern printing layer, a translucent substrate, and a surface protection layer. The pattern printing layer is provided on one side of the translucent substrate. The surface protection layer is provided on the side of the translucent substrate opposite to the side on which the pattern printing layer is provided. By having a surface protection layer, this printed material can suppress gloss and blend in with its surroundings. The surface protection layer has a first recess that is indented on the side facing away from the translucent substrate. Because the surface protection layer has the first recess, the amount of matting agent contained in the surface protection layer can be reduced, making it less likely to cause clouding and allowing the image to be clearly displayed by light from a light source.

[0009] (2) In (1) above, the translucent substrate may have a second recess that is recessed on the side facing away from the pattern printing layer and is located on the light source side when viewed from the first recess. In this case, the first recess is located on the side of the second recess of the translucent substrate that is opposite to the light source. By having the surface protective layer have the first recess and the translucent substrate have the second recess, it is possible to make it less likely for the image to become cloudy due to light from the light source.

[0010] (3) In (1) or (2) above, the printed material may have multiple translucent substrates. The multiple translucent substrates may be a first translucent substrate located between the surface protective layer and the pattern printing layer, and a second translucent substrate located between the first translucent substrate and the light source. In this case, the first translucent substrate is placed between the surface protective layer and the pattern printing layer, and the second translucent substrate is placed between the first translucent substrate and the light source. By providing multiple translucent substrates in this way, the unevenness of the printed material can be reduced.

[0011] (4) In (3) above, the glass transition temperature of the first translucent substrate may be lower than the glass transition temperature of the second translucent substrate. In this case, because the glass transition temperature of the first translucent substrate located between the surface protective layer and the pattern printing layer is lower than that of the second translucent substrate, a recess can be formed in the first translucent substrate by heat, and deformation of the second translucent substrate can be prevented. Therefore, the aforementioned first recess can be easily formed, and the manufacture of printed materials can be easily carried out.

[0012] (5) In any of (1) to (4) above, the pattern printing layer may have a first color pattern layer provided on one surface of a translucent substrate and composed of a plurality of first color dots, and a second color pattern layer provided on the first color pattern layer and composed of a plurality of second color dots. Each of the plurality of first color dots may include a first color binder and a plurality of first color pigment chips dispersed inside the first color binder. Each of the plurality of second color dots may include a second color binder and a plurality of second color pigment chips dispersed inside the second color binder. Either the plurality of first color pigment chips or the plurality of second color pigment chips may be a plurality of first interference pigments of different colors that each generate different first interference light. The other of the multiple first-color pigment chips and the multiple second-color pigment chips may be a second interference pigment that generates a monochromatic second interference light different from the color mixing shown by the multiple first interference pigments, and the multiple first interference lights and the second interference lights may be additively mixed.

[0013] (6) In any of (1) to (5) above, the printed material may further comprise a white pattern layer provided on the second color pattern layer and composed of a plurality of silver dots. Each of the plurality of silver dots may include a silver binder and a plurality of silver pigment chips dispersed inside the silver binder.

[0014] (7) In any of (1) to (6) above, the printed material may further comprise a transparent smoke printing layer provided on the outermost surface opposite to the translucent substrate relative to the image printing layer.

[0015] (8) In any of (1) to (7) above, the first interference pigment and the second interference pigment may each contain titanium dioxide-coated mica with a particle size of 25 μm or more and 60 μm or less.

[0016] (9) In any of the above (1) to (8), the content rate of the plurality of first-color pigment chips may be within the range of 0.5 parts by weight or more and 20 parts by weight or less when the binder for the first color is 100 parts by weight, and the content rate of the plurality of second-color pigment chips may be within the range of 0.5 parts by weight or more and 20 parts by weight or less when the binder for the second color is 100 parts by weight.

[0017] (10) The light-transmissive substrate may be composed of either a biomass raw material or a recycled raw material. In this case, when producing the light-transmissive substrate, a biomass raw material or a recycled raw material with a low environmental impact can be used.

[0018] (11) The display device according to the present disclosure includes the above-described printed matter and a light source. Since this display device includes the above-described printed matter, the same effects as described above can be obtained from this display device.

[0019] (12) In the above (11), the light source may be a display device.

Advantages of the Invention

Brief Description of the Drawings

[0021] [Figure 1] FIG. 1 is a diagram schematically showing a printed matter and a display device according to an embodiment. [Figure 2] FIG. 2 is a diagram schematically showing a printed matter and a display device according to another embodiment.

Embodiments for Carrying Out the Invention

[0022] Hereinafter, embodiments of a printed matter and a display device according to the present disclosure will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are denoted by the same reference numerals, and redundant descriptions are omitted as appropriate. The drawings may be drawn with some parts simplified or exaggerated for ease of understanding, and dimensional ratios and the like are not limited to those described in the drawings.

[0023] (First Embodiment) FIG. 1 is a cross-sectional view schematically showing a display device according to the first embodiment. As shown in FIG. 1, as an example, a display device 10 includes a printed matter 1 and a light source 11. The printed matter 1 is a sheet for expressing a pattern. The printed matter 1 includes, for example, a pattern printing layer 2, a translucent base material 3, and a surface protection layer 4. The printed matter 1 is disposed at a position facing the light source 11. The printed matter 1 is provided in front of the light source 11 (between the viewer and the light source 11, above in FIG. 1).

[0024] The printed matter 1 transmits the light L from the light source 11. The light source 11 is, for example, a display device. The light source 11 has a power supply, and the power supply can be switched between ON and OFF. As an example, the light source 11 exhibits black when the power supply is OFF, that is, when it is not irradiating the light L. The printed matter 1 has, for example, total light transmittance. For this reason, when the power supply of the light source 11 is ON, that is, when the light source 11 is irradiating the light L, the viewer can visually recognize the light from the light source 11 that has passed through the printed matter 1. When the power supply of the light source 11 is OFF, the viewer can visually recognize the pattern expressed by the printed matter 1.

[0025] The visible light transmittance of the printed matter 1 may be, for example, 10% or more and 70% or less. By the visible light transmittance of the printed matter 1 being 10% or more, the light L from the light source 11 can be easily passed through the printed matter 1. By the visible light transmittance of the printed matter 1 being 70% or less, the pattern of the pattern printing layer 2 can be clearly displayed. The transmittance means, for example, a value obtained by measuring the transmittance using a spectrophotometer (for example, spectrophotometer UV-2100 manufactured by Shimadzu Corporation).

[0026] The pattern printing layer 2 is provided on one surface 3b of the translucent substrate 3. The pattern printing layer 2 is located between the light source 11 and the translucent substrate 3. The pattern printing layer 2 is the layer that represents the pattern of the printed material 1. The pattern on the pattern printing layer 2 is the pattern that appears on the surface of the printed material 1 when the power to the light source 11 is OFF (when the light source 11 is not irradiating with light L), and is, for example, a wood grain pattern, a stone pattern, or an abstract pattern.

[0027] The method for forming the pattern printing layer 2 is not particularly limited, and it can be formed on the translucent substrate 3 by, for example, inkjet printing, screen printing, gravure printing, or offset printing. The thickness of the pattern printing layer 2 is not particularly limited, but it is preferably 1 μm or more and 15 μm or less. As an example, the pattern printing layer 2 may contain a curing agent. In this case, the heat resistance and adhesion of the pattern printing layer 2 can be improved.

[0028] The translucent substrate 3 must be a substrate that transmits visible light and is therefore transparent. The translucent substrate 3 is, for example, made of a transparent resin. The transparent resin may be, for example, polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polycarbonate (PC), polyamide (PA), or acrylic resin (PMMA). The thickness of the translucent substrate 3 is, for example, 25 μm or more and 250 μm or less.

[0029] The surface protection layer 4 is provided on the surface 3c of the translucent substrate 3 opposite to the surface 3b on which the pattern printing layer 2 is provided. The surface protection layer 4 is provided on the surface side of the translucent substrate 3 (opposite side from the pattern printing layer 2). The surface protection layer 4 is also called a coating layer (topcoat layer). The surface protection layer 4 is provided to ensure the weather resistance of the printed material 1, etc.

[0030] The surface protection layer 4 is made of resin. For example, the surface protection layer 4 is composed of an acrylic resin. For example, the surface protection layer 4 may contain a matting agent. For example, the matting agent is composed of silica (silicon dioxide). The printed material 1 exhibits the effect of reducing gloss by having the surface protection layer 4. For example, the surface protection layer 4 is thinner than the translucent substrate 3. For example, the thickness of the surface protection layer 4 is 10 μm or less.

[0031] The printed material 1 has, for example, a plurality of translucent substrates 3. For example, the plurality of translucent substrates 3 include a first translucent substrate 3A located between the surface protective layer 4 and the pattern printing layer 2, and a second translucent substrate 3B located between the first translucent substrate 3A and the light source 11. In this embodiment, the second translucent substrate 3B is located between the first translucent substrate 3A and the pattern printing layer 2.

[0032] The material of the first translucent substrate 3A is different from, for example, the material of the second translucent substrate 3B. For example, the glass transition temperature of the first translucent substrate 3A is lower than that of the second translucent substrate 3B. Therefore, when heated, the first translucent substrate 3A is more easily deformed (softened) than the second translucent substrate 3B.

[0033] For example, the first translucent substrate 3A is made of PP or PE, and the second translucent substrate 3B is made of PET, PBT, or PC. As an example, the first translucent substrate 3A is made of PP, and the second translucent substrate 3B is made of PET. For example, at least one of the first translucent substrate 3A and the second translucent substrate 3B is made of either biomass raw materials or recycled raw materials.

[0034] The surface protective layer 4 has a first recess 4c that is recessed on the surface 4b facing away from the translucent substrate 3. In a cross-section extending along the thickness direction (vertical direction in Figure 1) of the surface protective layer 4, the first recess 4c is, for example, V-shaped. However, the shape of the first recess 4c in this cross-section is not limited to a V-shape, but may be U-shaped or rectangular, and can be changed as appropriate.

[0035] For example, the surface protection layer 4 has a plurality of first recesses 4c. For example, the plurality of first recesses 4c are dispersed in the surface protection layer 4. As an example, the plurality of first recesses 4c are dispersed substantially evenly in the surface protection layer 4. "The plurality of recesses (first recesses 4c or second recesses 3d described later) are dispersed substantially evenly" means that the recesses are evenly distributed, and this includes, for example, a state in which the recesses are arranged symmetrically to one another, a state in which the recesses are arranged in a grid pattern, a state in which the recesses are arranged in a staggered pattern, or a state in which the recesses are dispersed in a concentric pattern. However, the arrangement of the recesses is not particularly limited. The arrangement of the plurality of first recesses 4c may be adjusted depending on the configuration of the pattern printing layer 2.

[0036] For example, the depth D of the first recess 4c is 3 μm or more and 30 μm or less. The depth D of the first recess 4c refers to the length in the thickness direction of the surface protective layer 4 from the surface 4b facing away from the translucent substrate 3 of the surface protective layer 4 to the innermost part of the first recess 4c. By having a depth D of 3 μm or more, the gloss is reduced without adding a large amount of matting agent to the surface protective layer, and because the amount of matting agent added to the surface protective layer is small, the image illuminated by the light source 11 is less likely to become cloudy. By having a depth D of 30 μm or less, it is possible to prevent the first recess 4c from being too deep, which would make it difficult to see the image illuminated by the light source 11.

[0037] For example, the thickness of the surface protection layer 4 in the first recess 4c is thinner than the thickness of the surface protection layer 4 in the parts other than the first recess 4c. However, the thickness of the surface protection layer 4 in the first recess 4c may be about the same as the thickness of the surface protection layer 4 in the parts other than the first recess 4c, and is not particularly limited.

[0038] The translucent substrate 3 has a second recess 3d on the surface 3c facing away from the pattern printing layer 2, where the first recess 4c is located. In this embodiment, the first translucent substrate 3A has the second recess 3d. In a cross-section extending along the thickness direction (vertical direction in Figure 1) of the translucent substrate 3, the second recess 3d is, for example, V-shaped. However, the shape of the second recess 3d in this cross-section can be changed as appropriate, similar to the first recess 4c described above. For example, the translucent substrate 3 has a plurality of second recesses 3d. For example, the plurality of second recesses 3d are dispersed in the translucent substrate 3. As an example, the plurality of second recesses 3d are dispersed substantially evenly in the translucent substrate 3.

[0039] For example, the depth of the second recess 3d is approximately the same as the depth D of the first recess 4c. The depth of the second recess 3d refers to the length in the thickness direction of the translucent substrate 3 from the surface 3c facing away from the pattern printing layer 2 of the translucent substrate 3 to the innermost part of the second recess 3d. For example, the thickness of the translucent substrate 3 in the second recess 3d is thinner than the thickness of the translucent substrate 3 in the parts other than the second recess 3d.

[0040] Furthermore, the second translucent substrate 3B and the pattern printing layer 2 do not have recesses corresponding to the first recess 4c and the second recess 3d. That is, the second translucent substrate 3B and the pattern printing layer 2 are flat. By having, for example, a flat second translucent substrate 3B, the overall unevenness of the printed material 1 can be reduced.

[0041] Next, an example of a method for manufacturing the printed material 1 according to this embodiment will be described. First, the first translucent substrate 3A is laminated onto the second translucent substrate 3B (step of laminating the first translucent substrate onto the second translucent substrate). Then, the translucent substrate 3 (first translucent substrate 3A) is subjected to thermal embossing to form a plurality of second recesses 3d on the translucent substrate 3 (step of forming the second recesses).

[0042] In this case, because the glass transition temperature of the first translucent substrate 3A is lower than that of the second translucent substrate 3B, a second recess 3d is formed in the first translucent substrate 3A due to heat, while no recess is formed in the second translucent substrate 3B. In other words, the first translucent substrate 3A deforms due to heat and the second recess 3d is formed, while the second translucent substrate 3B does not deform.

[0043] Next, a surface protective layer 4 is applied to the translucent substrate 3 (step of applying the surface protective layer). At this time, the surface protective layer 4 is applied to the second recess 3d of the first translucent substrate 3A, thereby forming the first recess 4c (step of forming the first recess). Subsequently, a pattern printing layer 2 is formed on the second translucent substrate 3B by printing (step of forming the pattern printing layer). After these steps, the series of steps for manufacturing the printed material 1 is completed.

[0044] Next, the effects obtained from the printed material 1 and display device 10 according to this embodiment will be described. The printed material 1 and display device 10 have a pattern printing layer 2, a translucent substrate 3, and a surface protection layer 4. The pattern printing layer 2 is provided on one surface 3b of the translucent substrate 3. The surface protection layer 4 is provided on the surface 3c of the translucent substrate 3 opposite to the surface 3b on which the pattern printing layer 2 is provided. By having the surface protection layer 4, the printed material 1 can suppress the occurrence of gloss and harmonize with its surroundings. The surface protection layer 4 has a first recess 4c that is recessed on the surface 4b facing away from the translucent substrate 3. Because the surface protection layer 4 has the first recess 4c, the amount of matting agent contained in the surface protection layer 4 can be reduced, making it less likely for clouding to occur and allowing the image from the light source L of the light source 11 to be displayed clearly.

[0045] As described above, the translucent substrate 3 may have a recess on the surface 3c facing away from the pattern printing layer 2 and a second recess 3d located on the light source 11 side when viewed from the first recess 4c. In this case, the first recess 4c is located on the side of the second recess 3d of the translucent substrate 3 that is opposite to the light source 11. By having the surface protective layer 4 have the first recess 4c and the translucent substrate 3 have the second recess 3d, it is possible to make it less likely for the image to become cloudy due to the light L from the light source 11.

[0046] As mentioned above, the printed material 1 may include a plurality of translucent substrates 3. The plurality of translucent substrates 3 may be a first translucent substrate 3A located between the surface protective layer 4 and the pattern printing layer 2, and a second translucent substrate 3B located between the first translucent substrate 3A and the light source 11. In this case, the first translucent substrate 3A is placed between the surface protective layer 4 and the pattern printing layer 2, and the second translucent substrate 3B is placed between the first translucent substrate 3A and the light source 11. By providing a plurality of translucent substrates 3, the overall unevenness of the printed material 1 can be reduced.

[0047] As mentioned above, the glass transition temperature of the first translucent substrate 3A may be lower than that of the second translucent substrate 3B. In this case, because the glass transition temperature of the first translucent substrate 3A, which is located between the surface protective layer 4 and the pattern printing layer 2, is lower than that of the second translucent substrate 3B, the second recess 3d can be formed in the first translucent substrate 3A by heat, and deformation of the second translucent substrate 3B can be prevented. Therefore, the second recess 3d and the first recess 4c can be easily formed, and the printed material 1 can be easily manufactured.

[0048] As mentioned above, the first translucent substrate 3A and the second translucent substrate 3B may be composed of either biomass raw materials or recycled raw materials. In this case, when producing the first translucent substrate 3A and the second translucent substrate 3B, biomass raw materials or recycled raw materials with a low environmental impact can be used.

[0049] Furthermore, both the first translucent substrate 3A and the second translucent substrate 3B may be composed of either biomass raw materials or recycled raw materials, or only one of the first translucent substrate 3A or the second translucent substrate 3B may be composed of either biomass raw materials or recycled raw materials. In addition, as an example, when Toyo Sewing recycled double-sided easy-adhesion PET (A065-50μm) was used for the second translucent substrate 3B, it was confirmed that there were no problems regarding the sharpness of the transmitted image.

[0050] (Second Embodiment) Next, the printed material and display device according to the second embodiment will be described with reference to Figure 2. Some of the configurations of the printed material and display device according to the second embodiment are the same as some of the configurations of the printed material 1 and display device 10 described above. Therefore, in the following, explanations that overlap with the descriptions of the printed material 1 and display device 10 described above will be omitted as appropriate, and the same reference numerals will be used.

[0051] As shown in Figure 2, the display device 10A comprises a printed material 1A and a light source 11. In the printed material 1 described above, the first translucent substrate 3A and the second translucent substrate 3B were in contact with each other, whereas in printed material 1A, the first translucent substrate 3A and the second translucent substrate 3B are separated from each other. Printed material 1A differs from printed material 1 in that a pattern printing layer 2 is placed between the first translucent substrate 3A and the second translucent substrate 3B. In printed material 1A, the second translucent substrate 3B, the pattern printing layer 2, the first translucent substrate 3A, and the surface protection layer 4 are arranged in this order from the light source 11 side.

[0052] For example, in printed material 1A, the first translucent substrate 3A is made of PP, and the second translucent substrate 3B is made of PET. However, in printed material 1A, both the first translucent substrate 3A and the second translucent substrate 3B may be made of PP. Thus, the materials of the first translucent substrate 3A and the second translucent substrate 3B can be changed as appropriate.

[0053] An example of a manufacturing method for printed material 1A will be described. First, a pattern printing layer 2 is formed on the second translucent substrate 3B by printing (step of forming the pattern printing layer). Meanwhile, the first translucent substrate 3A is subjected to thermal embossing to form a plurality of second recesses 3d on the first translucent substrate 3A (step of forming the second recesses).

[0054] A surface protective layer 4 is applied to the first translucent substrate 3A to form a first recess 4c (steps of applying the surface protective layer and forming the first recess). Then, the first translucent substrate 3A with the surface protective layer 4 applied is laminated to the pattern printing layer 2 formed on the second translucent substrate 3B (step of laminating the first translucent substrate). After these steps, the printed material 1A is completed.

[0055] As described above, in the display device 10A and printed material 1A, the surface protective layer 4 has a first recess 4c that is recessed on the surface 4b facing away from the translucent substrate 3. Therefore, in the display device 10A and printed material 1A, the amount of matting agent contained in the surface protective layer 4 can be reduced because the surface protective layer 4 has the first recess 4c. As a result, clouding is less likely to occur, and images from the light source L of the light source 11 can be displayed clearly. Thus, the display device 10A and printed material 1A have the same effects as the display device 10 and printed material 1 described above.

[0056] The various embodiments of the printed material and display device described herein have been explained above. However, the printed material and display device described herein are not limited to the embodiments described above and may be modified within the scope of the gist described in the claims. That is, the configuration, shape, size (thickness), material, number, and arrangement of each part of the printed material and display device can be appropriately changed within the scope of the gist described above.

[0057] For example, the pattern printing layer may have a first-color pattern layer provided on one surface of a translucent substrate and composed of a plurality of first-color dots, and a second-color pattern layer provided on the first-color pattern layer and composed of a plurality of second-color dots. Each of the plurality of first-color dots may include a first-color binder and a plurality of first-color pigment chips dispersed inside the first-color binder. Each of the plurality of second-color dots may include a second-color binder and a plurality of second-color pigment chips dispersed inside the second-color binder. Either the plurality of first-color pigment chips or the plurality of second-color pigment chips may be a plurality of first interference pigments of multiple colors, each generating different first interference light. The other of the plurality of first-color pigment chips or the plurality of second-color pigment chips may be a second interference pigment that generates a single-color second interference light different from the color mixing shown by the plurality of first interference pigments, and the plurality of first interference light and the second interference light may be additively mixed.

[0058] The printed material may further comprise a white pattern layer, which is provided on top of the second color pattern layer and consists of multiple silver dots. Each of the multiple silver dots may contain a silver binder and multiple silver pigment chips dispersed within the silver binder.

[0059] The printed material may further include a translucent smoke printing layer provided on the outermost surface opposite to the translucent substrate relative to the image printing layer.

[0060] Each of the first interference pigment and the second interference pigment may contain titanium dioxide-coated mica with a particle size of 25 μm or more and 60 μm or less.

[0061] The content of multiple first-color pigment chips may be within the range of 0.5 parts by weight or more and 20 parts by weight or less, when the first-color binder is 100 parts by weight, and the content of multiple second-color pigment chips may be within the range of 0.5 parts by weight or more and 20 parts by weight or less, when the second-color binder is 100 parts by weight.

[0062] For example, the embodiment described above described a printed material 1 having two translucent substrates 3 (a first translucent substrate 3A and a second translucent substrate 3B). However, the number of translucent substrates in the printed material may be one or three or more, and can be changed as appropriate. For example, the printed material may have two first translucent substrates 3A, and the two first translucent substrates 3A may be made of PP.

[0063] The material of the first translucent substrate 3A may be the same as the material of the second translucent substrate 3B. Alternatively, the printed material may consist of the first translucent substrate 3A made of PP, the first translucent substrate 3A made of PP, and the second translucent substrate 3B made of PET, arranged in this order.

[0064] In the embodiments described above, a printed material 1 was described in which the surface protective layer 4 has a first recess 4c and the translucent substrate 3 (first translucent substrate 3A) has a second recess 3d. However, a printed material may also exist in which the surface protective layer 4 has a first recess 4c and the translucent substrate 3 does not have a second recess 3d. That is, the translucent substrate does not have recesses, and only the surface protective layer may have recesses. In this case, the surface protective layer is thicker than the surface protective layer 4 described above and is composed of, for example, multiple gravure printing layers. Thus, the configurations of the translucent substrate and the surface protective layer can also be changed as appropriate.

[0065] Furthermore, regarding the display device, the light source may be a display device. The display device may be an LED, liquid crystal, organic EL, etc., and if it has a local dimming function, the image can be made sharper. [Explanation of Symbols]
