Patent No. 7457089

The translucent substrates mentioned above can sometimes have too much gloss. In this case, when a printed matter is applied, the gloss may not blend in with its surroundings and may appear unusual. If a surface protective layer containing a matting agent is provided on the translucent substrate, the occurrence of this gloss can be suppressed, making it possible for the printed matter to blend in with its surroundings. However, if a surface protective layer containing a matting agent is provided on the translucent substrate, the image seen through the translucent substrate may become cloudy, preventing the image from being displayed clearly.

The purpose of this disclosure is to provide printed matter and display devices that can suppress the generation of gloss and display images clearly.

(1) The printed matter according to the present disclosure is a printed matter that transmits light from a light source. The printed matter comprises a translucent substrate, a picture print layer provided on one surface of the translucent substrate, and a surface protection layer provided on the surface of the translucent substrate opposite the surface on which the picture print layer is provided. The surface protection layer has a first recess that is recessed on the surface facing away from the translucent substrate.

This printed matter has a picture print layer, a translucent substrate, and a surface protective layer. The picture print layer is provided on one side of the translucent substrate. The surface protective layer is provided on the side of the translucent substrate opposite the side on which the picture print layer is provided. By having the surface protective layer, this printed matter can suppress the generation of gloss and blend in with its surroundings. The surface protective layer has a first recess that is recessed on the surface facing away from the translucent substrate. By having the first recess in the surface protective layer, the amount of matting agent contained in the surface protective layer can be reduced, making it less likely to cause fogging and allowing the image formed by the light from the light source to be clearly displayed.

(2) In (1) above, the translucent substrate may have a second recess that is recessed in the surface facing away from the picture print 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 surface of the second recess of the translucent substrate opposite the light source. By having the first recess in the surface protection layer and the second recess in the translucent substrate, it is possible to make it less likely for the image to become cloudy due to light from the light source.

(3) In (1) or (2) above, the printed matter may include a plurality of translucent substrates. The plurality of translucent substrates may be a first translucent substrate located between the surface protective layer and the picture printed layer, and a second translucent substrate located between the first translucent substrate and the light source. In this case, the first translucent substrate is disposed between the surface protective layer and the picture printed layer, and the second translucent substrate is disposed between the first translucent substrate and the light source. By providing a plurality of translucent substrates in this manner, the unevenness of the printed matter can be reduced.

(4) In (3) above, the glass transition point of the first translucent substrate may be lower than that of the second translucent substrate. In this case, the glass transition point of the first translucent substrate located between the surface protective layer and the picture print layer is lower than that of the second translucent substrate, so that recesses can be formed in the first translucent substrate by heat and deformation of the second translucent substrate can be prevented. Therefore, the first recesses described above can be easily formed, facilitating the production of printed matter.

(5) In any of (1) to (4) above, the picture printed layer may have a first color pattern layer formed on one surface of the translucent substrate and composed of a plurality of first color dots, and a second color pattern layer formed 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 within 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 within the second color binder. Either the plurality of first color pigment chips or the plurality of second color pigment chips may be a first interference pigment of a plurality of colors that each generate a different first interference light from each other. 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 single color second interference light different from the mixed color exhibited by the multiple first interference pigments, or may be an additive color mixture of the multiple first interference light and the second interference light.

(6) In any of (1) to (5) above, the printed matter may further include a white pattern layer formed 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 within the silver binder.

(7) In any of (1) to (6) above, the printed matter may further include a translucent smoke print layer provided on the outermost surface of the picture print layer on the side opposite the translucent substrate.

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

(9) In any of (1) to (8) above, the content of the multiple first color pigment chips may be in the range of 0.5 parts by weight to 20 parts by weight, where the first color binder is 100 parts by weight, and the content of the multiple second color pigment chips may be in the range of 0.5 parts by weight to 20 parts by weight, where the second color binder is 100 parts by weight.

(10) The translucent substrate may be made from either biomass or recycled materials. In this case, biomass or recycled materials, which have a low environmental impact, can be used to produce the translucent substrate.

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

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

This disclosure reduces the occurrence of gloss, produces a highly aesthetically pleasing printed matter when the display is OFF, and displays a clear image when the display is ON.

FIG. 1 is a diagram schematically illustrating a printed matter and a display device according to an embodiment. FIG. 2 is a diagram schematically illustrating a printed matter and a display device according to another embodiment.

Below, embodiments of printed matter and display devices according to the present disclosure will be described with reference to the drawings. In the description of the drawings, identical or corresponding elements will be given the same reference numerals, and duplicate explanations will be omitted as appropriate. The drawings may be partially simplified or exaggerated to facilitate understanding, and dimensional proportions, etc., are not limited to those shown in the drawings.

(First embodiment)
FIG. 1 is a cross-sectional view that schematically shows a display device according to a first embodiment. As shown in FIG. 1, an example 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 printed layer 2, a light-transmitting substrate 3, and a surface protective layer 4. The printed matter 1 is disposed in a position facing the light source 11. The printed matter 1 is provided in front of the light source 11 (between a viewer and the light source 11, above in FIG. 1 ).

Printed matter 1 transmits light L from light source 11. Light source 11 is, for example, a display device. Light source 11 has a power source that can be switched on and off. As an example, light source 11 appears black when the power is off, i.e., when it is not emitting light L. Printed matter 1 is, for example, fully light transmissive. Therefore, when light source 11 is on, i.e., when light source 11 is emitting light L, the viewer sees the light from light source 11 that has passed through printed matter 1. When light source 11 is off, the viewer sees the image represented by printed matter 1.

The visible light transmittance of the printed matter 1 may be, for example, 10% or more and 70% or less. When the visible light transmittance of the printed matter 1 is 10% or more, light L from the light source 11 can easily pass through the printed matter 1. When the visible light transmittance of the printed matter 1 is 70% or less, the image on the picture printing layer 2 can be displayed clearly. The transmittance refers to the value measured using, for example, a spectrophotometer (e.g., the UV-2100 spectrophotometer manufactured by Shimadzu Corporation).

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 a layer that expresses the pattern of the printed matter 1. The pattern printing layer 2 is a layer on which the pattern expressed by the printed matter 1 is formed. The pattern of the pattern printing layer 2 is a pattern that appears on the surface of the printed matter 1 when the light source 11 is turned off (when the light source 11 is not emitting light L), and is, for example, a wood grain pattern, a stone grain pattern, or an abstract pattern.

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 desirable that it be 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.

The light-transmitting substrate 3 must be a substrate that is transparent to visible light, and is therefore a transparent substrate. The light-transmitting substrate 3 is made of, for example, a transparent resin. Examples of transparent resins include polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polycarbonate (PC), polyamide (PA), or acrylic resin (PMMA). The thickness of the light-transmitting substrate 3 is, for example, 25 μm or more and 250 μm or less.

The surface protective layer 4 is provided on the surface 3c of the translucent substrate 3 opposite the surface 3b on which the picture printed layer 2 is provided. The surface protective layer 4 is provided on the front side of the translucent substrate 3 (the side opposite the picture printed layer 2). The surface protective layer 4 is also called a coating layer (top coat layer). The surface protective layer 4 is provided to ensure the weather resistance of the printed matter 1, etc.

The surface protective layer 4 is made of resin. As an example, the surface protective layer 4 is made of an acrylic resin. For example, the surface protective layer 4 may contain a matting agent. For example, the matting agent is made of silica (silicon dioxide). By providing the surface protective layer 4, the printed matter 1 has the effect of reducing gloss. For example, the surface protective layer 4 is thinner than the translucent substrate 3. For example, the thickness of the surface protective layer 4 is 10 μm or less.

The printed matter 1 has, for example, a plurality of light-transmissive substrates 3. For example, the plurality of light-transmissive substrates 3 are a first light-transmissive substrate 3A located between the surface protective layer 4 and the picture-printed layer 2, and a second light-transmissive substrate 3B located between the first light-transmissive substrate 3A and the light source 11. In this embodiment, the second light-transmissive substrate 3B is located between the first light-transmissive substrate 3A and the picture-printed layer 2.

The material of the first translucent substrate 3A is different from the material of the second translucent substrate 3B, for example. For example, the glass transition point of the first translucent substrate 3A is lower than the glass transition point of the second translucent substrate 3B. Therefore, when heated, the first translucent substrate 3A is more likely to deform (soften) than the second translucent substrate 3B.

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

The surface protective layer 4 has a first recess 4c recessed in the surface 4b facing away from the translucent substrate 3. In a cross section extending along the thickness direction of the surface protective layer 4 (the vertical direction in Figure 1), 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 and may be U-shaped or rectangular, and can be modified as appropriate.

For example, the surface protective layer 4 has a plurality of first recesses 4c. For example, the plurality of first recesses 4c are dispersedly arranged in the surface protective layer 4. As an example, the plurality of first recesses 4c are dispersed approximately evenly in the surface protective layer 4. "A plurality of recesses (first recesses 4c or second recesses 3d described below) are dispersed approximately evenly" refers to a state in which the recesses are evenly arranged, and includes, for example, a state in which the recesses are arranged symmetrically with respect to one another, a state in which the recesses are arranged in a lattice pattern, a state in which the recesses are arranged in a staggered pattern, or a state in which the recesses are dispersed concentrically. 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 type of the picture-printed layer 2.

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 protection layer 4 from the surface 4b of the surface protection layer 4 facing away from the translucent substrate 3 to the innermost part of the first recess 4c. When the depth D is 3 μm or more, the gloss is reduced without adding a large amount of matting agent to the surface protection layer, and since the amount of matting agent added to the surface protection layer is small, the image captured by the light source 11 is less likely to become cloudy. When the depth D is 30 μm or less, the first recess 4c is prevented from being too deep, which would make it difficult to see the image captured by the light source 11.

For example, the thickness of the surface protective layer 4 in the first recess 4c is thinner than the thickness of the surface protective layer 4 in areas other than the first recess 4c. However, the thickness of the surface protective layer 4 in the first recess 4c may be approximately the same as the thickness of the surface protective layer 4 in areas other than the first recess 4c, and is not particularly limited.

The translucent substrate 3 has a second recess 3d that is recessed on the surface 3c facing away from the picture-printed layer 2 and in which 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 of the translucent substrate 3 (the vertical direction in FIG. 1), the second recess 3d is, for example, V-shaped. However, the shape of the second recess 3d in the 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 dispersedly arranged on the translucent substrate 3. As an example, the plurality of second recesses 3d are dispersedly arranged approximately evenly on the translucent substrate 3.

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 of the translucent substrate 3 facing away from the picture-printed layer 2 to the innermost part of the second recess 3d. For example, the thickness of the translucent substrate 3 at the second recess 3d is thinner than the thickness of the translucent substrate 3 in parts other than the second recess 3d.

The second translucent substrate 3B and the picture printed layer 2 do not have recesses corresponding to the first recess 4c and the second recess 3d. The second translucent substrate 3B and the picture printed layer 2 are flat. For example, by having a flat second translucent substrate 3B, the printed matter 1 can reduce the overall sense of unevenness.

An example of a method for manufacturing the printed matter 1 according to this embodiment will now be described. First, the first translucent substrate 3A is laminated onto the second translucent substrate 3B (a step of laminating the first translucent substrate onto the second translucent substrate). Then, the translucent substrate 3 (first translucent substrate 3A) is thermally embossed to form a plurality of second recesses 3d in the translucent substrate 3 (a step of forming second recesses).

At this time, because the glass transition point of the first light-transmitting substrate 3A is lower than that of the second light-transmitting substrate 3B, the heat causes the second recess 3d to be formed in the first light-transmitting substrate 3A, but no recess is formed in the second light-transmitting substrate 3B. The first light-transmitting substrate 3A is deformed by the heat, forming the second recess 3d, while the second light-transmitting substrate 3B does not deform.

A surface protective layer 4 is applied to the translucent substrate 3 (surface protective layer application step). At this time, the surface protective layer 4 is applied to the second recesses 3d of the first translucent substrate 3A, thereby forming first recesses 4c (first recess formation step). After that, a picture printed layer 2 is formed by printing on the second translucent substrate 3B (picture printed layer formation step). Through the above steps, the series of steps in the method for manufacturing the printed matter 1 is completed.

The effects obtained from the printed matter 1 and display device 10 according to this embodiment will now be described. The printed matter 1 and display device 10 have a picture print layer 2, a translucent substrate 3, and a surface protective layer 4. The picture print layer 2 is provided on one surface 3b of the translucent substrate 3. The surface protective layer 4 is provided on the surface 3c of the translucent substrate 3 opposite the surface 3b on which the picture print layer 2 is provided. By having the surface protective layer 4, the printed matter 1 can suppress gloss and blend in with its surroundings. The surface protective layer 4 has a first recess 4c that is recessed on the surface 4b facing away from the translucent substrate 3. By having the first recess 4c in the surface protective layer 4, the amount of matting agent contained in the surface protective layer 4 can be reduced, making it less likely to cause fogging and allowing the image formed by the light L from the light source 11 to be displayed clearly.

The translucent substrate 3 may have a second recess 3d recessed in the surface 3c facing away from the picture-printed layer 2 and 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 surface of the second recess 3d of the translucent substrate 3 opposite the light source 11. By having the surface protection 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.

The printed matter 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 picture printed 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 located between the surface protective layer 4 and the picture printed layer 2, and the second translucent substrate 3B is located between the first translucent substrate 3A and the light source 11. By providing a plurality of translucent substrates 3, the unevenness of the printed matter 1 as a whole can be reduced.

The glass transition point of the first translucent substrate 3A may be lower than that of the second translucent substrate 3B. In this case, because the glass transition point of the first translucent substrate 3A located between the surface protective layer 4 and the picture printed layer 2 is lower than that of the second translucent substrate 3B, the second recesses 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 recesses 3d and the first recesses 4c can be easily formed, facilitating the production of the printed matter 1.

The first translucent substrate 3A and the second translucent substrate 3B may be made from either biomass materials or recycled materials. In this case, biomass materials or recycled materials that have a low environmental impact can be used to manufacture the first translucent substrate 3A and the second translucent substrate 3B.

Both the first translucent substrate 3A and the second translucent substrate 3B may be made from either biomass or recycled materials, or only either the first translucent substrate 3A or the second translucent substrate 3B may be made from either biomass or recycled 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 with the sharpness of the transmitted image.

Second Embodiment
A printed matter and a display device according to a second embodiment will be described with reference to Fig. 2. The configuration of part of the printed matter and the display device according to the second embodiment is the same as the configuration of part of the printed matter 1 and the display device 10 described above. Therefore, in the following, explanations that overlap with the explanations of the printed matter 1 and the display device 10 described above will be omitted as appropriate by assigning the same reference numerals.

As shown in FIG. 2, the display device 10A comprises a printed matter 1A and a light source 11. In the previously described printed matter 1, the first light-transmissive substrate 3A and the second light-transmissive substrate 3B are in contact with each other, whereas in the printed matter 1A, the first light-transmissive substrate 3A and the second light-transmissive substrate 3B are spaced apart. The printed matter 1A differs from the printed matter 1 in that a picture print layer 2 is disposed between the first light-transmissive substrate 3A and the second light-transmissive substrate 3B. In the printed matter 1A, the second light-transmissive substrate 3B, the picture print layer 2, the first light-transmissive substrate 3A, and the surface protection layer 4 are arranged in this order from the light source 11 side.

For example, in printed matter 1A, the first light-transmissive substrate 3A is made of PP, and the second light-transmissive substrate 3B is made of PET. However, in printed matter 1A, both the first light-transmissive substrate 3A and the second light-transmissive substrate 3B may be made of PP. In this way, the materials of the first light-transmissive substrate 3A and the second light-transmissive substrate 3B can be changed as appropriate.

An example of a method for manufacturing the printed matter 1A will now be described. First, a picture print layer 2 is formed by printing on the second light-transmitting substrate 3B (a step of forming a picture print layer). Then, a thermal embossing process is performed on the first light-transmitting substrate 3A to form a plurality of second recesses 3d in the first light-transmitting substrate 3A (a step of forming second recesses).

A surface protective layer 4 is applied to the first translucent substrate 3A to form first recesses 4c (step of applying a surface protective layer, step of forming a first recess). Then, the first translucent substrate 3A with the surface protective layer 4 formed thereon is bonded to the picture printed layer 2 formed on the second translucent substrate 3B (step of bonding the first translucent substrate). Through these steps, the printed matter 1A is completed.

In the display device 10A and the printed matter 1A, the surface protective layer 4 has a first recess 4c recessed in the surface 4b facing away from the light-transmitting substrate 3. In the display device 10A and the printed matter 1A, the surface protective layer 4 has the first recess 4c, which makes it possible to reduce the amount of matting agent contained in the surface protective layer 4. As a result, fogging is less likely to occur, and images formed by light L from the light source 11 can be clearly displayed. In this way, the display device 10A and the printed matter 1A achieve the same effects as the display device 10 and the printed matter 1 described above.

Various embodiments of the printed matter and display device according to the present disclosure have been described. However, the printed matter and display device according to the present disclosure are not limited to the contents of the above-described embodiments, and may be modified within the scope of the gist set forth in the claims. In other words, the configuration, shape, size (thickness), material, number, and arrangement of each part of the printed matter and display device may be modified as appropriate within the scope of the above-described gist.

For example, the picture print layer may include a first color pattern layer formed on one surface of the translucent substrate and composed of a plurality of first color dots, and a second color pattern layer formed 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 within 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 within the second color binder. Either of the plurality of first color pigment chips or the plurality of second color pigment chips may be a first interference pigment of a plurality of colors that respectively generate different first interference lights. 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 monochromatic second interference light different from the mixed color exhibited by the plurality of first interference pigments, and may be an additive color mixture of the plurality of first interference lights and the second interference light.

The printed matter may further include a white pattern layer formed 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 within the silver binder.

The printed matter may further include a translucent smoke print layer provided on the outermost surface of the picture print layer on the side opposite the translucent substrate.

The first interference pigment and the second interference pigment may each contain titanium dioxide-coated mica having a particle size of 25 μm or more and 60 μm or less.

The content of the multiple first color pigment chips may be in the range of 0.5 parts by weight to 20 parts by weight, where the first color binder is 100 parts by weight, and the content of the multiple second color pigment chips may be in the range of 0.5 parts by weight to 20 parts by weight, where the second color binder is 100 parts by weight.

For example, in the above-described embodiment, a printed matter 1 having two light-transmissive substrates 3 (a first light-transmissive substrate 3A and a second light-transmissive substrate 3B) was described. However, the number of light-transmissive substrates the printed matter has may be one or three or more, and can be changed as appropriate. For example, the printed matter may have two first light-transmissive substrates 3A, and the two first light-transmissive substrates 3A may be made of PP.

The material of the first translucent substrate 3A may be the same as the material of the second translucent substrate 3B. The printed matter may also have a first translucent substrate 3A made of PP, a first translucent substrate 3A made of PP, and a second translucent substrate 3B made of PET arranged in this order.

In the above-described embodiment, a printed matter 1 was described in which the surface protective layer 4 has the first recess 4c and the translucent substrate 3 (first translucent substrate 3A) has the second recess 3d. However, the printed matter may also have a surface protective layer 4 that has the first recess 4c and a translucent substrate 3 that does not have the second recess 3d. The translucent substrate may not have a recess, and only the surface protective layer may have a recess. In this case, the surface protective layer is thicker than the above-described surface protective layer 4 and is composed of, for example, multiple gravure printing layers. In this way, the configurations of the translucent substrate and surface protective layer can also be changed as appropriate.

For display devices, the light source may be a display device. The display device may be an LED, LCD, organic EL, etc., and if it has a local dimming function, it can make the image clearer.
