Abstract

There is provided a decorative sheet which has satisfactory heat-shielding properties and can exhibit a design which is excellent in the degree of darkness. The decorative sheet includes an infrared-reflective substrate, and a decorative layer disposed on the substrate and including a solid printing layer and a picture layer, wherein the solid printing layer contains an infrared-transparent or infrared-reflective pigment and a binder resin, the infrared-transparent or infrared-reflective pigment containing (A) at least three compounds selected from the pigment group consisting of a quinacridone, an isoindolinone, a nickel azo complex and a phthalocyanine, or (B) at least one compound selected from the pigment group consisting of a composite oxide containing manganese and at least one metal element other than manganese, an azomethine-azo compound and a perylene compound, and wherein the picture layer at least partly contains carbon black and a binder resin.

First claim

1 . A decorative sheet comprising an infrared-reflective substrate, and a decorative layer disposed on the substrate and including a solid printing layer and a picture layer,
wherein the solid printing layer contains an infrared-transparent or infrared-reflective pigment and a binder resin, the infrared-transparent or infrared-reflective pigment containing (A) at least three compounds selected from the pigment group consisting of a quinacridone, an isoindolinone, a nickel azo complex and a phthalocyanine, or (B) at least one compound selected from the pigment group consisting of a composite oxide containing manganese and at least one metal element other than manganese, an azomethine-azo compound and a perylene compound, and wherein the picture layer contains carbon black and a binder resin.

2 . The decorative sheet according to claim 1 , wherein the solid printing layer contains the infrared-transparent or infrared-reflective pigment in an amount of 5 to 80% by mass based on the solid content of the solid printing layer.

3 . The decorative sheet according to claim 1 , wherein the thickness of the solid printing layer is 0.5 to 15 μm.

4 . The decorative sheet according to claim 1 , wherein the picture layer contains the carbon black in an amount of 0.1 to 5.0% by mass based on the solid content of the picture layer.

5 . The decorative sheet according to claim 1 , wherein the thickness of the picture layer is 0.5 to 20 μm.

6 . The decorative sheet according to claim 1 , wherein the infrared-reflective substrate contains a composite oxide containing manganese and at least one metal element other than manganese.

7 . The decorative sheet according to claim 6 , wherein the infrared-reflective substrate has an L* value of the CIE (International Commission on Illumination) L*a*b* color system, measured according to JIS Z8781-4:2013, of not more than 60.

8 . The decorative sheet according to claim 6 , wherein the infrared-transparent or infrared-reflective pigment contains (A) at least three compounds selected from the pigment group consisting of a quinacridone, an isoindolinone, a nickel azo complex and a phthalocyanine.

9 . The decorative sheet according to claim 1 , wherein the infrared-reflective substrate contains titanium oxide.

10 . The decorative sheet according to claim 9 , wherein the infrared-reflective substrate has an L* value of the CIE (International Commission on Illumination) L*a*b* color system, measured according to JIS Z8781-4:2013, of not less than 80.

11 . The decorative sheet according to claim 9 , wherein the infrared-transparent or infrared-reflective pigment contains (B) at least one compound selected from the pigment group consisting of a composite oxide containing manganese and at least one metal element other than manganese, an azomethine-azo compound and a perylene compound.

12 . The decorative sheet according to claim 1 , wherein the proportion of the area of the picture layer to the entire area of the decorative sheet is not more than 50%.

13 . The decorative sheet according to claim 1 , further comprising at least one of a transparent resin layer and a protective layer, disposed on the decorative layer.

14 . The decorative sheet according to claim 1 , wherein the decorative sheet has an L* value of the CIE (International Commission on Illumination) L*a*b* color system, measured according to JIS Z8781-4:2013, of not more than 45 in an area which lies in the decorative layer-side surface of the decorative sheet and in which the solid printing layer and the picture layer exist.

15 . A decorative material comprising an adherend and the decorative sheet according to claim 1 .
