Abstract

An object is to provide a coloring technique that makes it possible to impart luster while providing a vivid color, and further to provide a coloring technique that makes it possible to retain more unevenness when a substrate has unevenness. This object is achieved by a laminated sheet comprising a fiber substrate and a metalloid element-containing layer disposed on or above the surface of the fiber substrate.

First claim

The invention claimed is:

1. A laminated sheet comprising a fiber substrate, a metalloid element-containing layer disposed directly on a surface of the fiber substrate, and a metal or metalloid oxide layer on a surface of the metalloid element-containing layer on a side opposite to the fiber substrate side,
the fiber substrate being in the form of a sheet,
the fiber substrate having a thickness of 0.01 to 10 mm,
the fiber substrate being at least one member selected from the group consisting of a woven fabric, a knitted fabric, and a nonwoven fabric, and
the metal or metalloid oxide layer comprising one or more compounds represented by AO X ,
wherein X is a number satisfying the following formula: n/2.5≤X≤n/2,
wherein n is the valence of a metal or metalloid, and

wherein A is a metalloid element or metallic element selected from the group consisting of silicon, germanium, antimony, tellurium, bismuth, selenium, titanium, aluminum, niobium, nickel, and cobalt.

2. The laminated sheet according to claim 1 , wherein the fiber substrate is a carbonaceous substrate.

3. The laminated sheet according to claim 1 , wherein the metalloid element constituting the metalloid element-containing layer is at least one member selected from the group consisting of silicon, germanium, antimony, tellurium, boron, phosphorus, bismuth, and selenium.

4. The laminated sheet according to claim 1 , wherein the ratio of the thickness of the oxide layer to the thickness of the metalloid element-containing layer is 0.05 or more and 1 or less.

5. A laminated sheet comprising:
a fiber substrate,
a metal layer, and
a metalloid element-containing layer,
wherein the metal layer is between the metalloid element-containing layer and the fiber substrate,
wherein the fiber substrate is in the form of a sheet,
wherein the fiber substrate has a thickness of 0.01 to 10 mm,
wherein the fiber substrate is at least one member selected from the group consisting of a woven fabric, a knitted fabric, and a nonwoven fabric,
wherein the ratio of the thickness of the metalloid element-containing layer to the thickness of the metal layer is 0.01 or more and 10 or less,
wherein the laminated sheet further comprises a metal or metalloid oxide layer on a surface of the metalloid element-containing layer on a side opposite to the fiber substrate side, and
wherein the metal or metalloid oxide layer comprises one or more compounds represented by AO X ,
wherein X is a number satisfying the following formula: n/2.5≤X≤n/2,
wherein n is the valence of a metal or metalloid, and

wherein A is a metalloid element or metallic element selected from the group consisting of silicon, germanium, antimony, tellurium, bismuth, selenium, titanium, aluminum, niobium, nickel, and cobalt.

6. The laminated sheet according to claim 5 , wherein the difference in refractive index between the metalloid element-containing layer and the metal layer is 2 or more; and the metalloid element-containing layer has a thickness of 1 nm or more and 40 nm or less.

7. The laminated sheet according to claim 6 , wherein the difference in extinction coefficient between the metalloid element-containing layer and the metal layer is a negative value, and the absolute value thereof is 1.5 or more.

8. The laminated sheet according to claim 1 , wherein the fiber substrate is a carbon fiber substrate.

9. A composite material comprising a resin and the laminated sheet according to claim 1 .

10. The composite material according to claim 9 , which is a fiber-reinforced plastic.

11. The laminated sheet according to claim 1 , wherein the thickness of the fiber substrate is 0.05 to 10 mm.

12. The laminated sheet according to claim 1 , wherein the oxide layer comprises silicon.

13. The laminated sheet according to claim 1 , wherein the oxide layer comprises SiO 2 .

14. The laminated sheet according to claim 8 , wherein the carbon fiber substrate comprises carbon fibers having an average diameter of 1,000 to 30,000 nm.

15. The laminated sheet according to claim 1 , wherein the laminated sheet has a Chroma C* value of 19.37 or more as measured according to JIS Z8781-4 (2013).

16. The laminated sheet according to claim 1 , wherein the thickness of the metalloid element-containing layer is 1 nm or more and 100 nm or less.

17. A laminated sheet comprising a fiber substrate, a metalloid element-containing layer disposed directly on a surface of the fiber substrate, and a metal or metalloid oxide layer on a surface of the metalloid element-containing layer on a side opposite to the fiber substrate side,
the fiber substrate being in the form of a sheet,
the fiber substrate having a thickness of 0.01 mm to 10 mm,
the fiber substrate being at least one member selected from the group consisting of a woven fabric and a knitted fabric, and
the metal or metalloid oxide layer comprising one or more compounds represented by AO X ,
