Abstract

There is provided a resin-impregnated decorative paper (2) formed by impregnating a decorative paper (4) with an impregnating resin (5). The decorative paper (4) includes: a base paper (6); a picture pattern layer (7) provided on a surface (6a) side of the base paper (6); a filling layer (8) provided on a surface (7a) of the picture pattern layer (7); and a foamed resin layer (9) provided on a surface (8a) of the filling layer (8). The filling layer (8) contains at least one of an epoxy-based resin, an acrylic-based resin, a urethane-based resin, and a casein-based resin.

First claim

The invention claimed is:

1. A resin-impregnated decorative paper formed by impregnating a decorative paper with an impregnating resin, the decorative paper comprising:
a base paper;
a picture pattern layer provided on a surface side of the base paper;
a filling layer provided on a surface of the picture pattern layer; and
a foamed resin layer provided on a surface of the filling layer, the foamed resin layer formed by a foaming agent,
wherein the filling layer contains at least one of an epoxy-based resin, an acrylic-based resin, a urethane-based resin, and a casein-based resin, and
wherein the filling layer has a thickness of 0.5 μm or more and 7 μm or less.

2. The resin-impregnated decorative paper according to claim 1 , wherein the filling layer is provided in a range of 100% or more of a surface area of the foamed resin layer.

3. The resin-impregnated decorative paper according to claim 2 , wherein the filling layer is provided in a range of 150% or less of the surface area of the foamed resin layer.

4. The resin-impregnated decorative paper according to claim 1 , wherein the foamed resin layer contains a colored ink.

5. The resin-impregnated decorative paper according to claim 1 , wherein a picture formed by the picture pattern layer and an arrangement position of the foamed resin layer are aligned with each other.

6. A resin-impregnated decorative plate comprising:
the resin-impregnated decorative paper according to claim 1 ; and
a base member integrated with the resin-impregnated decorative paper.

7. The resin-impregnated decorative paper according to claim 2 , wherein the foamed resin layer contains a colored ink.

8. The resin-impregnated decorative paper according to claim 3 , wherein the foamed resin layer contains a colored ink.

9. The resin-impregnated decorative paper according to claim 2 , wherein a picture formed by the picture pattern layer and an arrangement position of the foamed resin layer are aligned with each other.

10. The resin-impregnated decorative paper according to claim 3 , wherein a picture formed by the picture pattern layer and an arrangement position of the foamed resin layer are aligned with each other.

11. The resin-impregnated decorative paper according to claim 4 , wherein a picture formed by the picture pattern layer and an arrangement position of the foamed resin layer are aligned with each other.

12. A resin-impregnated decorative plate comprising:
the resin-impregnated decorative paper according to claim 2 ; and
a base member integrated with the resin-impregnated decorative paper.
