Embodiment 1

[0072] First, as the base paper 6, titanium paper for decorative paper having good water absorption was prepared. Subsequently, the wood grain texture was printed on the surface 6a of the base paper 6 by using an aqueous ink containing casein as the main component to form a pattern texture layer 7 with a layer thickness of 10 μm. As a printing method, a gravure printing method was used. Next, using a water-based ink containing a foaming agent and mainly composed of epoxy resin, the surface 7a of the pattern texture layer 7 is printed with a conduit texture that is designed to synchronize with the wood grain texture of the pattern texture layer 7. The foamed resin layer 8 is arranged in the shape of a duct texture. As a printing method, a direct gravure printing method was used. As the foamed resin layer 8 , one having an average particle diameter of 100 μm before foaming (10 times the layer thickness of the pattern texture layer 7 ), an average particle diameter after foamin...

Embodiment 2

[0075] In Example 2, a casein-based resin was used as the thermosetting resin layer 9 . Except for this, a resin-impregnated decorative board 1 was produced with the same materials and procedures as in Example 1.

Embodiment 3

[0077] In Example 3, an acrylic resin was used as the thermosetting resin layer 9 . Except for this, a resin-impregnated decorative board 1 was produced with the same materials and procedures as in Example 1.

Abstract

The resin-impregnated decorative paper (2) is obtained by impregnating the decorative paper (4) with the impregnating resin (5). The decorative paper (4) is provided with: a base paper (6); a pattern texture layer (7) provided on the surface (6a) side of the base paper (6); a foamed resin layer (8) formed from a foaming agent disposed on the surface (7a) of the pattern texture layer (7) or in the pattern texture layer (7); and a thermosetting resin layer (9) provided on the surface (8a) of the foamed resin layer (8). The thermosetting resin layer (9) contains at least one of an epoxy resin, a casein resin, an acrylic resin, and a urethane resin.

Description

technical field [0001] The present invention relates to resin-impregnated decorative paper and resin-impregnated decorative board. Background technique [0002] Conventionally, a method for producing a resin-impregnated decorative sheet has been proposed, in which a resin-impregnated decorative sheet is obtained by abutting a metal sheet on a laminate of a resin-impregnated decorative paper and a base material impregnated with a thermosetting resin, and heat-pressing molding to obtain a resin-impregnated decorative sheet A resin-impregnated decorative board in which paper and a base material are integrated (for example, refer to Patent Document 1). In the manufacturing method of the resin-impregnated decorative plate described in Patent Document 1, an embossed shape is provided on a metal plate to impart a textured texture to the surface of the resin-impregnated decorative plate, thereby imparting a touch to the hand. In addition, it is also possible to impart a matt expres...
