Therefore, in order to solve the above-mentioned problems, the curable resin decorative material of the present invention includes a decorative layer which is in contact with the curable resin layer, that is, a layer such as a pattern layer or an easily adhesive layer. By forming the layer as a layer using a carboxyl-modified vinyl chloride-vinyl acetate copolymer as a binder, the adhesion between the curable resin layer and the pattern layer was improved. In addition, the adhesiveness of the other layers such as the other pattern layers (not using the specific binder) laminated on the curable resin layer was improved by the easy-adhesion layer. Further, the transfer sheet for forming the pattern layer of such a curable resin decorative material has a structure in which at least a layer of the transfer layer which is in contact with the transfer target is made of a carboxyl-modified vinyl chloride-vinyl acetate copolymer as a binder.

The carboxyl-modified vinyl chloride-vinyl acetate copolymer is a resin having a carboxyl group introduced into the copolymer during or after polymerization of the vinyl chloride-vinyl acetate copolymer. For example, it is a resin obtained by copolymerizing a vinyl monomer having a carboxyl group such as acrylic acid, methacrylic acid, maleic acid, fumaric acid, and itaconic acid together with a vinyl chloride monomer and a vinyl acetate monomer as a copolymer monomer. Further, those obtained by introducing a carboxyl group by various carboxylation reactions or the like after polymerization of the copolymer may be used. Here, the weight ratio of carboxyl groups is 0.3 to 7 of the whole resin.

Further, even when the pattern layer is provided with an adhesive layer using the specific resin as a binder without using the specific resin as a binder of the pattern layer, the transfer layer has a two-layer structure and the number of steps is small. Although this increases, the adhesive layer acts as an easy-adhesion layer, and the adhesion to the curable resin layer can be improved. In this case, as the binder of the pattern layer, a conventionally known resin such as a vinyl acetate, a vinyl chloride-vinyl acetate copolymer, a thermoplastic resin such as a cellulose resin, or a room temperature or thermosetting resin such as a polyurethane. May be used. Although the adhesive layer is provided on the entire surface, a similar configuration in that the adhesive layer is provided on the entire surface is a configuration in which the above-described colored concealing layer is used in combination as a part of the pattern layer. Therefore, the colored concealing layer may be constituted by the binder of the specific resin, and the other part of the pattern layer thereunder (on the side of the releasable support) may be constituted by a pattern layer using another resin as a binder. Needless to say, both may be constituted by the binder of the specific resin.

When a binder of the above-mentioned specific resin is used for the adhesive layer, the pattern layer does not form a layer from the resin binder, and a metal thin film can be used. Alternatively, a layer using a resin binder and a metal thin film are used in combination. For example,
Using a metal such as aluminum, chromium, gold, silver, or copper, a metal thin film formed by a method such as vacuum evaporation or sputtering may be laminated in a whole or in part in a pattern. In addition,
To form a pattern, a removal layer is formed in a desired pattern with a water-soluble ink on an unnecessary portion of the metal thin film, a metal thin film is formed on the entire surface by vapor deposition or the like, and then washed with water and immediately above the removal layer.

The transfer sheet for a curable resin decorative material of the present invention as described above can be used for decoration of various curable resin decorative materials. The transfer layer (decorative layer) may be transferred to the curable resin layer on the transfer sheet of the present invention even after the curable resin layer is completely cured, but is preferably uncured before full curing or a half-curing process such as a so-called B stage. Performing in the cured state is excellent in the effect of improving adhesion. As a typical example of this,
In this case, a decorative plywood is formed by forming a decorative layer on the surface of a wood plywood by transfer, applying an unsaturated polyester resin paint on the decorative layer, and curing the coating. In addition, the transfer layer is not directly transferred to the curable resin layer, but is transferred to another layer, and the curable resin layer is cured by coating the curable resin layer on another layer to which the transfer layer has been transferred. A curable resin decorative material having a configuration in contact with the curable resin layer can also be used. Note that, in this case, at least the outer layer of the transfer layer after transfer uses a transfer sheet using the specific resin as a binder, but if the transfer layer is only a pattern layer, the outer layer is also the same. There is no problem because it is a layer composed of a binder of

The curable resin decorative material of the present invention comprises at least two layers: a curable resin layer and a decorative layer in contact with the layer. For example, if the curable resin layer itself is one in which the decorative material satisfies the mechanical strength required by the application, the curable resin layer and the decorative layer (pattern layer or the like) in contact with the curable resin layer may be used. It is a cosmetic material. In the case where the mechanical strength required for the decorative material cannot be obtained by the curable resin layer itself, for example, a layer other than the curable resin layer such as a resin layer or a wood layer may be laminated or used as another member. By fixing, a curable resin decorative material having mechanical strength suitable for the intended use can be obtained.
The other layer may be laminated with a transparent resin layer or the like to provide a protective function or other decorative effect. When the adhesion is insufficient when the other layer is laminated on the curable resin layer, the above-mentioned carboxyl-modified vinyl chloride-vinyl acetate copolymer is used, depending on the material of the other layer. If the used easy-adhesion layer is used as a layer in contact with the curable resin layer, the adhesion can be improved. For example, there is a case where a thermoplastic resin sheet is laminated as another layer. The curable resin layer may be a single layer or a multilayer such as two layers.
For example, a configuration in which a pattern layer using the above specific resin as a binder is provided between hardening resin layers of the same quality.
