Description of the Related Art Conventionally, a melamine resin decorative board is produced by forming a printed pattern layer by applying a desired pattern with various inks to a decorative board base paper (preferably a paper called titanium paper) having good permeability. Is produced by laminating the printing paper with a constitution as shown in FIG. 3 and then heat-pressing. Specifically, the conventional melamine resin decorative board has a melamine resin-impregnated overlay layer (melamine resin-impregnated overlay paper) for surface protection, a decorative layer (melamine resin-impregnated printed paper), and a shielding layer (melamine resin-impregnated titanium paper). And a base material layer (phenol resin-impregnated core paper).

くと、印刷模様層が脱脂綿に移行することがあった。In the above-mentioned constitution, the melamine resin-impregnated overlay paper laminated on the decorative layer is used when the pattern of the decorative layer is desired to be clearly expressed or when high scratch resistance is not required,
Alternatively, if cost reduction is considered, it may be omitted as shown in FIG. In general, the surface of a melamine resin decorative board heat-pressed and formed by laminating a melamine resin-impregnated overlay paper on a decorative layer has solvent resistance. However, on the surface of the melamine resin decorative plate with no overlay paper on the decorative layer, the printed pattern layer is casein-based resin, hydroxypropyl cellulose, polyacrylic acid ester copolymer, polymethacrylic acid ester, urea-based resin, melamine. Since the ink is formed of a water-soluble resin such as a base resin as a constituent material of the vehicle, it has poor solvent resistance. Therefore, when the surface of the decorative plate is wiped with absorbent cotton, such as with a Rucker thinner, the printed pattern layer may be transferred to absorbent cotton.

In the decorative paper for use, the printed pattern layer has an acid value of 200 to 400 and a glass transition temperature of 60 to 1
Provided is a decorative paper for a melamine resin decorative board, which is formed by using an ink having an acrylic resin of 40 ° C. as a constituent material of a vehicle. The present invention also relates to a decorative paper for a melamine resin decorative board, which comprises forming a printed pattern layer on the decorative board base paper and then impregnating the entire decorative board base paper with a melamine resin on the decorative board base paper. On top of the,
Acid value 200-400, and glass transition temperature 60-140
Provided is a decorative paper for a melamine resin decorative board, which is characterized by forming a topcoat layer using a topcoat varnish containing an acrylic resin at 0 ° C.

化粧板に付与する。The role of the overlay paper, which is provided on the decorative layer when the melamine resin decorative board is processed, is to protect the surface of the melamine resin-impregnated printing paper which is the decorative layer. When the impregnated printing paper comes to the top of the laminated structure, the conventional melamine resin impregnation amount alone cannot sufficiently protect the ink in the printed pattern layer.
Contamination due to solvents etc. may be a problem. The decorative paper for a melamine resin decorative board of the present invention imparts sufficient solvent resistance to the melamine resin decorative board even if the overlay paper is not provided on the decorative layer.
