Description of the Related Art Conventionally, a melamine resin decorative board is prepared by applying a desired pattern to various types of ink on a base paper (preferably paper called titanium paper) having good permeability to form a printed pattern layer, and then forming a melamine resin. To produce a melamine resin-impregnated printing paper, laminating the printing paper in a configuration as shown in FIG. Specifically, a conventional melamine resin decorative board has a melamine resin impregnated overlay layer for surface protection (melamine resin impregnated overlay paper), a decorative layer (melamine resin impregnated printing paper), and a shielding layer (melamine resin impregnated titanium paper). And a base layer (phenol resin impregnated core paper).

Alternatively, when cost reduction is taken into consideration, it may be omitted as shown in FIG. Generally, the surface of a melamine resin decorative board 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 having a configuration in which no overlay paper is provided on the decorative layer, the printed pattern layer has a casein-based resin, hydroxypropylcellulose, a polyacrylate copolymer, a polymethacrylate, a urea-based resin, and melamine. Since it is formed with an ink using a water-soluble resin such as a base resin as a constituent material of the vehicle, the solvent resistance is poor. Therefore, when the surface of the decorative board is wiped with absorbent cotton or the like using absorbent cotton, the printed pattern layer may transfer to absorbent cotton.

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 of the printing pattern layer,
Contamination by a solvent or the like may be a problem. The eyes of the present invention
Lamin resin-impregnated printing paper imparts sufficient solvent resistance to a melamine resin decorative plate even in a configuration in which no overlay paper is provided on the decorative layer.

Acrylic resin at ℃. When the acid value of the acrylic resin is less than 200, the solvent resistance of the processed surface cannot be sufficiently obtained. On the other hand, when the acid value exceeds 400, the water resistance of the ink and the topcoat varnish itself deteriorates, and the processability of the melamine decorative board becomes poor.

When the temperature is lower than 0 ° C., the acrylic resin is softened at the time of drying after the melamine resin impregnation, and the shape of the printed pattern layer or the top coat layer may be changed. On the other hand, when the temperature exceeds 140 ° C., for example, in the high-pressure melamine method, the melamine resin decorative plate is processed at 140 to 150 ° C., 70 to 100 kg / cm 2 , 1
Since the processing is performed under the heat and pressure condition of about 5 to 20 minutes, the processing surface during processing is not uniform, and there is a possibility that sufficient solvent resistance may not be obtained.

It is preferable that the acrylic resin having a glass transition temperature of 60 to 140 ° C. is used in the range of 20 to 60% by weight of the total resin.
