In the resin molded product with a picture of the present invention, the paper base material 4 is impregnated with a melamine resin varnish having a molar ratio of formalin and melamine at the time of resin synthesis of 1.4 to 1.7.
Is formed, and the patterning resin-impregnated paper 1 is laminated on the melamine resin molded product 3 on the side surface of the printing ink layer 2 and the above problem is solved by this configuration. [Function] Since the printing ink layer 2 side is located on the melamine resin molded product 3 side, the pattern portion (ink portion) is not exposed on the surface of the painted resin molded product A, and the picture base of the patterned resin-impregnated paper 1 is not exposed. Since the resin of the patterning resin-impregnated paper 1 and the melamine resin molded product 3 are the same kind of resin by being protected by the material 4, the patterning resin-impregnated paper 1 and the melamine resin molded product 3 are strong. By being laminated on, the pattern portion (ink portion) does not swell even after repeated boiling and drying or steam disinfection treatment. Hereinafter, the present invention will be described with reference to the accompanying drawings. As the paper base material 4 of the patterned resin-impregnated paper 1, usually used base materials such as machine finish paper, super finish paper, art paper, bond paper, carton paper, glassine paper and cellophane paper are used. The paper base material 4 is impregnated with a melamine resin varnish having a formalin / melamine molar ratio of 1.4 to 1.7 during resin synthesis, dried, and printed with a printing ink to form a printing ink layer 2. Thus, the patterned resin-impregnated paper 1 is manufactured.
In this case, the melamine resin of the melamine resin varnish has a high water content and can be suitably used in combination with an aqueous printing ink. The composition of the printing ink is determined in relation to the paper base material 4. For example, in the case of bond paper, the vehicle is linseed oil varnish, resin varnish, or alkyd varnish that has a high viscosity and forms a strong film. The patterned resin-impregnated paper 1 is laminated on the melamine resin molded product 3 on the side surface of the printing ink layer 2 by heating and pressing to form a resin molded product A with a picture. For example, a patterned resin-impregnated paper 1 is formed by using a melamine resin varnish having a formalin / melamine molar ratio of 1.5 at the time of resin synthesis, and the patterned resin-impregnated paper 1 is laminated on a melamine resin molded product 3 to obtain a resin molded product with a picture. When manufactured and subjected to a continuous boiling resistance test, this product showed a durability of 100 hours or more. On the other hand, in the case of the conventional one, remarkable swelling appeared in the pattern part (ink part) in 10 to 20 hours.

In the present invention, a melamine resin varnish having a formalin / melamine molar ratio of 1.4 to 1.7 during resin synthesis is impregnated into a paper base material to form a patterned resin-impregnated paper. Since the resin-impregnated paper is laminated on the melamine resin molded product on the side of the printing ink layer, the melamine resin of the melamine resin varnish has a high water content, and can be suitably used in combination with an aqueous printing ink. Yes,
Also, since the printing ink layer side is located on the melamine resin molded product side, the pattern part (ink part) is on the surface of the painted resin molded product.
Will not be exposed and will be protected by the picture base material of the patterned resin-impregnated paper, and since the resin of the patterned resin-impregnated paper and the melamine resin molded article are the same type of resin,
The patterned resin-impregnated paper and the melamine resin molded product are firmly laminated, and the pattern portion (ink portion) does not swell even after repeated boiling and drying or steam disinfection treatment.
