脂製品は、従来モールド成形：二よって製造される場合
、製品の仕上げとしてモールドから脱型さｎた発泡樹脂
製品の表面に塗装を施すことが行なわれている。(Prior technology) Foamed resin products such as soft and semi-rigid polyurethane foams, such as automobile steering wheels, chair cushions, and armrests, are conventionally manufactured by mold molding. Painting has been practiced on the surface of foamed resin products.
近年このような発泡樹脂のモールド製品はきわめて多種

、塗装工程Ｃ二よって後塗装するものでろつ之。In recent years, such foamed resin molded products have become extremely diverse (two-sided products, and products with strong fashion trends such as automobile air spoilers have required multicolored products. Conventionally, foamed resin molded products) To colorize molded products, the foamed resin product is removed from the mold and then post-painted using painting process C2.

トがきわめて高価になる欠点がめった。(Problems to be Solved by the Invention) However, such post-coating methods for foamed resin molded products do not require degreasing, primer coating,
The drawback is that it not only requires an extremely large number of painting processes, such as intermediate coating and top coating processes, and a masking process in the case of multi-color painting, but also requires large-scale painting equipment, making the painting cost extremely high. I was disappointed.
この発明はこのような欠点を解消し、多色塗装であって

。The object of the present invention is to eliminate these drawbacks, to reduce the number of painting steps even in multi-color painting, to make it easy, to eliminate the need for special painting equipment, and to reduce the cost of painting.

装面を有するモールド製品の製造方法である。(Means for Solving Problems Between 2 and 3) This invention provides a molded product by charging a foamable synthetic resin raw material into a foamed resin mold consisting of a split mold, sealing the mold, and foaming the raw material. In this process, a different color paint is applied in advance to the inner surface of each divided mold, after which a foamed resin molded product is obtained, and the paint is transferred and applied to the surface of the foamed resin product, which has a multicolored painted surface. This is a method for manufacturing molded products.

しなくても光沢のすぐれた着色塗装面が形成される。(Function) A different color paint is applied in advance to the inner surface of each mold of the split mold type, and then a foamable synthetic resin raw material is introduced into the mold, the mold is completely sealed, and the raw material is foamed, so that the foamed material is not molded. The paint layer applied to the inner surface of the mold is transferred to the surface of the foam, and the surface of the foam is formed at the parting line of the mold. If the inner surface of the mold is mirror-finished, a colored painted surface with excellent gloss can be formed without a special gloss finish.
