(57) [Summary] [Objective] The present invention adopts a streamlined painting process while meeting the demand for weight reduction and cost reduction, and the parts after painting have a feeling (particularly soft touch property) and a coating film adhesion property. , Appearance (texture It is an object of the present invention to provide an injection-molded part for automobiles, which has excellent gloss and little deformation. According to the present invention, as shown in FIG. 1, an insert portion (A layer) made of a polypropylene resin and a skin portion (B layer) made of a thermoplastic elastomer are integrally fused by injection molding. In the injection-molded part in which the surface of the skin of the injection-molded article is covered with a coating film (C layer), the A layer is a polypropylene resin, the B layer is ethylene, The modified styrenic elastomer containing the unsaturated carboxylic acid copolymer, the C layer, the resin component of the main component of the two-component urethane-based paint is the addition polymer of the isocyanate-based resin and the polycarbonate polyol as the main component, and cured. It is a coating composition whose main component is an addition polymer of an aliphatic diisocyanate. Especially. |
