Abstract
A method for surface treating a resin composition molded article and a method for coating a resin composition molded article are disclosed, which comprise irradiating a molded article with ultraviolet light having an irradiation wavelength in the region of 300 nm or less and, if desired, coating the thus UV-irradiated surface with a coating, the molded article being obtained from a resin composition comprising (I) 100 parts by weight of a resin composition comprising (A) from 5 to 99.5% by weight of a polypropylene resin selected from the group consisting of polypropylene, modified polypropylene, and a modified polypropylene/polypropylene composition and (B) from 0.5 to 95% by weight of at least one thermoplastic resin selected from the group consisting of a polyamide resin, a polyphenylene ether resin, a mixture of a polyphenylene ether resin and a styrene resin, a graft copolymer of a polyphenylene ether resin and styrene, and a saturated polyester resin; and (II) up to 30 parts by weight of at least one compatibilizer for improving compatibility between the polypropylene resin (A) and the thermoplastic resin (B), the compatabilizer being selected from the group consisting of an unsaturated carboxylic acid compound having at least one carboxyl group in the molecule thereof or a derivative thereof, a diamine compound having at least two nitrogen atoms in the molecule thereof or a derivative thereof, and an epoxy-containing copolymer.
