PURPOSE:To obtain a resin molded product improved in film adherability by molding a polypropylene composition containing two kinds of copolymer rubbers or a polypropylene composition further containing an inorg filler in addition to said rubbers and applying top coat to the molded body to bake the same. CONSTITUTION:A polypropylene composition containing ethylene/propylene copolymer rubber and ethylene/propylene/diene terpolymer rubber or a polypropylene composition further containing an inorg. filler (pref., fine powdery calcium carbonate, barium sulfate, calcium silicate or talc) in addition to said rubbers is molded. This molded product is brought into contact with a liquid or vapor of a halogen-containing org. solvent or an aromatic org. solvent to be placed in an atmosphere held to about 40-100 deg.C. Thereafter, top coat is applied to the molded product to perform baking at 110-150 deg.C. By this method, a polypropylene resin molded article improved in film adherability can be obtained even when plasma treatment or primer coating is not performed. |
