ABSTRACT:
Disclosed is a method of molding an automobile outer trim part, including the steps of: (1) providing a film or sheet comprising a colored layer composed of a propylene polymer composition and, laminated thereto, a clear layer composed of a propylene homopolymer, (a) heating the laminated film or sheet, (3) feeding the heated laminated film or sheet into a metal mold including a pair of dies, (4) closing the metal mold so that the laminated film or sheet is shaped into desired configuration, (5) loosing the closed metal mold, and (6) injecting a thermoplastic polymer onto the side of the colored layer of the metal mold so that the shaped laminated film or sheet is united with a substrate layer of the thermoplastic polymer. The above propylene polymer composition comprises in a specified proportion a polypropylene block copolymer and/or polypropylene random copolymer exhibiting a specified intrinsic viscosity, a polyethylene exhibiting a specified intrinsic viscosity, an elastomer composed of a copolymer of ethylene and an .alpha.-olefin exhibiting a specified intrinsic viscosity and a colorant. The above method enables providing an automobile outer trim part having the same colored appearance and texture as those of painted part, irrespective of the avoidance of a printing step.
