Abstract
To provide a resin composition comprising a polypropylene resin composition and an aluminum flake pigment for use as an automotive resin composition, which is excellent in mechanical strength, physical properties and flowability, and enables to produce molded products showing good metallic appearance. A composition comprising a crystalline propylene/ethylene block copolymer, an elastomeric polymer and an inorganic filler is a preferred example of the polypropylene resin composition, and aluminum flakes surface-coated with a polymer containing as constituent units acrylic acid, an acrylic acid ester, epoxylated polybutadiene and divinylbenzene are preferred examples of the aluminum flake pigment.
