Abstract
An automobile exterior component, having good balance between impact resistance and fluidity and being excellent in coating heat resistance and rigidity, which is prepared by performing urethane coating or melamine coating on a molded article obtained by molding a resin composition which comprises a polyamide resin (A); a grafted polymer (B) prepared by graft polymerizing an aromatic vinyl monomer and a vinyl cyanide monomer in the presence of a diene rubber; PA1 an unsaturated carboxylic acid-modified copolymer (C) which has a reduced viscosity of 0.2 to 0.5 dl/g and is prepared by polymerizing an unsaturated carboxylic acid monomer, an aromatic vinyl monomer and a vinyl cyanide monomer; PA1 a copolymer (D) prepared by polymerizing an aromatic vinyl monomer and a vinyl cyanide monomer; and PA1 talc, wherein the amount ratio of (A), (B), (C) and (D) is in a specific range.
