摘要

The invention provides a thermoplastic resin composition whereby a molded article is obtained having excellent flexibility, coating properties, weather resistance, peel properties, dimensional precision, and the like. The thermoplastic resin composition of the present invention comprises 70 mass% of an acrylic rubber reinforced resin obtained by polymerizing a vinyl monomer (a2) in the presence of an acrylic rubber polymer (a1); 10 mass% of a diene rubber reinforced resin obtained by polymerizing a vinyl monomer (b2) in the presence of a diene rubber polymer (b1); and 20 mass% of a vinyl monomer (d2) comprising an aromatic vinyl compound and a vinyl cyanide compound in which the bonded vinyl cyanide content is 33 mass%; the total content of the acrylic rubber polymers (a1) and (b1) therein is 27 mass%; the coefficient of linear expansion thereof is 10x10-5/ DEG C or less; and the flexural modulus thereof according to ISO 178 is 1000 to 2200 MPa.
