Abstract
A thermoplastic resin composition including a graft copolymer (B) produced by graft polymerization of a vinyl monomer mixture (m1) including an alkyl (meth)acrylate ester, a vinyl cyanide compound, and an aromatic vinyl compound onto a copolymer (A) produced by copolymerizing an alkyl (meth)acrylate ester (a) and a (meth)acrylate ester (b) including an aromatic hydrocarbon group at a specific ratio and a copolymer (C) that is a product of a polymerization reaction of a vinyl monomer mixture (m2) including an alkyl (meth)acrylate ester. The graft copolymer (B) includes at least a graft copolymer (B) having a specific volume-average particle size. The copolymer (A) has a specific volume-average particle size and a specific particle size distribution.
