Abstract
A thermoplastic resin composition includes a graft copolymer (A) obtained by graft copolymerization of a monomer mixture (a) that includes at least an aromatic vinyl monomer (a1) and a (meth)acrylate monomer (a2), but does not practically contain a vinyl cyanide monomer (a3), in the presence of a rubbery polymer (r) having a refractive index of not lower than 1.510 and not higher than 1.520; and a vinyl copolymer (B). An acetone insoluble component (C) of the thermoplastic resin composition does not practically contain a vinyl cyanide monomer-derived unit. An acetone soluble component (D) of the thermoplastic resin composition contains the vinyl cyanide monomer-derived unit. The content of the vinyl cyanide monomer-derived unit is not lower than 2% by mass and not higher than 20% by mass relative to 100% by mass of the acetone soluble component (D).
