Abstract

A thermoplastic resin composition comprises a thermoplastic resin (A) and graft copolymer particles (B) having a hollow rubber portion and graft chain, in which a volumetric proportion of hollow part in the hollow rubber portion of the graft copolymer particles is 1 to 70% by volume. The thermoplastic resin composition contains the thermoplastic resin and the graft copolymer particles in a weight ratio (A)/(B) of 2/98 to 100/1. The hollow part in the graft copolymer particle functions to further improve impact resistance.
