Abstract
Abstract A thermoplastic resin composition excellent in coating property which comprises (A) at least one of polyamide resins and polyacetal resins, (B) at least one of aromatic monovinyl compound/vinyl cyanide copolymers comprising units of aromatic monovinyl compounds and units of vinyl cyanides in a weight ratio of 60:40 to 80:20 and having an intrinsic viscosity of 0.3 to 1.1 and (C) at least one of conjugated diene rubber/vinyl cyanide graft copolymers comprising units of conjugated diene rubbers in an amount of 5 to 45% by weight based on the weight of the graft copolymers in a weight proportion of the components (A), (B) and (C) being 0.1-10: 5-90: 5-94.9.
