The invention relates to a resin composition having an excellent balance in the physical properties between chemical resistance and impact strength which is obtained by mixing at least one graft copolymer selected from the group consisting of a graft copolymer in which a copolymer rubber comprising an alkyl acrylate and a conjugated diene is used, a graft copolymer in which a rubber prepared by seed rubber polymerization of an alkyl acrylate with a conjugated diene rubber is used, and a graft copolymer in which a rubber prepared by seed rubber polymerization of an alkyl acrylate with a polyorganosiloxane rubber is used, with a graft copolymer in which a conjugated diene rubber is used, and optionally with a rigid thermoplastic resin.
