Abstract

To provide a resin composition which is excellent in impact resistance and tensile elongation, in which deterioration of appearance (fish eyes, glossiness) caused by aggregation of rubbery polymers is suppressed, and which has good color development properties. [Solution] A graft copolymer (A) is obtained by graft copolymerizing a monomer mixture (a) containing at least an aromatic vinyl monomer (a1) and a vinyl cyanide monomer (a2) in the presence of a rubber polymer (r), and a vinyl copolymer (B) is obtained by copolymerizing a monomer mixture (b) containing at least an aromatic vinyl monomer (b1) and a vinyl cyanide monomer (b2). The graft copolymer (A) contains specific amounts of either or both of a specific phosphate ester compound (E1) and a polyoxyethylene alkylamine (E2).
