Disclosed is a resin composition comprising (A) from 1-98 wt. parts of a graft copolymer obtained by graft-polymerizing (a) 5-80 wt. % of a rubbery polymer and (b) 95-20 wt. % of a monomer mixture consisting of 40-90 wt. % of an aromatic vinyl compound, 60-10 wt. % of a vinyl cyanide compound and 0-50 wt. % of another ethylenically unsaturated compound copolymerizable therewith, (B) 1-40 wt. % parts of a modified copolymer selected from (B.sub.1) a modified vinyl copolymer obtained by polymerizing (a) 40-90 wt. % of an aromatic vinyl compound, (b) 60-10 wt. % of a vinyl cyanide compound, (c) 0.01-10 wt. % of a monomer having an epoxy, carboxyl or amino group, and (d) 0-40 wt. % of another ethylenically unsaturated compound, and (B.sub.2) a modified olefinic copolymer obtaind by copolymerizing (e) 50-95 wt. % of ethylene or propylene, (f) 0.1-20 wt. % of a monomer having an epoxy, carboxyl or amino group, and (g) 0-40 wt. % of another ethylenically unsaturated compound, (C) 1-60 wt. parts of an imidized acrylic resin, and (D) from 0-90 wt. parts of a vinyl copolymer obtained by polymerizing (a) 40-90 wt. % of an aromatic vinyl compound, (b) 60-10 wt. % of a vinyl cyanide compound and (c) 0-40 wt. % of another ethylenically unsaturated compound, wherein the content of the rubbery polymer (a) in the graft copolymer (A) is 5 to 40 wt. % based on the resin composition. This resin composition gives a shaped article having a delustered and pleasing appearance and a good impact resistance.
