PCT No. PCT/JP97/01663 Sec. 371 Date Nov. 17, 1998 Sec. 102(e) Date Nov. 17, 1998 PCT Filed May 16, 1997 PCT Pub. No. WO97/44892 PCT Pub. Date Nov. 27, 1997Rubber-modified styrenic resin compositions of this invention comprise 90 to 30% by weight of rubber-modified styrenic resins (A) containing rubbery polymers dispersed with an average particle diameter of 0.3 to 2.0 mu m in the phase of styrenic polymers (C) and 10 to 70% by weight of styrene-(meth)acrylate ester copolymer resins (B) and, in said compositions, the content of (meth)acrylate ester units is 5 to 50% by weight and the toluene-insolubles (% by weight: X) and the rubber component (% by weight: Y) are present at a ratio (X/Y) in the range from 1.2 to 3.5. The compositions excel in appearance, scratch resistance, impact resistance and rigidity and are easy to fabricate.
