Patent ID: 7217763

Claim:
Acrylonitrile-butadiene-styrene copolymer transparent resin comprising i) 100 weight parts of acrylonitrile-butadiene-styrene copolymer resin having a weight average molecular weight of 60,000 to 250,000, comprising: a) 15 to 40 weight parts of conjugated diene rubber latex; b) 20 to 65 weight parts of methacrylate alkylester or acrylate alkylester compound grafted on the a) conjugated diene rubber latex; c) 8 to 25 weight parts of aromatic vinyl compound grafted on the a) conjugated diene rubber latex; and d) 5 to 20 weight parts of vinyl cyanide compound grafted on the a) conjugated diene rubber latex; and ii) 1 to 30 weight parts of polyester-amide copolymer wherein the difference between the refractive index of the polyester-amide copolymer and that of the acrylonitrile-butadiene-styrene copolymer resin is 0.01 or less.
