ABSTRACT:
A resin composition is provided which comprises a mixture of A) 100 parts by weight of an ABS graft copolymer comprising as component monomers an acrylonitrile compound and a vinyl aromatic compound in a weight ratio of 10:90 to 50:50, and B) 5 to 30 parts by weight of an ethylene oxide copolymer comprising ethylene oxide as a first monomer and a second monomer and containing at least 50 wt. % of ethylene oxide, the ethylene oxide copolymer having a refractive index (n.sub.D.sup.20) of at least 1.50, wherein said second monomer has a refractive index of at least 1.54 and is 2-phenylphenyl glycidyl ether or 1-naphthyl glycidyl ether, and wherein the molecular weight of the ethylene oxide copolymer is 1 to 5 in terms of a reduced viscosity as measured at 80.degree. C. using 0.1 g/dl monochlorobenzene solution thereof.
