Light-diffusing polycarbonate resin composition and light-diffusing plate

摘要

A polycarbonate-base light-diffusing resin composition contains: (A) 100 parts by mass of an aromatic polycarbonate resin; (B) 0.01 to 10 parts by mass of a light diffusing agent; (C) 0.05 to 5 parts by mass of a light resistant agent, the light resistant agent being one or more light resistant agent selected from a malonate-base compound, an oxalylanilide-base compound, a benzotriazole-base compound and an acrylic resin having a side chain of a benzotriazole-base skeleton; and 0.01 to 1 parts by mass of an ester compound of fatty acid and multivalent alcohol. By molding the composition by injection molding or the like, a light diffusing plate is obtained.
