Abstract
A thermoplastic resin composition containing PA1 (A) 100 parts by weight of: PA2 (1) a polycarbonate resin, and PA2 (2) a copolymer containing: PA3 (a) a rubber polymer PA3 (b) an aromatic vinyl monomer component, and PA3 (c) a vinyl cyanide monomer component, PA2 or a polystyrene resin; PA1 (B) 1-30 parts by weight of an addition polymer containing units derived from glycidyl (meth)acrylate; and PA1 (C) 0.001-1 part by weight of a compound such as an organic acid, phosphoric acid, phosphorous acid, hypophosphoric acid and/or a compound other than an organic acid that has one or more functional groups selected from among carboxyl, amino, hydroxyl, acid anhydride and thiol groups.
