Abstract:
Provided is an aromatic polycarbonate resin composition that is excellent in terms of hue and thermal yellowing-inhibiting effect and is suitable for light guide members incorporated in automobile lighting devices. The aromatic polycarbonate resin composition comprises: 100 parts by mass of an aromatic polycarbonate resin (A); 0.001 to 0.1 parts by mass of a phosphite stabilizer (B-I) as a phosphorus-based stabilizer (B) having a spiro ring skeleton; 0.01 to 0.5 parts by mass of a phosphite stabilizer (B-II) as a phosphorus-based stabilizer (B) represented by general formula (II) below; 0.05 to 2 parts by mass of a polybutylene glycol compound (C); and 0.0005 to 0.2 parts by mass of an epoxy compound (D). In the formula (II), R21 to R25 each independently represent a hydrogen atom, an aryl group having 6 to 20 carbon atoms, or an alkyl group having 1 to 20 carbon atoms.
