Abstract
The purpose of the present invention is to provide a thermoplastic resin composition for a reflector plate with which it is possible to obtain a molded article having excellent moldability, high mechanical strength, excellent heat resistance and a high reflectance that is stable over time, and it is possible to obtain a reflector plate with which there is little reduction in reflectance due to heating. The thermoplastic resin composition for a reflector of the invention comprises 30 to 80 weight % of a thermoplastic resin (A) having structural units containing carbonyl groups and a melting point or glass transition temperature of 250° C. or higher, 10 to 50 weight % of an inorganic filler (B) containing an inorganic filler (B-1) that comprises a carbonyl structure and has an aspect ratio of 10 to 100, and 5 to 50 weight % of a white pigment (C).
