Abstract
The purpose of the present invention is to provide a thermoplastic resin composition for a reflective material which has excellent mechanical strength, excellent heat resistance, excellent high reflectance, and excellent moldability, and which makes it possible to obtain a reflective plate with little decline in reflectance caused by heating. A first embodiment of this thermoplastic resin composition for a reflective material includes: a polyester resin (A) that has a melting point or glass transition temperature of 250° C. or higher and includes an alicyclic hydrocarbon structure; a thermoplastic resin (B) that has a polyolefin backbone and a functional group; a white pigment (C); and an inorganic filler (D); the thermoplastic resin (B) either including 0.1 to 1.8 wt % of a functional group unit (B1) that further includes a heteroatom, or further including an aromatic hydrocarbon structure (B2), and the limiting viscosity [η] being 0.04 to 1.0 dl/g.
