THERMOPLASTIC RESIN COMPOSITION FOR LIGHT REFLECTOR, FORMED ARTICLE FOR LIGHT REFLECTOR, LIGHT REFLECTOR, AND METHOD FOR PRODUCING FORMED ARTICLE FOR LIGHT REFLECTOR

摘要

Disclosed are a thermoplastic resin composition for light reflectors which contains 2-45 parts by mass of an inorganic filler (B1) which is treated with a fatty acid based surface-finishing agent and has an average particle diameter of not more than 3 mum, per 100 parts by mass of a thermoplastic resin (A); a thermoplastic resin composition for light reflectors which contains 2-45 parts by mass of an inorganic filler (B2) with an average particle diameter of not more than 3 mum whose refractive index alpha is 1.61 <= alpha <= 2.5, per 100 parts by mass of a thermoplastic resin (A); and a thermoplastic resin composition for light reflectors which contains 0.01-3 parts by mass of a fatty acid glycerol triester and/or a fatty acid glycerol diester (C1) and 0.01-3 parts by mass of a fatty acid glycerol monoester (C2) per 100 parts by mass of a thermoplastic resin (A). Also disclosed are a formed article for light reflectors which is made of one of such thermoplastic resin compositions and a light reflector obtained by directly forming a light-reflecting metal layer on at least a part of the surface of such a formed article for light reflectors.
