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

摘要

Thermoplastic resin compositions for a light reflector contain 2 to 45 parts by mass per 100 parts by mass of a thermoplastic resin (A) of an inorganic filler (B1) treated with a fatty acid type surface treating agent and having an average particle diameter of not more than 3 mum, or 2 to 45 parts by mass of an inorganic filler (B2) having a refractive index alpha of 1.61@alpha@2.5 and having an average particle diameter of not more than 3 mum, 0.01 to 3 parts by mass of glycerol triester of a fatty acid and/or a glycerol diester of a fatty acid (C1), and 0.01 to 3 parts by mass of a glycerol monoester of a fatty acid (C2). A molded article for a light reflector and a light reflector in which a light reflecting metal layer is directly formed on at least a part of the surface of the molded article is produced from one of such thermoplastic resin compositions.
