摘要

PURPOSE: A polyester resin composition is provided to have excellent initial reflectivity, thermal resistance, impact strength, and yellowing resistance, thereby minimizing the yellowing phenomena after remaining in high temperatures and high temperature and/or high humidity conditions. CONSTITUTION: A polyester resin composition comprises 100.0 parts by weight of a high thermal resistant polyester-based resin, which consists of a structure with a backbone originated from an aromatic dicarboxylic acid and an aliphatic diol and a melting point of 200C or more; 0.1-80 parts by weight of a white pigment; 0.01-2 parts by weight of a photostabilizer; and 0.01-2 parts by weight of a sulfur compound. A diol component for composing the high thermal resistant polyester-based resin includes 15-100 mol% of 1,4-cyclohexanedimethanol and 0-85 mol% of an ethylene glycol.
