POLYESTER RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a polyester resin composition having a good brightness feeling, a high reflectance and good metal adhesion even when vapor deposition of a photoreflective metal layer is directly carried out on a resin molded product without carrying out undercoating and usable for a photoreflective molded product having heat resistance capable of maintaining the characteristics even during use at high temperatures. SOLUTION: This polyester resin composition is characterized in that the polyester composition is used for the photoreflective molded product in which the photoreflective metal layer is formed on the molded product obtained from the polyester resin composition and the composition comprises (B) a polyalkylene naphthalate resin in an amount of 5-100 pts.wt. based on 100 pts.wt. of (A) a polybutylene terephthalate resin.
