POLYESTER RESIN COMPOSITION

PROBLEM TO BE SOLVED: To provide a polyester resin composition which gives a heat-resistant molded article (a light-reflecting body) which, even when a light-reflecting metallic layer is vapor-deposited thereon directly without forming thereon an undercoating layer, exhibits good brightness, high re...

More Information
Summary:PROBLEM TO BE SOLVED: To provide a polyester resin composition which gives a heat-resistant molded article (a light-reflecting body) which, even when a light-reflecting metallic layer is vapor-deposited thereon directly without forming thereon an undercoating layer, exhibits good brightness, high reflectance, and good adhesion to a metal and can retain these characteristics even under high-temperature use. SOLUTION: This polyester resin composition, used for preparing a light- reflecting molded article by forming a light-reflecting metallic layer on a molded article obtained from the composition, is prepared by compounding (A) 100 pts.wt. polybutylene terephthalate resin with (B) 5-100 pts.wt. polyethylene terephthalate resin and (C) 1-100 pts.wt. polyalkylene naphthalate resin.
