<p><P>PROBLEM TO BE SOLVED: To provide a resin composition which decreases the mold stain when a light reflector part made of a resin is formed by injection molding or the like, and has excellent mold releasability and heat resistance, and in which a resin molding that controls the bleed-out to a molding surface highly can be obtained, thereby the cissing phenomenon at the time of the undercoat can be controlled, even if exposed under the high temperature atmosphere, the holding of the high luminance feeling can be performed, and the holding of the shape is excellent in a molding having a thin thickness. <P>SOLUTION: The thermoplastic polyester resin composition includes: 70-95 pts.mass of a resin composition (A) that compounds a polybutylene terephthalate resin and (B) a polyethylene terephthalate resin so that the mass ratio of (A)/(B) may become 70/30-85/15; 5-30 pts.mass of an inorganic filler; and 0.1-1 pt.mass of a release agent (D) based on 100 pts.mass of the total of (A)-(C), and satisfies specific conditions in a molded product that is formed by injection molding. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
