  • Patent number: 7452587
    Abstract: A polyester resin composition which comprises 30 to 80 wt % of a polybutylene terephthalate resin (A), 10 to 40 wt % of a polyethylene terephthalate resin (B), 0.1 to 40 wt % of a calcined kaolin (C) having an average particle diameter of 1.5 micro meter or less and 0.1 to 40 wt % of a spherical inorganic filler (D) is excellent in direct metal vapor deposition ability, and a light-reflecting article comprising a molded article from the resin composition and a vapor deposited metal film formed on part or whole of the surface of the molded article provides a high brightness feeling and is free from lowering of the brightness feeling due to shadowing after high temperature exposure, and thus can be suitably used as a housing, a reflector or an extension in an automobile lamp, a lighting apparatus in a household electrical appliance, or the like.
