Document Type and Number:
Japanese Patent JP3563536
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain the subject composition not yellowing by exposure to light over a long period of time, having a stable color tone and suitable for an trimming part of an automobile, etc., by simultaneously using a specific yellow dyestuff with a light-stabilizer.
SOLUTION: This light resistant polycarbonate-based resin composition is obtained by blending 100 pts.wt. polycarbonate-based resin consisting of (A) 1-100wt.% polycarbonate resin and (B) 0-99wt.% thermoplastic resin capable of mixing and mulling with the component (A), with (C) 0.05-2 pt.wt. light- stabilizer and (D) 0.0005-0.2 pt.wt. yellow dyestuff having a property of changing to white color on exposure to light. Further, it is preferable to use a polybutyleneterephthalate, a polyethyleneterephthalate, an acrylonitrile-EPDM- styrene copolymer or an acrylonitrile-butadiene-styrene copolymer as the component (B), a compound having a benzotriazole, a benzophenone or a piperidine skeleton in molecule thereof as the component (C) and solvent yellow 157 of a color index number as the component (D).
