POLYCARBONATE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a polycarbonate resin composition that has excellent heat stability, high impact strength and light reflection properties, particularly having improved wavelength dependability of optical reflectance. SOLUTION: The objective polycarbonate resin composition comprises (a) 100 pts.wt. of a polycarbonate resin including 99-50 wt.% of an aromatic polycarbonate resin and 1-50 wt.% of a copolycarbonate resin bearing a specific structural unit, (b) 3-30 pts.wt. of titanium oxide, (c) 0.005-1 pts.wt. of a fluorescent brightening agent. This invention also relates to light reflection plates produced by molding the resin composition.
