Abstract
A polycarbonate resin composition comprising 100 parts by weight of a polycarbonate resin (component A), 0.01 to 10 parts by weight of at least one ultraviolet light absorber (component B) selected from the group of a specific cyclic imino ester, and 0.01 to 1 part by weight of a fatty acid ester compound (component C) which is an ester of a polyhydric alcohol and an aliphatic carboxylic acid and has a molecular weight of 500 to 2,000 g/mol, as well as molded articles thereof.The polycarbonate resin composition provides molded articles having excellent transparency, color and resistance to ultraviolet radiation, is excellent in heat stability at the time of molding and releasability and fully suppresses the production of a deposit on a metal mold.
