PROBLEM TO BE SOLVED: To provide flamed-retarded polycarbonate resin compositions which excel in mechanical properties, weatherability and flame retardance and, at the same time, excel in mold depositing properties. SOLUTION: Flame-retarded polycarbonate resin compositions comprise (a) 100 pts.wt. aromatic polycarbonate, (b) 0.5-40 pts.wt. nitrogen-containing phosphate ester represented by the formula (wherein R1 is a 1-6C alkylene group, a halogen substituted alkylene group, an arylene group or a halogen substituted arylene group; R2 and R3 are each hydrogen, a 1-6C alkyl group or an aryl group and R2 and R3 may be linked with an alkylene group; and Ph is an aryl group or a halogen substituted aryl group and the aryl group excludes the one having an alkyl group in the aromatic ring), (c) 0.01-5 pts.wt. polyfluoroethylene, (d) 0.5-30 pts.wt. impact resistance improver, and (e) 0.01-2 pts.wt. ultraviolet absorber.
