PROBLEM TO BE SOLVED: To provide a colored flame-retardant resin composition which gives a thin-walled molding hardly staining a metal mold and excellent in flame retardancy, colorant dispersibility, flowability, and impact resistance. SOLUTION: Pellets of an uncolored flame-retardant resin composition of 100 pts.wt. comprising an aromatic polycarbonate resin (A), a rubber-modified styrene resin (B), at least one organic phosphorus compound oligomer (C), and a fluoropolymer (D) is mixed with 0.001-5 pts.wt. organic compound (E) having a boiling point of 80-200 deg.C at 760 mmHg and 0.0001-10 pts.wt. colorant (F). The resultant mixture is melt kneaded on an extruder having a vent hole while being degassed through the vent hole. Thus, a colored flame-retardant polycarbonate resin composition containing 500 wt.ppm or lower component E and 3,000 wt.ppm or lower lubricant (G) is produced. |
