Abstract

The purpose of the present invention is to provide a flame-retardant polycarbonate resin composition which contains phosphorus-free flame-retardant(s), has an excellent impact resistance, an excellent heat resistance as well as an excellent moldability, and can satisfy a severe flammability level. According to the present invention, there is provided a flame-retardant polycarbonate resin composition which comprises (A) 100 parts by weight of an aromatic polycarbonate resin, (B) 0.01-5 parts by weight of an organic sulfonic acid metal salt, (C) 0.01-5 parts by weight of a fluorinated polyolefin, (D) 0.2-20 parts by weight of a diene-containing multi-layered polymer, and wherein the content of a phosphorus-containing flame-retardant is less than 0.5 parts by weight.
