Abstract
A flame-retardant resin composition comprising (A) at least one polymer resin selected from the group consisting of thermoplastic polyesters and thermoplastic polycarbonates and, per 100 parts by weight of the polymer resin, (B) 0.1 to 30 parts by weight, as the weight of the halogen element, of an organic halogen compound, and (C) 0.1 to 20 parts by weight, as the weight of the antimony element, of antimony trioxide treated with an alkoxysilane compound. The composition may further comprise up to 30 parts by weight of an organic acid ester compoundf and/or up to 200 parts by weight of a filler, per 100 parts by weight of the polymer resin.
