Abstract
A flame-retardant aromatic polycarbonate resin composition has excellent flame retardancy and high transparency without impairing excellent properties inherent to an aromatic polycarbonate resin, and is free from corroding a molding machine or a processing machine, the flame-retardant resin composition comprising 100 parts by weight of an aromatic polycarbonate resin, 0.01 to 1 part by weight of (a) a perfluoroalkane-sulfonic acid alkali salt and 0.02 to 2 parts by weight of (b) a halogenated triaryl phosphate of the formula [1], ##STR1## wherein each of Ar.sup.1, Ar.sup.2 and Ar.sup.3 is independently an aromatic hydrocarbon, and at least one halogen atom is substituted on ring-forming carbon of each aromatic hydrocarbon group.
