ABSTRACT:
The object of the present invention is to providea flame-retardant thermoplastic resin composition, which comprises:100 parts by weight of a thermoplastic resin (A),0.1 to 30 parts by weight of a polyorganosiloxane-containing graft copolymer (B) obtained by polymerizing, in at least one stage, a monomer (B-3) comprising a polyfunctional monomer (B-2) containing at least two polymerizable unsaturated bonds within the molecule thereof, and/or a vinyl monomer (B-4) in the presence of polyorganosiloxane particles (B-1),0.0005 to 5 parts by weight of at least one metal salt (C) selected from the group consisting of alkali metal salts and bivalent or further polyvalent metal salts, and0.05 to 2 parts by weight of a fluororesin (D).
