PURPOSE: A thermoplastic flame retardant resin composition and a product prepared by using the composition are provided, to improve the flame retardancy by employing copper compounds without adding char compounds. CONSTITUTION: The composition comprises 100 parts by weight of a rubber-modified styrene-acrylonitrile copolymer resin which comprises (a1) 20-90 wt% of a styrene-acrylonitrile grafted copolymer resin whose rubber content is 10-68 wt% and whose acrylonitrile content except the rubber component is 18-65 wt%, and (a2) 10-80 wt% of a styrene-acrylonitrile grafted copolymer resin whose acrylonitrile content is 18-65 wt%; 2-30 parts by weight of an aromatic phosphate ester compound; and 0.01-20 parts by weight of at least one copper compound selected from the group consisting of oxides, sulfides, chlorides, fluorides, phosphates, sulfates, nitrates and salts of organic acids including monovalent or divalent copper. Optionally the composition comprises further 0-60 parts by weight of a polyphenylene ether resin.
