PURPOSE: A thermoplastic resin composition without showing partial increase of burning time and lowering mechanical physical properties during high speed injection molding by adding a suitable compatibilizing agent to a composition comprising polycarbonate resin, a rubber modified styrene based graft copolymer, a styrene based copolymer, a phosphorous compound and fluorine polyolefin is provided, which is well balanced between excellent stress crack resistance, thermal stability, heat resistance, workability and appearance without suffering a juicing phenomenon. CONSTITUTION: The resin composition comprises (A) 45 to 95 parts by weight of thermoplastic carbonate resin, (B) 1 to 50 parts by weight of a styrene based graft copolymer, (C) 0.5 to 50 parts by weight of a styrene based copolymer or mixtures thereof, (D) 0.5 to 30 parts by weight of a compatibilizing agent, (E) 0.5 to 20 parts by weight of a phosphorous acid compound of formula (1) or mixtures thereof based on 100 parts by weight of the composition (A) + (B) + (C), and (F) 0.05 to 5 parts by weight of fluorinated polyolefin resin having an average particle size of 0.05 to 1,000 micrometer and a density of 2.0 to 2.3 g/cm3. In formula, R1, R2, R4 and R5 are each C6-20 aryl or alkyl substituted C6-20 aryl; R3 is C6-30 aryl or alkyl substituted C6-30 aryl derivatives and M represents a number average polymerization degree of 0 to 5.
