The composition having excellent flame retardancy comprises 1-100 parts by weight of a polycarbonate resin and/or a copolyester carbonate having an aliphatic segment and 99-0 parts by weight of an SAN resin and further contains 0.5-40 parts by weight of each of two rubber components, i.e., an ABS resin and a composite rubbery graft copolymer prepared by grafting a vinylic monomer onto a composite rubber composed of polyorganosiloxane and polyalky (meth)acrylate and 1-30 parts by weight of a phosphoric ester compound as a flame retardant. This composition has such an excellent flame retardancy that a thin-wall molding thereof can pass the V or 5V test of UL94. The composition having excellent low-temperature impact resistance comprises 1-99 parts by weight of a polycarbonate resin and/or a copolyester carbonate having an aliphatic segment and 99-1 parts by weight of an SAN resin and further contains 0.5-40 parts by weight of each of the abovementioned two rubber components. The impact resistance is especially remarkable at low temperatures.
