<p>A flame-retardant (C) of an aromatic phosphoric acid ester of the following formula (I) (5 to 50 parts by weight) and a fluororesin (D) such as a powdery polytetrafluoroethylene (0.05 to 5 parts by weight) are added to 100 parts by weight of a mixture of thermoplastic resins comprising 50 to 95% by weight of an aromatic polycarbonate (A) and 5 to 50% by weight of a styrenic resin (B) comprising at least a rubber-modified styrenic resin: <CHEM> wherein (i) at least one of R<1> to R<4> is a 2,3-dialkylphenyl group, a 3,4-dialkylphenyl group or a 3,5-dialkylphenyl group each substituted with alkyl groups each having 1 to 3 carbon atoms, A is a phenylene group, n denotes an integer of 0 to 5, and R<1> to R<4> contain the dialkylphenyl group and a monoalkylphenyl group in a ratio of the former/the latter is 50/50 to 90/10 (% by weight); or (ii) at least one of R<1> to R<4> is a phenyl group substituted with 1 to 5 alkyl groups each having 1 to 4 carbon atoms, A is 1,3-phenylene group and n denotes an integer of 1 to 5. The flame-retardant (C) may be a mixture of the compound (i) and the compound (ii).</p> |
