Abstract
An additive for imparting flame retardancy with an organic resin is provided. This additive does not use environmentally harmful halogen or phosphorus flame retardant which also adversely affects the performance of the product, and this additive satisfies severe flame retardancy requirements at the level equivalent to those employing such flame retardants. Also provided are a flame retardant polycarbonate resin composition adapted for use in producing a product having excellent mechanical properties, moldability, and outer appearance as well as an article molded therefrom. The additive for imparting flame retardancy with an organic resin comprises a silicone compound having phenyl group bonded to silicon atom, an alkali metal sulfonate salt group or an alkaline earth metal sulfonate salt group bonded to silicon atom via a hydrocarbon group (optionally containing a hetero atom), and siloxane bond.
