| abstract |
The present invention provides a resin composition having a low specific gravity, a high rigidity, a molding cycle property, and an excellent flame retardancy without blending a filler such as talc. A flame retardant composition containing, as essential components, a (poly) phosphate compound represented by the following general formula (1) and a (poly) phosphate compound having a specific structure and a silicon-containing compound in a synthetic resin. And a flame retardant resin composition containing a cyclic organophosphate metal salt compound having a specific structure as a crystal nucleating agent. In the formula, X 1 is ammonia or a triazine derivative having a specific structure. [Selection figure] None |
