An object of the present invention is to provide an additive composition capable of imparting excellent flame retardancy and heat resistance to synthetic resins. The additive composition contains (A) component: a bromine-type flame retardant, (B) component: antimony oxide, (C) component: the compound and (D) component: phenolic antioxidant shown by following formula (1). In the formula, R 1 , R 2 , R 3 and R 4 each independently represent a hydrogen atom or a monovalent hydrocarbon group having 1 to 4 carbon atoms. It is preferable that R< 1 >, R< 2 >, R< 3 >, and R< 4 > in Formula (1) are each independently a hydrogen atom or a C1-C4 linear alkyl group. |
