    摘要： The present invention provides a composition that can impart a drip preventing effect together with an excellent heat release suppressing effect to a resin, and that enables the resin to exhibit an excellent color tone, by being mixed with the resin. The composition includes a component (A) and/or a component (B), and a component (C). It is preferable that the composition of the present invention contains the component (C) in an amount of 0.1 to 50 parts by mass relative to 100 parts by mass of a total of the components (A) and (B).
    The component (A) is a (poly)phosphate compound represented by General Formula (1).

    The component (B) is a (poly)phosphate compound represented by General Formula (3).

    The component (C) is a hydrous magnesium silicate.

    摘要： An object of the present invention is to provide an additive composition that can impart excellent thermal resistance and flame retardancy to a synthetic resin. The additive composition contains a bromine-based flame retardant as a component (A), an antimony oxide as a component (B), a compound expressed by the formula (1) below as a component (C), and a phenolic antioxidant as a component (D).

    In the formula (1), 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 the formula (1) each independently represent a hydrogen atom or a linear alkyl group having 1 to 4 carbon atoms.
