Abstract
Abstract A flame-retardant consisting of two specified components and a flame-retardant resin composition having the flame-retardant blended with a thermoplastic resin are provided, which flame-retardant is composed of (A) a reaction product of cyanuric chloride with a diamine and (B) ammonium polyphosphate or polyphosphoric acid amide, the ratio of (A) to (B) being 0.1 to 10, and which flame-retardant resin composition has the flame-retardant blended with a thermoplastic resin in a quantity of 1 to 50% by weight based upon the weight of the composition.
