摘要： The present invention provides a flame-retardant which is not only excellent in flame-retarding property but also devoid of lowering moisture-resisting property specially in the course of molding of a resin so that the flame-retardant has little limitation for the molding method, the molding conditions and the intended use thereof. What is characterized is a flame-retardant comprising (a) an aliphatic amine salt of a phosphoric ester with 2-25 carbon atoms in the ester moiety thereof having a melting point of at least 100° C. but not more than a molding temperature of a thermoplastic resin and (b) a salt of phosphoric and/or polyphosphoric acid, the proportion of the component (a) to the component (b), i.e. (a)/(b) being 1/2-5/1 by weight ratio. In case a polyolefin resin is incorporated with this flame-retardant, the resultant resin composition achieves such an outstanding merits that the composition is not only excellent in flame-retarding property but also devoid of lowering moisture-resisting property especially in the course of molding of the resin composition so that the composition has little limitation for the molding method, the molding conditions and the intended use thereof.
