  Curable, ethylenically unsaturated compositions based on an ester groups-containing compound having excellent fire retardant properties as a result of the incorporation therein of a fire retardant amount of N,N'-ethylene bis(sali- cylideneiminato)-Fell and/or the oxidation product derived therefrom. Preferably, use is made of a fitter in an amount of 2 to 60 per cent by weight, calculated on the mixture of filler and components taking part in the curing process in the presence of said iron compound of 0,1 to 5 per cent by weight, calculated on the mixture of fire retardant additive and components taking part in the curing process. An important group of said ethylenically unsaturated compositions are unsaturated polyester resins which are copolymerized with an unsaturated monomer for use in castings, laminated products and other reinforced articles.

  基于含酯基团化合物的可固化乙烯基不饱和组合物，由于加入了一定量的 N,N'-乙烯双(水杨-亚烷基亚氨)-Fell 和/或由其衍生的氧化产物，因此具有优异的阻燃性能。最好使用 2%至 60%（以重量计）的填充剂，以填充剂和参与固化过程的组分的混合物计算，其中存在 0.1%至 5%（以重量计）的铁化合物，以阻燃添加剂和参与固化过程的组分的混合物计算。上述乙烯基不饱和组合物的一个重要类别是不饱和聚酯树脂，它与不饱和单体共聚，用于铸件、层压制品和其他加固制品。
