Abstract: A process for the preparation of pigment compositions, which comprises adding to the pigments an aqueous solution of an alkali metal silicate and a polyethylene dispersion and working up the mixture in a manner usual for pigments. The pigment compositions thus obtained are useful for coloring polyethylene films and sheets or for dyeing polyolefins in a spinning solution. The compositions show an excellent pigment distribution and tinctorial strength which is substantially better than those of compositions prepared without the addition of alkali metal silicates.
Abstract translation: 一种制备颜料组合物的方法，其包括向颜料中加入碱金属硅酸盐和聚乙烯分散体的水溶液，并以通常用于颜料的方式处理混合物。 由此获得的颜料组合物可用于着色聚乙烯薄膜和薄片或用于在纺丝溶液中染色聚烯烃。 组合物显示出优异的颜料分布和着色强度，其明显优于不加入碱金属硅酸盐制备的组合物。

Abstract: Preparations of insoluble colorants, especially pigments, are obtained by distributing the colorant in molten polypropylene wax having a viscosity of 0.5 to 5 Pa.s, determined at 170 DEG C., and an isotactic proportion of 40 to 90% by weight. These preparations are easily dispersible in polyolefins and especially useful for dyeing polypropylene in the mass.
