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.

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.
