    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.
