Abstract

An organic pigment, which has been coated by homopolymers or copolymers based on acrylic acid, methacrylic acid and/or alkyl esters thereof on top of a silane film which has itself been adsorbed onto a film of hydrolysed zirconium acetylacetonate, is useful in the warp-free pigmenting of polyolefins.
