Abstract: A pigment dispersion and its use for the preparation of coating compounds are described. The dispersion contains a pigment, solvent and pigment dispersing agent. The pigment dispersing agent is a copolymer containing OH groups, obtainable by the reaction of:(A) 80 to 95% by weight of a copolymer of:(a) 0.5 to 40% by weight of N,N-di-Cl to 4-alkylamino-C.sub.1 to .sub.8 -alkyl(meth)acrylamides and/or a mixture of N,N-di-C to 4-alkylamino-C.sub.1 to 8 -alkyl(meth)acrylates and N-substituted (meth)acrylamides and/or (meth)acrylamide in which the ratio of amino(meth)acrylates to amido(meth)acrylates should be in the range of from 1:2 to 2:1,(b) 10 to 40% by weight of hydroxy-C.sub.2-8 -alkyl (meth)acrylates and(c) 20 to 89.5% by weight of copolymerizable, .alpha., .beta.-olefinically unsaturated compounds with(B) 5 to 20% by weight of a polyisocyanate containing unmasked and optionally also masked isocyanate groups as well as biuret, urethane or isocyanurate groups.

Abstract: Modified polyester imides, hardenable by energy-rich radiation and containing an acrylic or methacrylic ester group having a hydroxyl group, said ester group being linked to the polyester imide molecule by way of an oxygen atom that is located on the carbon atom adjacent to the carbon atom carrying said hydroxyl group, as well as a process for their production and their use for the insulation of electric wires.
