Abstract:
1. A solid pigment preparation consisting essentially of (A) from 60% to 95% by weight of at least one pigment, (B) from 2.5% to 35% by weight of at least one water-soluble surface-active additive based on a polyurethane having an average molecular weight of from 500 to 250,000 and which is based on a reaction product of polyfunctional isocyanate (Ba) with an organic compound (Bb) comprising at least two isocyanate-reactive hydroxyl groups per molecule, wherein the organic compound (Bb) is selected from the group consisting of a polyetherdiol, a polyesterdiol, a lactone-based polyesterdiol, a diol having up to 12 carbon atoms, a triol having up to 12 carbon atoms, a dihydroxy carboxylic acid, a dihydroxy sulfonic acid, a dihydroxy phosphonic acid, a polycarbonatediol, a polyhydroxyolefin and a polysiloxane having on average at least two hydroxyl groups per molecule; and (C) from 2.5% to 35% by weight of at least one nonionic water-soluble surface-active additive (C1) based on polyether or of an anionic water-soluble surface-active additive other than additives (B) which is based on polymers of ethylenically unsaturated carboxylic acid (C2) which is a homopolymer of an ethylenically unsaturated dicarboxylic acid, or a copolymer of an ethylenically unsaturated dicarboxylic acid, optionally comprising an interpolymerized vinyl monomer with no acid function, wherein the non-ionic additive (C1) is a reaction product of an alkylene oxide with an amine.
