Subject matter are aqueous, low-VOC/SVOC universal pigment preparations comprising a pigment component; a water-soluble, nonionic, surface-active additive comprising a copolymer formed from a vinyl monomer and from an ethylenically unsaturated monomer selected from the group consisting of monocarboxylic esters, dicarboxylic esters, monocarboxamides, and dicarboxamides, the vinyl monomer and/or the ethylenically unsaturated monomer containing an N-containing group with pigment affinity; a phosphoric or phosphonic ester, and optionally customary additives. The aqueous pigment preparations are suitable for the coloring of inks, paints, and renders, especially in metering systems at the point of sale or in in-plant tinting systems.

Universal pigment preparations for point-of-sale use

Subject matter are aqueous, low-VOC/SVOC universal pigment preparations comprising a pigment component, a water-soluble, anionic, surface-active additive from the group of the homo- and copolymers of ethylenically unsaturated monocarboxylic or dicarboxylic acids, which may further comprise, in copolymerized form, vinyl monomers containing no acid function, and of the salts of these homo- and copolymers, the homo- and copolymers being at least partly esterified with a polyether alcohol or a derivative thereof, and comprising a phosphoric or phosphonic ester, and optionally customary additives. The aqueous pigment preparations are suitable for the coloring of inks, paints, and renders, especially in metering systems at the point of sale or in in-plant tinting systems.

Disclosed are solid pigment preparations containing (A) 60 to 95 per weight of at least one pigment, (B) 5 to 40 percent by weight of at least one water-soluble anionic surface-active additive from the group of the homopolymers and copolymers of ethylenically unsaturated monocarboxylic acids and/or ethylenically unsaturated dicarboxylic acids which can additionally contain monopolymerized vinyl monomers having no acid function, the alkoxylation products of said homopolymers and copolymers, and the salts of said homopolymers and copolymers and the alkoxylation products thereof, and (C) 0 to 20 percent by weight of at least one nonionic surface-active polyether-based additive as essential components. Also disclosed are a method for the production thereof and methods for dyeing macromolecular organic and inorganic materials.
