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.

Solid pigment preparations comprising as essential constituents

Solid pigment preparations containing water-soluble surface-active polyurethane-base additives

A process for producing a solid pigment preparation in the form of granules which comprises atomizing a suspension comprising (A0) 30% to 90% of a solvent component, (A1) 2% to 60% of a pigment component; (A2) 0% to 50% of a first filler component, and (A3) 10% to 70% of a surface-active additive component based on the sum of the components (A1) and (A2); contacting formed droplets with a gas stream having a predetermined temperature to dry the droplets to obtain granules having a predetermined residual moisture content, the droplets are exposed to an aerosol comprising a solid second filler component; and separating the granules from the gas stream.

Producing a solid pigment preparation in the form of granules by spray drying
