Abstract:
Solid pigment preparations comprising as essential constituents (A) 45% to 90% by weight of at least one color-conferring component comprising (A1) 5% to 100% by weight of at least one pigment and (A2) 0% to 95% by weight of at least one filler without self color, (B) 5% to 50% by weight of at least one water-soluble surface-active additive from the group of alkylene oxide group containing additives (B1) and alkylene oxide group free additives (B2), the alkylene oxide group containing additive (B1) comprising at least 5% by weight of the pigment preparation, and (C) 0.1% to 5% by weight of an antioxidant and also production and use of the pigment preparations for coloration of macromolecular organic or inorganic materials and also of plastics materials.
Abstract:
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.
Abstract:
An aqueous, low-VOC/SVOC universal pigment preparation is provided, which contains (A) a pigment component; (B) a water-soluble additive containing at least one polyamine B, which is selected from the group consisting of polyvinylamines, poly-C2-C3-alkyleneimines, modified poly-C2-C3-alkyleneimines, melamines, modified melamines, poly-(C2-C4-alkyleneether) amines, polyetheramine polyols, and modified polyetheramine polyols; (C) an additive based on lecithin and/or an anionic additive based on a phosphoric ester and/or phosphonic ester; and (D) optionally further additives customary for producing an aqueous pigment preparation. The aqueous pigment preparation is suitable for coloring coating materials like paints, varnishes or renders, preferably for point-of-sale tinting (POS) or in in-plant tinting systems.
Abstract:
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.
