Abstract: Solid pigment preparations comprising as essential constituents (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 polyurethanes and (C) from 2.5% to 35% by weight of at least one nonionic water-soluble surface-active additive (C1) based on polyethers and/or of an anionic water-soluble additive other than additives (B) which is based on polymers of ethylenically unsaturated carboxylic acids (C2), and also production and use of the pigment preparations for coloration of macromolecular organic and inorganic materials and also of plastics.

Abstract: Solid pigment preparations comprising as essential constituents (A) from 60% to <90% by weight of at least one pigment, (B) >10% to 40% by weight of at least one anionic surface-active additive based on acid phosphoric, phosphonic, sulfuric and/or sulfonic esters of polyalkylene oxides or of reaction products of alkylene oxides with aliphatic alcohols, with phenol or naphthol, which may each be alkyl substituted if desired, with aliphatic or aromatic amines or with aliphatic carboxylic acids or carboxamides or on salts thereof, the fraction of the phosphorus-containing additive in a mixture of phosphorus- and sulfur-containing additives being not less than 50% by weight, and (C) from 0% to <30% by weight of at least one nonionic surface-active additive based on polyethers, with the proviso that component (B) is a phosphoric and/or phosphonic ester when the fraction of component (C) is 0% by weight, are made and used for pigmenting macromolecular organic and inorganic materials.

Abstract: Pigment preparations including as essential constituents (A) from 60 to 90% by weight of at least one pigment, (B) from 10 to 40% by weight of at least one nonionic surface-active additive based on polyethers, and (C) from 0.1 to 10% by weight of at least one anionic surface-active additive based on sulfonates, sulfates, phoshonates or phosphates, the sum total of the weight percentages not exceeding 100% by weight, are prepared and used for pigmenting macromoleular organic and inorganic materials.

Abstract: Pigment granules having an average particle size from 50 to 5000 ?m and a BET surface area ?15 m2/g, including as essential constituents (A) from 60 to 90% by weight of at least one pigment and (B) from 10 to 40% by weight of at least one nonionic surface-active additive based on polyethers, are prepared and used for pigmenting macromolecular organic and inorganic materials.

Abstract: Solid pigment preparations containing the following ingredients as substantial components: (A) 60–85 wt. % of at least one organic pigment, (B) 0.1–15 wt.

Abstract: Process for preparing pigments by applying a polymerizable mixture to a surface, orienting the liquid crystals present in the mixture, polymerizing the mixture, detaching the polymer film from the surface and comminuting the polymer film to form pigment particles, wherein the polymerizable mixture comprises:a.sub.1) at least one chiral liquid-crystalline polymerizable monomer ora.sub.2) at least one achiral liquid-crystalline polymerizable monomer and a chiral compound, and additionallyb) a polymeric binder and/or monomeric compounds which are converted by polymerization into a polymeric binder and/or a dispersion auxiliary.

Abstract: Luster pigments obtainable by treating titania-coated silicate-based platelets at from 400.degree. to 900.degree. C. with a gas mixture comprising a vaporized organic compound and ammonia are useful for coloring paints, inks, including printing inks, plastics, glasses, ceramic products and decorative cosmetic preparations.
