Abstract:
1. A solid pigment preparation comprising as essential constituents: (A) from 60% to <90%, by weight of the preparation, of at least one pigment, (B) >10% to 40%, by weight of the preparation, of at least one anionic surface-active additive, based on (1) acid phosphoric, phosphonic, sulfuric and/or sulfonic esters of polyalkylene oxides, (2) acid phosphoric, phosphonic, sulfuric and/or sulfonic esters of reaction products of alkylene oxides with aliphatic alcohols, (3) acid phosphoric, phosphonic, sulfuric and/or sulfonic esters of reaction products of alkylene oxides with phenol or naphthol, which may each be optionally alkyl substituted, (4) acid phosphoric. phosphonic, sulfuric and/or sulfonic esters of reaction products of alkylene oxides with aliphatic or aromatic amines, (5) acid phosphoric, phosphonic, sulfuric and/or sulfonic esters of reaction products of alkylene oxides with aliphatic carboxylic acids or carboxamides, (6) salts of the esters (1)-(5), and wherein the fraction of the phosphorus-containing additive in a mixture of phosphorus- and sulfur-containing additives is not less than 50% by weight, and (C) from 0% to <30%, by weight of the preparation, 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.
