Amphoteric water-soluble polymers which contain a) from 90 to 30% by weight of acrylic acid and/or methacrylic acid b) from 10 to 60% by weight of a compound of the formula <IMAGE> in which R1 is hydrogen or methyl, R2 and R3, which are identical or different, are methyl or ethyl, and X is an optionally branched alkylene radical having 1 to 5 carbon atoms, and optionally up to 50% by weight of acrylamidomethylpropanesulphonic acid and up to 10% by weight of a further ethylenically unsaturated compound, the molecular weight of these polymers measured at a pH of 8.0, being less than 100,000, are used as grinding assistants or dispersants in the preparation of highly concentrated, aqueous pigment slurries. |
