A mixture Ia which comprises a composition Ia consisting of n a) 1 to 95% by weight of a solid III, preferably a basic solid III, having a primary particle size of 5 nm to 20 microns, and n b) 5 to 99% by weight of a polymeric mass IV obtainable by polymerizing n b1) 5 to 100% by weight, based on the mass IV of a condensation product V of n α) at least one compound VI which is capable to react with a carboxylic acid or a sulfonic acid or a derivative thereof or a mixture of two or more thereof, and n β) at least one mole per mole of the compound VI of a carboxylic acid or a sulfonic acid VII which exhibits at least one radically polymerizable functional group, or a derivative thereof or a mixture of two or more thereof and n b2) 0 to 95% by weight, based on the mass IV, of a further compound VIII having an average molecular weight (number average) of at least 5000 and having polyether segments in the main or side chain, n wherein the proportion by weight of the composition IIa in the mixture Ia is 1 to 100% by weight. |
