The invention relates to aqueous preparations containing: i) at least one hydrophilic particulate polymer (P1), presented as an aqueous dispersion, which consists essentially of monoethylenically unsaturated monomers with a water solubility of between 10 g/l and 100 g/l (at 25 DEG C and 1 bar); and ii) at least one hydrophobic particulate polymer (P2), presented as an aqueous dispersion, which consists essentially of ethylenically unsaturated monomers with a water solubility of less than 10 g/l (at 25 DEG C and 1 bar). The glass transition temperature (TG1) of the polymer (P1) differs from the glass transition temperature (TG2) of the polymer (P2) by less than 10 K. |
