The invention relates to the microsuspension polymer A' with a mean particle diameter of between 0.08 and 100 mu m, consisting of components A11 to A13, the total weight of which amounts to 100 weight percent, where a11 is between 0.05 and 20 weight percent of ethylenically unsaturated monomers with free acid groups as component A11, a12 is between 80 and 99.95 weight percent of copolymerisable monomers the homopolymers of which are free of base groups as component A12, and a13 is between 0 and 10 weight percent cross-linking monomers as component A13. |
