Abstract

The present invention provides a curable polyurethane polymer containing in copolymerized formA) from 10 to 60% by weight of at least one hydroxyl-containing prepolymer having at least one &agr;,&bgr;-ethylenically unsaturated double bond,B) from 0.1 to 30% by weight of at least one compound having at least one isocyanate-reactive hydroxyl group and/or primary or secondary amino group and, in addition, at least one polar functional group per molecule,C) from 0.1 to 30% by weight of at least one compound selected from diamines, polyamines and mixtures thereof,D) from 0 to 10% by weight of at least one further compound other than A), B), C) and E) having at least two isocyanate-reactive groups, which are hydroxyl groups and mixtures of hydroxyl groups with primary and/or secondary amino groups,E) from 0 to 20% by weight of at least one compound having an isocyanate-reactive group,F) from 10 to 65% by weight of at least one compound having at least two isocyanate groups,and the salts thereof, wherein the ratio of isocyanate group equivalents of component F) to equivalents of isocyanate-reactive groups of components A) to E) is in a range from 0.4:1 to 0.9:1, polymer dispersions compri…
