Beschreibung
Zusammenfassung:	The present invention relates to a composition comprising (i) at least one polyurethane (1) carrying ethylenically unsaturated groups and COOH groups, which COOH groups are at least partly in the form of a salt group thereof, which polyurethane is obtainable by the reaction of at least one polyol (B1) carrying at least one COOH group, at least monoalcohol (B2) carrying at least one ethylenically unsaturated group, optionally at least polyol (B3) carrying at least one ethylenically unsaturated group and no COOH group, at least one polyol (B4) carrying no ethylenically unsaturated group and no COOH group, at least one polyisocyanate (A1) carrying at least one ethylenically unsaturated group, optionally at least one polyisocyanate (A2) carrying no ethylenically unsaturated group, and optionally at least one compound (C1) carrying at least one NH2 group and no OH group, wherein the equivalent ratio of ethylenically unsaturated groups of polyisocyanate (A1)/ethylenically unsaturated groups of components (B1), (B2)
