Abstract: Disclosed herein is a composition including (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 obtained 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. Further disclosed herein are an aqueous coating composition including the composition, a layer formed from the aqueous coating composition, and a substrate coated with the layer.
