  The present invention relates to aqueous polymer compositions comprising in dispersed form at least one polyurethane (meth)acrylate A and at least one compound B having a molecular weight of below 1000 g/moland having on average more than two ethylenically unsaturated double bonds per molecule. The invention also relates to the use of the aqueous polymer compositions for producing coatings. The polyurethane (meth)acrylates A are constructed from: A1an isocyanate component A1comprising: A1aat least one polyisocyanate obtainable by oligomerization of at least one diisocyanate and having an average isocyanate functionality of at least 2.5, the diisocyanate having at least one saturated alicyclic structural unit; and A1bat least one diisocyanate selected from saturated aliphatic and saturated alicyclic diisocyanates; A2as component A2, at least one compound which has at least one ethylenically unsaturated double bond in the form of an acrylic or methacrylic group, and also has at least one functional group F which reacts with an isocyanate group to form a covalent bond; A3at least one neutral polyol component A3 comprising A3aat least one aliphatic, polymeric polyol having an average OH functionality in the range from 1.5 to 2.5; A3bat least one low molecular weight diol compound having a molecular weight of not more than 400g/mol and selected from saturated aliphatic and saturated alicyclic diols; A4as component A4, at least one compound which has at least one ionic or ionizable group I' and at least one functional group F' which reacts with an isocyanate group to form a covalent bond; and optionally A5 as component A5, at least one poly-C2-C3 alkylene ether compound having an average OH functionality in the range from 0.9 to 1.2.
