The dispersions comprise the reaction product of a) one or more polyisocyanates of which at least one polyisocyanate is an oligomeric polyisocyanate of hexamethylene diisocyanate with urethane, biuret, iminooxadiazindione and/or isocyanurate structural units, b) one or more monohydroxy-functional compounds containing (meth)acryloyl groups, c) at least one component c1), which has a hydrophilising effect on the basis of incorporated (potentially) ionic groups and comprises at least one further isocyanate-reactive group and/or at least one component c2) which contains non-ionically hydrophilically acting groups and comprises at least one further isocyanate-reactive group, d) one or more difunctional and/or polyfunctional amines or hydroxyamines as chain extender, and e) optionally other monomeric, oligomeric and/or polymeric substances, which may optionally also contain further unsaturated groups.
