Aqueous radiation curable dispersions based on polyurethane acrylates (i) containing as structural components A) one or more oligomeric or polymeric compounds with at least one isocyanate reactive group and at least one radical copolymerizable group, B) if necessary one or more monomeric compounds other than A with a hydroxy function and at least one (meth) acrylate, C) polyesters group which can be obtained from C1) aliphatic diols with 2 to 4 carbon atoms between the two OH and / or functions the aliphatic triols and C2) aromatic di- and / or tricarboxylic acids, D) where appropriate polyols other than A to C, E) one or more compounds with at least one isocyanate-reactive group and additionally non-ionic, ionic or trained groups for the formation of ionic groups, which act in a dispersing manner for the dispersion of polyurethane, F) organic polyisocyanates, G) if necessary compounds other than A to E with at least one isocyanate reactive group. |
