Summary: | The present invention relates to an aqueous polyurethane-polyacrylate dispersion, obtainable by radical polymerization of a component A), comprising an ethylenically unsaturated compound, at least in the presence of a component B), comprising water and a polyurethane resin, obtainable by reaction of the following synthesis components I), comprising at least one aliphatic, cycloaliphatic, araliphatic and/or aromatic compound having at least two or more isocyanate groups, II), comprising at least one polycarbonate polyol having an average molecular weight of 500 to 3000 g/mol, III), comprising at least one anionically hydrophilizing compound which has at least one OH- or NH-functional group and comprising a carboxyl and/or carboxylate group, IV), comprising at least one polyol and/or polyamine having an average molecular weight of between ≥62 and ≤500 g/mol, and optionally V), comprising at least one or more monoalcohols and/or monoamines, the radical polymerization being initiated using a hydrophilic initiator. |
