Abstract: UV- and heat-curable aqueous polyurethane dispersions comprise compounds attached via polyisocyanates and containing UV-polymerizable C=C double bonds, aliphatic diols incorporated by way of isocyanates and having a molecular weight of less than 500 g/mol, compounds attached via isocyanates and containing carboxylic acid or sulfonic acid groups and/or salts thereof, free hydroxyl groups, and compounds containing blocked isocyanate groups. They are suitable for coating heat-stable substrates such as metal substrates and may be used with advantage for automotive clearcoats.

Abstract: The invention relates to aqueous polyurethane dispersions which can be hardened with UV radiation and thermally. Said polyurethane dispersions contain the following: compounds bonded with polyisocyanates, with C=C doubl e bonds that can be polymerised with UV-radiation; aliphatic diols inserted wi th isocyanates, with a molecular weight of less than 500 g/mol; compounds bonde d with isocyanates, with carboxylic acid or sulphonic acid groups and/or salts thereof, free hydroxyl groups and compounds with blocked isocyanate groups. The inventive polyurethane dispersions are suitable for coating thermostable substrates such as metal substrates and can be advantageously used for clear automobile lacquers.
