Abstract:
The present invention relates to radiation-curable coating compositions based on tin-free aqueous polyurethane dispersions based on polyurethane acrylates (i), characterized in that the polyurethane acrylate (i) comprises as builder componentsA) one or more compounds with at least one group which is reactive towards isocyanate and at least one unsaturated group which can undergo free radical polymerization,B) one or more compounds which differ from A) and have at least one group which is reactive towards isocyanate,C) one or more compounds with at least one group which is reactive towards isocyanate and additionally at least one group having a hydrophilizing action,D) one or more organic polyisocyanates,which are reacted in the presence ofF) bismuth(III) salt(s) andG) an acid having a pKa of
