Beschreibung
Zusammenfassung:	The present invention relates to radiation-curable, aqueous dispersions based on polyurethane acrylates (i), which are characterized in that the polyurethane acrylate (i) comprises, as formation components, A) one or more aromatic polyepoxy(meth)acrylates having an OH number of 20 to 300 mg KOH/g of substance, C) one or more oligo- or polyesters containing unsaturated fatty acids having an OH number of 15 to 300 mg KOH/g of substance and an iodine number of greater than 50 g of I/100 g of substance, E) one or more compounds having at least one group reactive toward isocyanate and additionally at least one hydrophilizing group, and F) one or more organic polyisocyanates, to a process for production thereof, to the use of the coating compositions as coating materials and/or adhesives, and to articles and substrates provided with these coating materials and/or adhesives.
