ABSTRACT OF THE DISCLOSURE Storage-stable, radiation-hardenable, NCO-free aqueous emulsions based on ionic urethane-urea acrylates is disclosed. The emulsions are made up of partially acrylated cycloaliphatic polyisocyanates which have been acrylated by a hydroxyalkyl acrylate (to the extent of 10-60 equivalent-% NCO). These products are then reacted with polyhydroxy compounds (to the extent of 20-75 equivalent-% NCO), and then with sodium salts of aminocarboxylic acids to the extent of 5-15 equivalent-% NCO), and finally they are reacted with water and/or aliphatic diamines (said aliphatic diamines in amounts corresponding to 1-5 equivalent-% NCO). The reaction product of the cycloaliphatic polyisocyanate with the hydroxy acrylate compounds and the polyols is taken up into ordinary organic solvents, and these solvent-containing reaction products are converted with aqueous solutions of sodium salts of aminocarboxylic acids and then with water and/or with an amount of aliphatic diamines corresponding to 1-5 equivalent-% NCO, whereafter the organic solvent is distilled off.
