Abstract: Radiation-curable coating compositions are disclosed which contain one or more amide acrylate compounds of the general formula: ##STR1## wherein X, Y and Z may each independently be H, alkyl, aryl, acrylyloxyalkyl, acrylyloxy aliphatic ester or acrylyloxy aliphatic ether, provided that X, Y and Z together have two, three or four acrylyloxy groups. The compositions are highly radiation-sensitive and very fast curing and form mar-resistant protective and decorative film coatings which are particularly useful as UV-cured overprint varnishes.
