Radiation-curable coating compositions containing amide acrylate compounds
First Claim
1. Radiation polymerizable, highly radiation-sensitive composition curable to form a film comprising from about one to 99 percent by weight of one or more amide acrylate compounds having one nitrogen atom and being of the formula:
- ##STR6## wherein X, Y and Z may each independently be H, alkyl, aryl, acrylyloxyalkyl, acrylyloxy aliphatic ester formed by reaction of acrylating material with hydroxyl terminated aliphatic ester-containing intermediate resulting from the reaction of inner ester of hydroxy carboxylic acid and amino alcohol, or acrylyloxy aliphatic ether, provided that X, Y and Z together have two, three of four acrylyloxy groups.

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.
