Polymerizable compounds based on N-acylamido-piperazines are provided. Such compounds have the formula: <IMAGE> wherein: a, b, c and d are independently 0 or 1 and the sum of a, b, c and d is at least 3. R1, R2, and R3 are hydrogen and/or lower alkyl, B1, B2, B3, and B4 are independently carbonyl, sulfonyl, amide, or carboxyl; m, n, x, and y are independently one or zero; R23 is a group selected from, substituted and unsubstituted phenyl and phenonyl. These compounds are particularly useful as polymerizable monomers in radiation curable coatings. The compound preferably has at least one group <IMAGE> substituted on R23 wherein M is H or a counterion to the carboxyl group which can be present in place of a <IMAGE> group./!
