Abstract
Polymerizable compounds based on N-acylamido-piperazines are provided. Such compounds have the formula: ##STR1## wherein: R.sup.1, R.sup.2, and R.sup.3 are each independently selected from the group consisting of hydrogen and lower alkyl, PA1 B is a linking group selected from the group consisting of carbonyl, sulfonyl, amide, and carboxyl; PA1 n is ore or zero; PA1 R.sup.4 is a radical selected from the group consisting of a higher aliphatic group (i.e. at least four carbon atoms, preferably from about 6 to about 50 carbon atoms), a substituted higher aliphatic group, an alicyclic group, a heterocyclic group, a non-benzenoid aromatic group, and a substituted aromatic group. These compounds can be incorporated into a polymerizable composition. The compound is preferably present in said composition in a major amount on a mole percent basis of the polymerizable monomers. These polymerizable compositions are useful as coatings, particularly in formulations containing a photoinitiator susceptible to ultra-violet radiation. The coating is exposed to ultra-violet radiation sufficient to cause the compound to polymerize and thus cure the coating.
