Abstract
Provided are compounds having the formula: ##STR1## wherein: R.sup.1 and R.sup.2 are independently selected from the group consisting of a hydrogen atom, an aliphatic group, a hetero-aliphatic group, an aromatic group, and a heterocyclic group, provided that R.sup.1 and R.sup.2 may together form a divalent radical selected from the group consisting of an aliphatic radical and hetero-aliphatic group; PA0 each R.sup.3 is independently selected from the group consisting of an aliphatic group, a hetero-aliphatic group, an aromatic group, and a heterocyclic group; PA0 R.sup.4 is selected from the group consisting of an aliphatic group, a hetero-aliphatic group, an aromatic group, and a heterocyclic group; and PA0 n is an integer from 0 to 5. Also provided are polymerizable compositions containing such compounds and a method of coating a substrate which uses such polymerizable compositions.
