Abstract
Abstract Compounds added to initiate photopolymerization of monomers to produce polymeric coatings include compounds of the formula ##STR1## wherein Ar is phenyl or naphthyl, R is hydrogen, alkyl with 1-4 carbon atoms, alkoxy with 1-4 carbon atoms, halogen, dialkylamino with 1-4 carbon atoms in each alkyl group, carboxyl, or alkoxycarbonyl with 1-4 carbon atoms in the alkoxy group, X is alkyl having 3 to 6 carbon atoms or alkyl having 6 to 72 carbon atoms interrupted by at least one member selected from the group consisting of ##STR2## and the precursor of X being a polyol having 3 to 6 hydroxyls and having a hydroxyl number of from 100 to 1850, R 1 is hydrogen or methyl, n is a number with a value from about 2 to about 5, and n+m is a number with a value from about 3 to about 6.
