Abstract

Compounds added to initiate photopolymerization of monomers to produce polymeric coatings include compounds of the formula ##STR1## wherein Ar is phenyl or naphthyl, PA0 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, PA0 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, PA0 R.sub.1 is hydrogen or methyl, PA0 n is a number with a value from about 2 to about 5, and PA0 n+m is a number with a value from about 3 to about 6.
