ABSTRACT:
A photopolymerizable composition comprising photopolymerizable ethylenically unsaturated compounds and, as the photoinitiator, a glyoxylamide having the formula: ##STR1## wherein R and R.sup.1 are individually selected hydrogen or hydrocarbon of from 1 to 10 carbon atoms; R.sup.2 is a heterocyclic radical, aryl of from 6 to 14 carbon atoms or mono-, di- or polysubstituted phenyl with substituents selected from the group consisting of alkyl, alkoxy, aryloxy, alkylthio, arylthio and halogen; R.sup.3 is phenyl or--CH.sub.2).sub.z
Where z is an integer from 2 to 6;
X is zero, oxygen, sulfur, --NH--, phosphorus or silicon; and n is an integer from 2 to 4. The composition cures upon exposure to actinic radiation.
