ABSTRACT:
A photopolymerizable composition comprises: (1) a free radical polymerizable material, such as ethylenically unsaturated monomers and (2) a photoinitiator system of (a) a compound having an oxirane group in an alpha,beta-position to a carbonyl group, typical of which is 1-benzoyl-2-phenylethylene oxide and (b) a tertiary amine or other electron donor.
