ABSTRACT:
A photopolymerizable composition is described, which comprises a polymerizable compound containing at least one ethylenically unsaturated double bond and a photopolymerization initiator wherein the photopolymerization initiator is a combination of a 3-keto-substituted cumarin compound and an active halogeno compound. This composition can be easily cured by irradiation with radiation and, therefore, is very useful in the preparation of light-sensitive materials.
