Abstract
A photopolymerizable composition comprising: (a) 100 parts by weight of a compound having at least one ethylenically unsaturated group, (b) 0 to 400 parts by weight of a thermoplastic organic polymer and (c) 0.01 to 20 parts by weight of a photoinitiator, characterized in that an acridine compound of the following general formula (I) is used as the photoinitiator: ##STR1## wherein R represents an alkylene, oxadialkylene or thiodialkylene group having 2 to 20 carbon atoms, and a photopolymerizable element comprising a layer of the photopolymerizable composition formed on a support.
