Abstract:
A photopolymerizable recording material which comprises a support layer and a photopolymerizable layer sensitive to ultraviolet and near- ultraviolet light, said photopolymerizable layer comprisinga) a polymeric binder,b) a compound which can be polymerized by free radicals and has at least one terminal ethylenic double bond,c) a photoinitiator combination which is sufficient to start polymerization under ultraviolet and near-ultraviolet light consisting essentially of1) a N-heterocyclic compound effective as a photoinitiator selected from the group consisting of acridines, phenazines, quinoxalines and quinolines,2) a thioxanthone derivative of the formula I ##STR4## and 3) a dialkylamino compound of the formula II or III ##STR5## in which R.sup.1, R.sup.2, R.sup.3, and R.sup.4 are independently selected from the group consisting of halogen, alkyl, alkoxy, carboxyl, alkoxycarbonyl and aryloxycarbonyl,R.sup.5, R.sup.6, R.sup.9 and R.sup.10 which may be the same or different, denote alkyl groups,R.sup.7 is an alkyl or alkoxyalkyl group, andR.sup.8 denotes an alkylene group.
