    Abstract: Photopolymerisable recording material with at least one photopolymerisable, olefinically unsaturated organic cpd. (I), opt. a polymeric binder (II), at least one photopolymerisation initiator (III), a colour forming system (IV) which on irradiation with actinic radiation causes an increase in the colour intensity of the recording material, a sensitizer (V) and opt. further additives and/or assistants, the (IV) comprising (a) least one colourless or practically colourless organic cpd. which is oxidisable to a coloured cpd., and (b) a photooxidation agent for (a) comprising an organic salt with an opt. substd. heteroaromatic system including at least one grouping of formula (A) in which R = opt. substd. alkenyl, alkynyl, hetaryl, alkenylcarbonyl, alkynylcarbonyl, alkoxycarbonyl, carbamoyl, alkylsulphonyl, arylsulphonylaminosulphinyl, substd. cycloalkyl or opt. substd. hetaryl cation, with the proviso that the long wave absorption max. of the salt is below 400 nm.
