Abstract

Multilayer, photosensitive recording materials which can be developed with aqueous media contain one or more layers of a mixture which is crosslinkable by photopolymerization, soluble or dispersible in aqueous media and based on polymer containing hydroxyl and/or amide groups, as binders, compatible photopolymerizable monomers and photopolymerization initiators, which mixture contains from 0.1 to 10% by weight, based on its total amount, of an aldehyde of the general formula I ##STR1## where R is hydrogen, hydroxyl, C.sub.1 -C.sub.6 -alkyl, C.sub.1 -C.sub.6 -alkoxy, C.sub.6 -C.sub.10 -aryl or C.sub.6 -C.sub.10 -aryloxy.
