| 摘要 |
A mixture which is crosslinkable by photopolymerisation, is soluble or dispersible in aqueous media and is based on hydroxyl- and/or amido-containing polymers as binders, photopolymerisable monomers which are compatible therewith and photopolymerisation initiators and which contains, based on its total amount, from 0.1 to 10% by weight of an aldehyde of the formula I
<IMAGE>
in which R is a hydrogen atom, a hydroxyl group or a C1-C6-alkyl, C1-C6-alkoxy, C6-C10-aryl or C6-C10-aryloxy radical,
can be used in multilayer photosensitive recording materials which can be developed using aqueous media and contain at least one layer of a mixture of this type.
