Photopolymerizable material for the preparation of stable polymeric images, is provided which is characterized in that it contains, on a carrier, at least one layer composed of 1. ethylenically unsaturated monomers which are soluble in water or water-alcohol mixtures and which contain one or more terminal double bonds and at least one polar atom grouping with a lone electron pair, 2. a photoinitiator which forms together with an electron donor a photo-redox pair, especially a diazine compound which forms a photo-redox pair with the ethylenically unsaturated monomer (1) or the binder (3a), or with both of them, 3. as a matrix for the monomer (1), a swellable reaction product of at least one A. macromolecular binder which is soluble in water or water-alcohol mixtures and which has at least one polar atom grouping containing a lone electron pair, with B. a hardener, the hardener being different from the monomers of the component (1), and optionally 4. a chemically inert macromolecular compound which does not react with the binder (3a) or the hardener (3b). The polymerizable material is useful for recording information, in particular for the preparation of stable polymeric images. The hardened binder (matrix) in which the photo-polymer is embedded imparts to the image a good mechanical strength and a good adhesion to the carrier, so that the polymeric images can be used e.g. as printing plates.
