ABSTRACT:
A laminate suitable for the production of printing plates and relief plates, and possessing a photosensitive layer, which is soluble in water or in an aqueous solution, and contains a hydrophilic polymeric binder, applied to a base, contains, between the base and the photosensitive layer, an intermediate layer which consists of a mixture of a polymeric binder which is compatible with the polymeric binder of the photosensitive layer and contains at least 30% by weight of a reaction product of a polyvinyl alcohol with acrylic anhydride and/or methacrylic anhydride, with at least one monomer which is compatible therewith and selected from the group consisting of the hydroxyalkyl acrylates and methacrylates and the diacrylates and dimethacrylates containing urethane groups. After application to the base, the intermediate layer is cured at 110.degree.-220.degree. C. before the photosensitive layer is applied.
