ABSTRACT:
A multi-layer element contains a photosensitive layer composed of a mixture of an elastomeric polymer as a binder, a photopolymerizable monomer and a photopolymerization initiator, the photosensitive layer being bonded to a polyester base via an adhesive layer. The adhesive layer is composed of a reaction product, which is insoluble in the process solvents, of a hardenable cellulose ether and a polyisocyanate. The multi-layer element is particularly suitable for the production of printing plates and relief plates, and can be produced by applying a layer of an adhesive, which contains the hardenable cellulose ether and the polyisocyanate, to the polyester base, baking the adhesive to form the insoluble adhesive layer, and applying the photosensitive layer.
