A photopolymerizable printing plate has a dimensionally stable support, a photopolymerizable layer, a top layer located thereon comprising two mutually incompatible, elastomeric block copolymers, and a protective sheet. Disclosed are processes for producing such a photopolymerizable printing plate, processes for producing relief printing plates, especially flexographic printing plates, and also relief printing plates having ink cells in the relief surface.

Photopolymerizable printing plates with top layer for producing relief printing plates

A process for the production of a photosensitive recording material for producing relief printing plates is described, in which a photosensitive layer is laminated with a composite element comprising a protective cover sheet, a release layer and, if required, a further layer, wherein the surface of the uppermost layer of the composite element or the surface of the photosensitive layer is subjected to a corona treatment immediately before contact. As a result of the corona treatment, the adhesion of the applied layer is substantially increased.
