CESSIBLE FLEXOGRAPHIC PRINTING PLATE

摘要

This invention relates to a method to facilitate removal of a negative or positive image-bearing film from an aqueous or semi-aqueous processible flexographic printing element which comprises using a hydroxyalkyl cellulose release layer interposed between the image-bearing film and a photosensitive layer, wherein the alkyl group has from one to five carbon atoms. This invention also concerns an aqueous or semi-aqueous processible flexographic photosensitive element containing this release layer and to processes for making printing reliefs from such elements.
