Flexographic printing element which can be digitally imaged and has a polar, ultra-thin barrier layer

摘要

The invention relates to flexographic printing elements which can be digitally imaged, for producing flexographic printing plates which can be developed using hydrocarbon-including washout products, and which have a polar, ultra-thin oxygen-blocking barrier layer between the photopolymerizable layer and the layer that can be digitally imprinted. The invention also relates to a method for producing flexographic printing plates using said flexographic printing elements which can be digitally imaged, by imaging, exposure, washout, drying and post-treatment, the washout being done by means of hydrocarbon-including washout products.
