Abstract

Digital imageable flexographic printing elements for producing flexographic printing plates, which are developable using hydrocarbon-comprising washout media and which, between the photopolymerizable layer and the digital imageable layer, have a polar, ultrathin, oxygen-blocking barrier layer. Methods for producing flexographic printing plates using such digital imageable flexographic printing elements, by imaging, exposing, washing out, drying, and post-treating, the washout being formed by means of hydrocarbon-comprising washout media.
