Abstract
Flexographic printing plates are produced by thermal development by a process in which an imagewise exposed flexographic printing element is developed by heating and removing the softened, unpolymerized parts of the relief-forming layer, the flexographic printing element used comprising an olefin/(meth)acrylate copolymer having an olefin content of from 50 to 94 mol %. The photopolymerizable flexographic printing element comprises an olefin/(meth)acrylate copolymer having a content of from 50 to 94 mol % of olefin monomers, from 6 to 50 mol % of (meth)acrylate monomers and from 0 to 5 mol % of further comonomers. This flexographic printing element is used for the production of flexographic printing plates both by thermal development and by development by means of washout compositions.
