    Abstract: Non-tacky, smooth, structureless surfaces of photopolymer relief printing plates for flexographic printing, whose relief layers are prepared in a conventional manner by exposing the photopolymerizable relief-forming layers of flexographic printing plates imagewise to actinic light and washing out the unpolymerized, unexposed areas with a suitable solvent, are produced by a process in which the flexographic printing plates are after-treated with a liquid medium which contains elemental bromine or is capable of forming elemental bromine, and then washed with a neutralization bath, one or more paraffinsulfonates, fatty alcohol ethersulfates or alkyl phosphates or a cationic or anionic surfactant possessing one or more perfluorinated carbon chains being employed in the bromine-containing, liquid medium. The relief printing plates obtained according to the invention are used for flexographic printing.

    Abstract: Polymers which have been modified by a polymer-analogous reaction, in the acid form or in the form of their salts, consist of a copolymer of ethylene, (meth)acrylic acid and one or more compounds selected from the group consisting of vinyl esters, vinyl ethers, (meth)acrylates and (meth)acrylamides, and olefinically unsaturated side radicals which have been introduced into the said copolymer by a polymer-analogous reaction and are of the general formula I I where X is hydroxyl, amino or mercapto, Y is an ester, amide, ether or C1-C10-alkylene group and R is hydrogen or methyl.
