ABSTRACT OF THE DISCLOSURES: Disclosed are polymers which have been modified by a polymer-analogous reaction, are in the acid form or in the form of their salts, and 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 copolymer by a polymer-analogous reaction and are of the general formula I Image ( 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. These polymers are useful for the production of dimensionally stable materials, printing plates, relief plates and photoresists which have a long shelf life and can be crosslinked by photopolymerization, and of thermally stable and non-tacky photocrosslinked materials, printing forms, relief forms and photoresists which have a high tensile strength.
