Abstract: A process for producing copolymers from monoethylenically unsaturated monomers containing acid groups and from N-vinyl lactames and possibly from other monoethylenically unsaturated monomers by copolymerising the monomers in the presence of radical-forming polymerisation initiators in the manner of solution polymerisation in water at a pH of at least 6. An alkaline metal or earth metal base or a mixture thereof is used to adjust the pH of the aqueous reaction solution.

Abstract: A photosensitive recording element which is suitable for the production of printing plates or resist images, possesses a photopolymerizable recording layer which is applied to a dimensionally stable base, can be developed in an aqueous alkaline medium and contains, as a polymeric binder, one or more film-forming copolymers which are insoluble in water but soluble or dispersible in aqueous alkaline solutions and consist of from 10 to 50% by weight of one or more hydroxyalkyl (meth)acrylates, from 8 to 30% by weight of acrylic acid and/or methacrylic acid and from 30 to 80% by weight of one or more alkyl (meth)acrylates, some of the carboxyl groups of the copolymer being esterified by reaction with glycidyl (meth)acrylate.
