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 N-vinylamides, from 8 to 30% by weight of acrylic acid and/or methacrylic acid and from 30 to 80% by weight of one or more hydrophobic comonomers which, as such, form homopolymers which are insoluble in water and aqueous alkaline solutions, some of the carboxyl groups of the copolymer being esterified by reaction with glycidyl (meth)acrylate.
