    • The invention relates to a developer for irradiated, radiation-sensitive recording materials, in particular for the production of offset printing plates, which contains water, a compound which is alkaline in aqueous solution and a copolymer which acts as an emulsifier and has units of (I) a hydrophobic vinyl compound which has at least one optionally substituted mono- or bicyclic (C.sub.6 -C.sub.14)aryl radical and (II) a hydrophilic, ethylenically unsaturated carboxylic acid. Some of the carboxyl groups of the copolymer are esterified with reaction products of (A) (C.sub.1 -C.sub.30)alkanols, (C.sub.8 -C.sub.25)alkanoic acids, (C.sub.1 -C.sub.12)-alkylphenols or di(C.sub.1 -C.sub.20)alkylamines with (B) (C.sub.2 -C.sub.4)-alkylene oxides or tetrahydrofuran, the molar ratio (A):(B) being in the range from 1:2 to 1:50. If it is intended to develop recording materials having a negative-working layer, the developer additionally contains a water-miscible organic solvent and a surface-active compound. The developer has a low initial viscosity, which increases only slowly with increasing contamination with layer components. Furthermore it shows only a particularly low tendency to foam.

    • A photosensitive recording material is described which has a layer base, a negative-working photosensitive layer containing a diazonium salt and a water-insoluble polymeric binder which is soluble or swellable in aqueous alkaline solutions, and a discontinuous top layer which forms a rough surface and which is composed of particles of a water-insoluble polymer which is dispersible in water in the presence of anionic or anionic/nonionic dispersants and which has a content of free acid groups or acid groups neutralized by salt formation of less than 0.8 mmol/g, the mean height of the particles being 2 to 6 .mu.m, the maximum height less than 10 .mu.m, the mean horizontal diameter less than 40 .mu.m, the maximum diameter less than 80 .mu.m and the number of particles being 100 to 10,000 per cm.sup.2. The material is suitable for the production of planographic printing plates and requires only short vacuum times in a vacuum-operated copying frame. The material can be developed without residue after exposure, the rough surface remaining intact at the image areas.
