Abstract
A photosensitive recording material with a layer base and a photosensitive layer, which essentially contains a diazonium salt polycondensation product, a polymeric binder which is insoluble in water and soluble in organic solvents and soluble or at least swellable in aqueous alkaline solutions, a polymerization initiator which forms free radicals when exposed to actinic radiation and a polymerizable ethylenically unsaturated compound containing at least one unsaturated group and having a boiling point at normal pressure of over 100.degree. C., wherein the recording material contains, between the photosensitive layer and the layer base, a photosensitive intermediate layer which essentially contains a diazonium salt polycondensation product and a polymeric binder which is insoluble in water and soluble in organic solvents and soluble or at least swellable in aqueous alkaline solutions.
