ABSTRACT:
Photo-sensitive film-forming soluble polymeric materials containing one or two polymers which can be insolubilized photochemically are disclosed. These polymeric materials contain in the same or different polymers (A) components which are reactive with moieties obtained by the photochemical decomposition of azidosulphonyl groups, e.g., a hydroxyl radical, pyridine, a phenyl radical, or a lactam radical; and (B) azidosulphonyl groups. The photo-sensitive material is insolubilized by exposure to actinic light. The material is useful in the production of photographic resists, printing plates for lithography, and the like.
