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.
本发明揭示了一种含有一种或两种可通过光
化学方法使其不溶化的聚合物的光敏感感的可形成溶解性聚合物材料。这些聚合物材料在相同或不同的聚合物中包含(A)与通过偶氮磺酰基团的光
化学分解获得的官能团反应的组分,例如羟基自由基、
吡啶、苯基自由基或内酰基自由基;以及(B)偶氮磺酰基团。通过接触到紫外光,这种光敏感材料可以使其不溶化。该材料可用于生产光刻胶、平版印刷板等。
