A radiation-sensitive material is described that comprises a hydrophilic colloid layer containing a dispersed phase of at least one radiation sensitive polymer the polymer chain of which comprises units with side substituents containing oxime ester groups. Upon imagewise exposure to actinic radiation of the polymer in the exposed areas reduces the permeability of the hydrophilic colloid layer for an etchant in the absence of any ethylenically unsaturated monomer. The layer having upon imagewise exposure to radiation image-wise differentiations in permeability for an etchant can be used as etch-resist, without needing a washing away step, to modify image-wise the surface of an element e.g. to produce printed circuits or printing forms.
描述了一种辐射敏感材料,它包括一个亲水胶体层,该胶体层含有至少一种辐射敏感聚合物的分散相,该聚合物的聚合物链包括侧取代基含有肟酯基团的单元。当聚合物在受照区域受到光辐射时,亲水胶体层在没有乙烯不饱和单体的情况下对蚀刻剂的渗透性会降低。在图像上暴露于辐射时,该层对蚀刻剂的渗透性随图像的变化而变化,可用作蚀刻-抗蚀剂,无需清洗步骤,就能在图像上改变元件的表面,例如生产印刷电路或印刷品。
