    • A photosensitive resin composition comprising (I) a copolymer containing (A) 10 to 95 mol % of a conjugated diolefinic hydrocarbon, (B) 5 to 90 mol % of an .alpha.,.beta.-ethylenically unsaturated carboxylic acid and (C) 0 to 85 mol % of a monoolefinically unsaturated compound, (II) a photosensitizer and/or a photosensitive crosslinking agent, and, if necessary, (III) a photopolymerizable unsaturated monomer. Said copolymer may have been reacted with an inorganic alkali, an alkali salt or an amine compound in a proportion of 0.05 to 1.0 equivalent per equivalent of the carboxyl group of the .alpha.,.beta.-ethylenically unsaturated carboxylic acid in said copolymer. This photosensitive resin composition is excellent in storage stability, quick in photosetting upon exposure to actinic light rays including ultraviolet rays, that is, high in sensitivity, capable of development with water or a dilute aqueous alkaline solution and possesses satisfactory rubber elasticity, and a printing plate formed from the composition is excellent in water resistance though the composition is developable with an aqueous developing solution, so that the composition can be used for a flexographic printing plate, to which an aqueous flexographic printing ink can be applied. Said composition can also be used for a pohote-resist which is high in sensitivity, developable with water or a dilute alkaline solution and excellent in resolving power.
    • 一种感光性树脂组合物,其包含(I)含有(A)10〜95摩尔%的共轭二烯烃的共聚物,(B)5〜90摩尔%的α,β-烯键式不饱和羧酸和(C)0〜85 摩尔%的单烯属不饱和化合物,(II)光敏剂和/或感光交联剂,如果需要,(III)可光聚合的不饱和单体。 所述共聚物可以与无机碱,碱金属盐或胺化合物以相当于所述共聚物中α,β-烯键式不饱和羧酸的羧基的0.05至1.0当量的比例反应。 该感光性树脂组合物的保存稳定性优异,曝光于包含紫外线的光化射线即使感光度高,能够用水或稀碱水溶液显影并且具有令人满意的橡胶弹性, 由组合物形成的板材具有优异的耐水性,尽管组合物可用水性显影液显影,使得该组合物可用于柔性版印刷版,可将柔性版印刷油墨用于该柔版印刷油墨。 所述组合物也可用于灵敏度高,可用水或稀碱性溶液显影并具有优异的分辨能力的柔软抗蚀剂。
