在可光聚合层中具有三元共聚物粘合剂的光敏光聚合记录元件

Photosensitive photopolymerizable recording element having a terpolymer binder in the photopolymerizable layer
摘要：
A photosensitive recording element which is suitable for the production of printing plates or resist images, possesses a photopolymerizable recording layer which is applied to a dimensionally stable base, can be developed in an aqueous alkaline medium and contains, as a polymeric binder, one or more film-forming copolymers which are insoluble in water but soluble or dispersible in aqueous alkaline solutions and consist of from 10 to 50% by weight of one or more hydroxyalkyl (meth)acrylates, from 8 to 30% by weight of acrylic acid and/or methacrylic acid and from 30 to 80% by weight of one or more alkyl (meth)acrylates, some of the carboxyl groups of the copolymer being esterified by reaction with glycidyl (meth)acrylate.
摘要（中）：

适用于生产印版或抗蚀剂图像的光敏记录元件具有应用于尺寸稳定的基底的可光聚合记录层，可在含水碱性介质中显影并含有作为聚合物粘合剂的一种或多种 不溶于水但可溶于或分散于碱性水溶液中的成膜共聚物，其组成为10至50重量％的一种或多种（甲基）丙烯酸羟烷基酯，8至30重量％的丙烯酸和/或 甲基丙烯酸和30〜80重量％的一种或多种（甲基）丙烯酸烷基酯，共聚物的一些羧基通过与（甲基）丙烯酸缩水甘油酯反应而酯化。
