Photo-crosslinkable, novel polymers with side tricyclic imidyl groups, for example those of the formula ##STR1## are described. The novel photo-crosslinkable polymers are suitable for photo-mechanical applications, for example for the production of printing plates for the offset printing process and especially as photo-resists. They have high UV absorption and ensure a high rate of crosslinking even without the addition of photosensitizers.
                            描述了具有侧
三环咪唑基团的光交联新型聚合物,例如公式##STR1##所示的聚合物。这些新型光交联聚合物适用于光机械应用,例如用于生产胶印工艺的印刷版,特别是作为光阻剂。它们具有高的紫外吸收率,即使没有添加光敏剂也能确保高的交联速率。
