Abstract

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.
