Abstract

A radiation sensitive material suitable for the production of radiation sensitive plates for lithographic printing plate manufacture comprises a polymer having appendent azide-substituted aromatic ester groups and sulphonyl urethane groups. The radiation sensitive compound is produced by a process in which some hydroxyl and/or epoxide groups of a polymer are reacted with an azide substituted carboxylic acid or ester forming derivative thereof, and some hydroxyl groups are reacted with a sulphonyl isocyanate.
