Abstract
An imagable composition, for example a coating on a lithographic printing plate, comprises a carboxylic acid derivative of a cellulosic polymer and a diazide moiety, and may be imaged in various ways, including by ultra-violet radiation, by infra-red radiation and by heat. The presence of the cellulosic polymer can act to enhance resistance to certain organic liquids and/or to increase operating speed.
