Abstract: Photosensitive coating materials comprising polymers containing o-nitrocarbinol ester groups, particularly of polymers and copolymers of o-nitrocarbinol esters of ethylenically unsaturated carboxylic acids, which as a result of exposure become soluble in an alkaline solvent used as developer in which they were not soluble prior to exposure. Such materials are used in particular for coating lithographic printing plates and as photoresists.
