<p>A light-sensitive coating composition and a lightsensitive photomechanical structure, such as a printing plate or a photoresist is produced by coating a suitable planar substrate with a condensation product of an organic isocyanate and a polymeric resin having functional groups reactive with the isocyanate, such as phenol-formaldehyde resin, and a light-sensitive diazo compound, such as the esters and amides of quinone and naphthoquinone diazides, the coating being softenable by exposure to light and subsequent treatment with a conventional liquid printing plate developer, such as an aqueous alkaline solution and/or an organic solvent.</p> |
