Beschreibung
Zusammenfassung:A photosensitive coating composition useful for the production of printing plates and for forming photoresists for metal plating and etching of metal, ceramic or the like comprising a light-sensitive diazo compound as photosensitizer, a polyvinyl ether, and preferably, an alkali soluble resinous material such as a novolak resin. The addition of the polyvinyl ether provides a coating of improved flexibility, electrical and chemical resistance, and thickness characteristics.
