Beschreibung
Zusammenfassung:	Positive images are produced by i) exposing a layer of a composition containing A) a film-forming organic material and B) an aromatic oxime sulphonate to a given pattern of actinic radiation, in which process said composition acquires a higher solubility in an aqueous alkaline developer in the exposed surface parts than in the unexposed surface parts, and ii) removing the exposed surface parts of said composition by treatment with an aqueous alkaline developer. The imaging process is suitable for producing printing plates and electronic circuits.
