Beschreibung
Zusammenfassung:	1. Positive-working, light-sensitive mixture, the solubility of which in an aqueous-alkaline solution is increased on exposure and which contains a light-sensitive compound or a light-sensitive combination of compounds and, as the binder, a polyvinyl phenol which is insoluble in water, but soluble in aqueous-alkaline solutions, wherein the polyvinyl phenol is halogenated and wherein said mixture contains, as the light-sensitive combination, a composition comprising : a) a compound which eliminates an acid on exposure and b) a compound which containes at least one acid-cleavable C-O-C-bond.
