    Abstract: A radiation-sensitive mixture consists of a polymeric binder which is insoluble in water but soluble in aqueous alkaline solutions, and of an organic compound whose solubility in an aqueous alkaline developer is increased by the action of an acid and which contains both one or more acid-cleavable groups and a group which forms a strong acid under the action of radiation. The radiation-sensitive mixture is suitable for use in photosensitive coating materials for the production of relief patterns and relief images.

    Abstract: The invention relates to a radiation-sensitive mixture essentially comprising (a) a water-insoluble binder or binder mixture, and (b) a compound which forms a strong acid on irradiation, where component (a) is a phenolic resin all or some of whose phenolic hydroxyl groups have been replaced by groups (IA) or (IB) in which R , R and R are alkyl radicals, or R together with R forms a ring, and X is CH2, O, S, SO2 or NR . This radiation-sensitive mixture is suitable for the production of relief structures.
