Abstract: The invention relates to a radiation-sensitive mixture and to a process for the formation of relief patterns. The radiation-sensitive mixture contains (a) a polymeric binder which is insoluble in water and soluble in aqueous-alkaline solutions, and (b) an organic compound whose solubility in an aqueous-alkaline developer is increased by the action of acid and which contains at least one grouping cleavable by acid and additionally one grouping which forms a strong acid under the action of radiation, the polymeric binder (a) containing 5 to 35 mol% of copolymerised or co-condensed monomer units having acid-sensitive groupings, or the acid-sensitive groupings having been introduced by a polymer-analogous reaction. It is suitable for the formation of relief patterns.

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 photosensitive, ethylenically unsaturated, copolymerisable sulphonium salts and a method for their production. The sulphonium salts according to the invention have the general formula [(R)a(R )b(R )cS] A where R, R and R are organic radicals, at least one of which contains an ethylenically unsaturated group, a+b+c = 3 and A is an acid anion. The sulphonium salts according to the invention are suitable, inter alia, for cationically curable mixtures.
