Abstract of the Disclosure A positive-working, radiation-sensitive mixture containing a) a compound which generates a strong acid under the action of actinic radiation, b) a compound having at least one C-O-C or C-O-Si bond cleavable by acid and c) a polymeric binder which is insoluble in water and soluble or at least swellable in aqueous alkaline solutions, wherein the compound (a) is a 1,3,5- or 1,2,4-tri- hydroxybenzene or a 1,2,3-, 1,3,5- or 1,2,4-trihydroxy- benzene substituted on the aromatic ring by a radical R'; or a polymer containing a dihydroxy-phenoxy radical or a polymer containing a trihydxoxy phenylene radical; wherein the hydroxybenzene or hydroxy-containing polymer is partially or fully esterified with sulfonic acids of the formula R-SO3H, is distinguished by high resolution and high sensitivity over a wide spectral range. It also shows high thermal stability and does not form any corrosive photolysis products on exposure. A radiation- sensitive recording material which has been produced with mixture is suitable for the production of photoresists, electronic components, printing plates, or for chemical milling.
