A positive-working radiation-sensitive mixture essentially consists of (a1) at least one water-insoluble, organic polymeric binder which contains acid-labile groups and becomes soluble in aqueous alkaline solutions as a result of the action of acid, or (a2.1) a polymeric binder which is insoluble in water and soluble in aqueous alkaline solutions and (a2.2) a low molecular weight organic compound whose solubility and aqueous alkaline developer is increased as a result of the action of acid, and (b) at least one organic compound which produces an acid under the action of actinic radiation, and, if required, (c) one or more further organic compounds which differ from (b), at least one of the components (a1), (a2.1), (a2.2), (b) and (c) containing a bonded group of the general formula (I) -O(-)N(+)R4, or component (c) being of the formula (II) <IMAGE> (II) The radiation-sensitive mixture is suitable for the production of relief structures.
