    摘要: A negative-working radiation-sensitive mixture containinga) a compound which generates a strong acid under the action of actinic radiation,b) a compound having at least two groups crosslinkable by means of acid andc) a polymeric binder which is insoluble in water and soluble or at least swellable in aqueous alkaline solutions,wherein the compound (a) comprises a di-, tri- or tetra-hydroxybenzene which may be further substituted, or a polymer containing a di-, tri-, or tetra- hydroxy phenyl radical, is esterified with respectively 2, 3 or 4 sulfonic acids of the formula R--SO.sub.3 H, and 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 produced with this mixture is suitable for the production of photoresists, electronic components, printing plates or for chemical milling.
