摘要:
The invention relates to a radiation-sensitive mixture essentially consisting of(a) a water-insoluble binder or binder mixture which is soluble in aqueous alkaline solutions,(b) a compound which upon irradiation forms a strong acid and(c) one or more organic compounds which inhibit the solubility of (a) in aqueous alkaline solutions,where the organic compound (c) is a malonic acid ester.This radiation-sensitive mixture may be used to prepare photoresists.
