Abstract
A radiation-sensitive recording material comprising a support and first and second radiation-sensitive layers is disclosed. The first radiation-sensitive layer comprises a 1,2-quinone diazide as the radiation-sensitive compound and the second radiation-sensitive layer comprises (a) a compound which forms a strong acid under the action of actinic radiation, (b) a compound which has at least one acid-cleavable C-O-C bond and (c) a polymeric binder. The recording material has an improved storage stability as compared with materials which comprise only radiation-sensitive layers based on acid-cleavable compounds.
