ABSTRACT:
This invention relates to an improvement in a radiation-sensitive mixture containing (a) a compound which forms an acid under the influence of actinic radiation and (b) a compound which has at least one acid-cleavable bond and the solubility of which in a liquid developer is increased by the action of an acid, the improvement that the compound which is capable of being cleft by an acid contains at least one N-acyliminocarbonate group as the acid-cleavable group. The invention also relates to a process for producing relief images using the radiation-sensitive mixture.
