ABSTRACT:
Disclosed is a process for the preparation of relief copies, comprising the steps of imagewise irradiating a radiation-sensitive copying material comprising a layer support and a radiation-sensitive layer comprising (a) a compound which upon irradiation splits off acid, and (b) a compound possessing at least one acid-cleavable C--O--C group; heating the imagewise irradiated copying material to a temperature above room temperature for a period of time sufficient to produce an increase in radiation sensitivity of the radiation-sensitive layer; and washing out the irradiated layer areas by means of a developer.
