Positive radiation-sensitive mixture and recording material produced therefrom

摘要

A positive radiation-sensitive mixture is disclosed comprising a compound which forms an acid under the action of high-energy radiation and an acid-cleavable compound, wherein the compound which forms an acid contains aromatically bound chlorine or bromine and has a pKa value of less than about 12 or is a derivative of a compound having such a pKa value. The mixture and the recording material produced therefrom have a relatively high-sensitivity and improved resolution and, in addition, exhibit no scumming after development.
