ABSTRACT:
A radiation-sensitive compound, which comprises a polymer including a plurality of azide-substituted aromatic ester groups and a plurality of carboxylic or sulphonic acid groups capable of imparting to the compound solubility in aqueous or alkaline medium. After image-wise exposure, the compound can be developed using an aqueous or alkaline developer. The compound is useful in the production of radiation sensitive plates for the manufacture of lithographic printing plates which can be baked to improve printing life.
