摘要：
Disclosed is a radiation-sensitive composition, a recording material prepared therewith, and process therefor. The invention is suitable for the production of printing plates and photoresists. The composition contains a 1,2-quinonediazide or a combination of (1) a compound which, under the action of actinic radiation, forms a strong acid, and (2) a compound which possesses at least one acid-cleavable C--O--C bond, the solubility of which in a liquid developer is increased by the action of acid and, as the binder, a polymer having lateral crosslinking groups of the formula --CH.sub.2 OR, in which R is a hydrogen atom, a lower alkyl group, acyl group or hydroxyalkyl group. After being exposed and developed, the composition can be thermally cured and results in an image stencil exhibiting a clean background.
