Abstract

A radiation-sensitive composition is disclosed which comprises: (a) a polymeric binder comprised of an alkenyl phenol monomer; (b) a compound which forms a strong acid under the action of actinic radiation; and (c) a compound which contains at least one acid-cleavable C-O-C bond and has a solubility in a liquid developer which is increased by the action of acid. The composition yields positive-working recording layers which are more flexible than layers comprising known novolak binders.
