Abstract
A radiation-sensitive compound has the general formula ##STR1## wherein A represents the ring members required to complete a 5- or 6-membered heterocyclic ring which may optionally be fused to an optionally substituted aromatic nucleus, PA1 B represents H, acyl, aroyl, heterocyclyl carbonyl or ##STR2## R represents an optionally substituted alkyl group, E and G, which may be the same or different, each represents H or CH.sub.p X.sub.3-p, PA1 J and K, which may be the same or different, each represents an aryl or heterocyclic group, which may optionally include a substituent additional to E or G, PA1 X represents Cl or Br, and m,n and p, which may be the same or different, each represents an integer equal to 0, 1 or 2. The compound can be used to form radiation sensitive compositions for the production of radiation sensitive plates in lithographic printing plate manufacture.
