A radiation-sensitive compound has the general formula <CHEM> 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, B represents H, acyl, aroyl, heterocyclyl carbonyl or <CHEM> R represents an optionally substituted alkyl group, E and G, which may be the same or different, each represents H or CHpX3-p, 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, 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. |
