    摘要: Compounds suitable for use as acutance, antihalation and filter dyes in silver halide imaging materials having a nucleus represented by a compound comprising a nucleus represented by one of the following general formulae (I) and (II):


    in which;
       A and B independently represent those non-metallic atoms necessary to complete a neutral heterocyclic ring in which at least one ring atom is nitrogen,
       R represents hydrogen or an alkyl group, and
       Y represents a divalent aliphatic linking group.
