ABSTRACT:
An azomethine dye represented by the following general formula (I) ##STR1## wherein A represents a dye residue formed by removing one hydrogen atom from an indophenol or indoaniline dye; L represents a divalent bonding group; and Z represents a non-metallic atomic group required for forming a three-membered to eight-membered heterocyclic ring together with N, provided that a carbonyl group is not directly bonded to N in the heterocyclic ring. Also disclosed is a silver halide photographic material having an emulsion layer with a covering power of at least 60, and wherein the silver halide photographic material contains at least one member of the dyes of general formula (I) in such an amount that an increase in transmission density in unexposed areas caused by the incorporation of the dye therein after development is not more than 0.06.
