摘要:
A silver halide photographic material comprising at least one silver halide emulsion layer on a support, characterized in that there is contained a compound represented by the general formula ##STR1## wherein R.sup.1 and R.sup.2 each represents a hydrogen atom, aliphatic group, aromatic group or heterocyclic group, with the proviso that R.sup.1 and R.sup.2 may be connected to each other to form a ring; L represents a divalent linking group; V represents a carbonyl group, ##STR2## group, sulfonyl group, sulfoxy group, ##STR3## group (in which R.sub.0 represents an alkoxy group or aryloxy group), iminomethylene group or thiocarbonyl group; Time represents a divalent linking group; m represents an integer 0 or 1; n represents an integer 0 or 1; PUG represents a photographically useful group; and X represents an atomic group required to form a 5- or 6-membered ring with ##STR4## wherein R.sup.1, R.sup.2, V, m, n and Time are defined above; L' represents a divalent linking group; and X represents an atomic group required to form a 5- or 6-membered ring with ##STR5## and PUG represents photographically useful groups set forth in the specification.
