Silver halide photographic material

Claim 1

A negative-working type silver halide photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer containing a hydrazine derivative, wherein said silver halide emulsion comprises monodispersed silver halide grains comprising 50 mol% or more of silver chloride, and said hydrazine derivative is a compound represented by formula (I): ##STR40## wherein R 1 represents an aliphatic or an aromatic group; R 2 represents a hydrogen atom, alkyl group, aryl group, alkoxy group, aryloxy group, amino group or hydrozino group; G 1 represents ##STR41## thiocarbonyl group or iminomethylene group; and A 1 and A 2 each represents a hydrogen atom or one of A 1 and A 2 represents a hydrogen atom and the other represents a substituted or unsubstituted alkylsulfonyl group, substituted or unsubstituted arylsulfonyl group or substituted or unsubstituted acryl group, wherein said emulsion layer or another hydrophilic colloidal layer provided on the support contains at least one redox compound capable of releasing a development inhibitor upon oxidation, said redox compound is represented by formula (II-1), (II-2) or (II-3): ##STR42## wherein R 11 represents an aliphatic group of aromatic group; G 11 represents ##STR43## G 12 represents a mere bond, --O--, --S-- or ##STR44## in which R 12 represents a hydrogen atom or R 11 ); A 11 and A 12 each represents a hydrogen atom, alkylsulfonyl group, arylsulfonyl group or acryl group, all of which may be substituted; at least one of A 11 and A 12 in formula (II-1) is a hydrogen atom; A 13 has the same meaning as A 11 or represents ##STR45## A 14 represents a nitro group, cyano group, carboxyl group, sulfo group or --G 11 --G 12 --R 11 ; Time represents a divalent linking group; t represents an integer 0 or 1; and PUG represents a development inhibitor.
