ABSTRACT:
A silver halide photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer, wherein at least one of the silver halide emulsion layer and a hydrophilic colloid layer(s) adjacent thereto contains at least one hydrazine compound represented by the following general formula (I) and at least one compound selected from the group consisting of compounds represented by the following general formula (II) and (III): ##STR1## wherein R.sub.1 represents an aliphatic or aromatic group which has a substituent having a moiety of --O(CH.sub.2 CH.sub.2 O).sub.n --, --O--(CH.sub.2 CH(CH.sub.3)O).sub.n -- or --O--(CH.sub.2 CH(OH)CH.sub.2 O).sub.n -- (wherein n is an integer of not smaller than 3) as part of a substituent or having a moiety of a quaternary ammonium cation as part of a substituent group, G.sub.1 represents a bivalent bonding group consisting of at least one of --CO--, --COCO--, --CS--, --C(.dbd.NG.sub.2 R.sub.2)--, --SO--, --SO.sub.2 -- or --P(O)(G.sub.2 R.sub.2)--; G.sub.2 represents a single bond, --O--, --S-- or --N(R.sub.2)--; R.sub.2 represents an aliphatic group, an aromatic group or a hydrogen atom, and when there are two or more R.sub.2 groups, they may be the same or different; and one of A.sub.1 and A.sub.2 is a hydrogen atom, and the other is a hydrogen atom, an acyl group or an alkyl- or arylsulfonyl group, when R.sub.1 contains said quaternary ammonium cation, the compound further has a counter anion or has an anion group at R.sub.1 to form an inner salt; ##STR2## wherein Y represents a group which is adsorbed to silver halide; X represents a bivalent bonding group comprising an atom or atoms selected from hydrogen, carbon, nitrogen, oxygen and sulfur atoms; A represents a bivalent bonding group; B represents an amino group which may be substituted, an ammonium group or a nitrogen-containing heterocyclic ring; m represents 1, 2 or 3; and n represents 0 or 1; ##STR3## wherein R.sub.1 and R.sub.2 each represents a hydrogen atom or an aliphatic group, or R.sub.1 and R.sub.2 may be combined together to form a ring; R.sub.3 represents a bivalent aliphatic group; X represents a bivalent heterocyclic ring having at least one of hetero-atoms of a nitrogen, oxygen or sulfur atoms; n represents 0 or 1; and M represents a hydrogen atom, an alkali metal atom, an alkaline earth metal atom, a quaternary ammonium, a quaternary phosphonium or an amidino group; x is 1 when M represents a monovalent atom or group and x is 1/2 when M represents a divalent atom; said compound may be in the form of an addition salt.
