摘要

A hydrazine compound represented by the following formula (I):Ar1-NH-NH-G1-R1(I)wherein Ar1 represents an aromatic group; G1 represents a carbonyl group, a sulfonyl group, a sulfoxy group, a phosphoryl group, an oxalyl group or an iminomethylene group; R1 represents a hydrogen atom or a block group; and at least one of Ar1 and R1 has a group represented by the following formula (II): wherein * represents a bond for connecting directly or through a liking group to Ar1 or R1; Z represents a nonmetallic atom group capable of forming a 5- or 6-membered unsaturated heterocyclic ring having a conjugated positive charge; and X- represents -O-, -S- or -N--R2, wherein R2 represents an alkyl group, an alkenyl group, an alkynyl group, an aryl group or a heterocyclic group. Also disclosed is a silver halide photographic light-sensitive material containing the hydrazine compound.
