A novel silver halide photographic material is provided, comprising at least one methine compound having a methine dye and hydrazine covalently bonded to each other, two nitrogen atoms in said hydrazine being substituted by four substituents. In a preferred embodiment, the methine compound is represented by formula (I): <IMAGE> (I) wherein MET represents an atomic group; Q represents a divalent bonding group consisting of atoms or atomic group containing at least one of carbon atom, nitrogen atom, sulfur atom and oxygen atom; Hy represents an atomic group having a hydrazine structure represented by formula (II); k1 represents 0 or an integer 1 to 4; and k2 represents 0 or 1, and k3 represents an integer 1 to 4. <IMAGE> (II) wherein R1, R2, R3 and R4 each represents an alkyl group, an aryl group or a heterocyclic group, with the proviso that Hy is substituted by at least one -(Q)k2-(MET)k1. A novel methine compound is also provided represented by the general formula (I).
