A novel silver halide photographic material comprising at least one methine compound represented by the following general formula (I):
wherein R¹ represents -(CH₂)r-CONHSO₂-R³, -(CH₂)s-SO₂NHCO-R⁴, -(CH₂)t-CONHCO-R⁵ or -(CH₂)u-SO₂NHSO₂-R⁶ in which R³, R⁴, R⁵ and R⁶ each represents an alkyl group, alkoxy group or amino group, r, s, t and u each represents an integer 1 to 5, and R² represents has the same meaning as R¹ or represents an alkyl group; Z¹ and Z² each represents a nonmetallic atom group required to form a 5- or 6-membered heterocyclic group; p and q each represents an integer 0 or 1; L₁, L₂ and L₃ each represents a methine group; m represents an integer 0 to 2; X represents an anion; and k represents an integer required to adjust the charge in the molecule to 0. The silver halide photographic material may comprise at least one methine compound represented by the general formula (I) and at least one water-soluble dye.
