Disclosed is a silver halide photographic material containing a compound of formula (1) or (2):
(DYE)̵(̵G)n (1)
(DYE)̵(̵G⁻)n (2)
where DYE represents a methine dye residue; G and G⁻ each represent a substituent for the methine dye residue, and are represented by formulae (3) and (4), respectively; and n represents an integer of from 1 to 6.
-T¹-G¹NHG² (3)
-T¹-G¹N⁻G² (4)
where T¹ represents a divalent linking group; G¹ represents a carbonyl group, a sulfinyl group, or a sulfonyl group; G² represents -CO-T², -SO-T², -SO₂-T², or a cyano group; and T² represents a monovalent group. The spectral sensitivity of the material is high, and the material has few residual color after processed.
