Abstract

Disclosed is a silver halide color photographic light-sensitive material having at least two green-sensitive silver halide emulsion layers having different sensitivities on a support. The layer having the lowest sensitivity of the green-sensitive layers contains at least one type of coupler represented by Formula (M), and the layer having the highest sensitivity of the green-sensitive layers contains at least on type of coupler represented by Formula (N), Formula (I) or Formula (II), ##STR1## wherein R.sub.1 represents a hydrogen atom or a substituent, Z represents a nonmetallic atom group required to form a 5-membered azole ring containing two to four nitrogen atoms, said azole ring being able to have a substituent including a condensed ring, and X represents a group except for a hydrogen atom, which can split off during a coupling reaction with an oxidized form of a developing agent. Formula (N) represents a compound represented by Formula (M) in which the split-off group X is replaced by a hydrogen atom.
