    • A silver halide color light-sensitive material containing a cyan coupler which provides an excellent hue and an improved fastness at a low color-developing area and which has small change in a color developing density, which is caused by change of a composition of a blix solution and provides a small fog in a cyan color at a non-exposed area in a continuous processing. The silver halide color light-sensitive material contains at least one cyan coupler represented by the following Formula (I) in at least one layer on a support: wherein Y represents --N.dbd. or --C(R.sub.3).dbd.; X represents a hydrogen atom or a group which splits off upon a coupling reaction with an oxidized product of a color developing agent; Z represents a non-metallic atomic group necessary for forming an alicyclic group or a heterocyclic ring; R.sub.1, R.sub.2 and R.sub.3 each represents a hydrogen atom or a substituent; and R.sub.1 contributes to form an unsaturated bond in a ring formed by Z or combined with the atoms on the ring formed by Z to form a ring.
