ABSTRACT:
A silver halide color photographic light-sensitive material comprising a support having provided thereon at least one silver halide emulsion layer, wherein the silver halide color photographic light-sensitive material contains at least one dye forming coupler represented by the following formula (I): ##STR1## wherein R.sub.1 represents a substituted or unsubstituted aliphatic group, a substituted or unsubstituted aromatic group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted alkylthio group, a substituted or unsubstituted arylthio group or a substituted or unsubstituted amino group; X.dbd.Y represents C.dbd.O, C.dbd.NR.sub.2, P.dbd.O or S.dbd.O; R.sub.2 represents an aliphatic group or an aromatic group; Z represents a group capable of being released upon a reaction with the oxidation product of a developing agent; m and n each represents an integer of 1 or 2; R.sub.1 and R.sub.2, R.sub.1 and Z or R.sub.2 and Z may be combined with each other to form a ring; and when m is 2, two R.sub.1 's may be the same or different, or may be combined with each other to form a ring.
The dye forming coupler represented by the formula (I) provides a yellow dye having excellent hue, a large molecular extinction coefficient and storage stability, and the silver halide color photographic light-sensitive material containing the yellow dye forming coupler is excellent in color reproducibility, sharpness and color image fastness.
