Silver halide color photographic light-sensitive material which comprises a support having thereon at least one silver halide emulsion layer containing a) an alkoxybenzoylacetanilide DIR coupler having bonded to the coupling active position a group which provides a compound having a development inhibiting property when the group is released from the coupler active position upon the color development reaction, wherein said group is a 4,7-dihalogen-2-benzotriazolyl group and b) an alkoxybenzoylacetanilide yellow dye forming coupler having a 3-hydantoinyl leaving group bonded to the coupling active position to provide, upon exposure and development, color images of improved image sensitivity.
