Abstract:
A silver halide color photographic light-sensitive material, having at least one each of blue-, green-, and red-sensitive emulsion layers containing yellow, magenta, and cyan couplers, respectively, on a support; wherein said blue-sensitive emulsion layer contains at least one coupler of formula (I); and wherein the light-sensitive material satisfies expression a-1) and/or b-1): wherein, Q forms a 5- to 7-membered ring with the —N═C—N(R1)-; R1 and R2 each are a substituent; m is 0 to 5; and X is a hydrogen atom, or a coupling split-off group; 0.5≦Dmax(UV)/Dmin(UV)≦1.1 a-1) wherein Dmax(UV)/Dmin(UV) is the smallest of the value in a wavelength range of 340 to 450 nm; 1300≦(B−C)/A≦20000 b-1) wherein B is yellow Dmax, C is yellow Dmin; and A is an amount mol/m2 of the coupler of formula (I).
