    • There is disclosed a silver halide color photographic light-sensitive material which excels in a color reproduction and an image fastness and which has an excellent color developability. The above silver halide color photographic light-sensitive material comprises a support and provided thereon a yellow color-developing light-sensitive silver halide emulsion layer, a magenta color-developing light-sensitive silver halide emulsion layer and a cyan color-developing light-sensitive silver halide emulsion layer each having a different color-sensitivity, wherein the above magenta color-developing light-sensitive silver halide emulsion layer contains at least one of the non-diffusible dye-forming couplers represented by the following Formula (M), a high boiling organic solvent having a dielectric constant of 6.0 or less and a refraction index of 1.50 or less, and at least one of the water insoluble polymers which are obtained by polymerizing at least one of the monomers having an aromatic group: wherein R1 represents a hydrogen atom or a substituent; Z represents a non-metal atomic group which is necessary to form a 5-membered azole ring containing 2 to 4 nitrogen atoms and the above azole ring may contain a substituent (including a condensed ring); and X represents a hydrogen atom or a group capable of splitting off upon a coupling reaction with an oxidation product of a developing agent.
