摘要： There is disclosed a silver halide color photographic light-sensitive material having at least one photographic constitutional layer on a support, wherein at least one reducing agent for color formation, which is a specific hydrazine compound, at least one dye-forming coupler, and at least one high-boiling-point organic solvent whose electron-donative parameter .DELTA..nu..sub.D at 25.degree. C. is 80 or more, are contained in at least one of said photographic constitutional layers. The above light-sensitive material enables low replenishment and reduced discharge of a color developer; can form colors favorably even when the coating film's pH is low; and is reduced in stain due to long-term storage of the light-sensitive material or stain after the processing of the light-sensitive material.
