Abstract
In a silver halide color photographic light-sensitive material which includes at least one layer of each of red-, green-, and blue-sensitive silver halide emulsion layers and a yellow filter layer containing yellow colloidal silver on a support, an average grain size of at least one of the light-sensitive silver halide emulsions is 0.4 .mu.m or less, a maximum absorption peak of yellow colloidal silver in the yellow filter layer appears at 430 to 450 nm, and 1/4 absorption of the maximum absorption at the longer wavelength side occurs within the range of 500 to 560 nm. This photographic light-sensitive material can reduce a fog by the yellow filter layer without degrading other photographic properties.
