Abstract
Abstract A silver halide photographic light-sensitive material is disclosed, which is excellent in light discoloration resistance and is more particularly capable of keeping its color balance and reproducing long life color images. The photographic material comprises a support, at least three light-sensitive silver halide emulsion layers containing a yellow, magenta, and cyan coupler, respectively, and at least one non-light-sensitive layer being provided at a further side of the emulsion layer being provided at the furthest position from the support. The non-light-sensitive layer contains at least three kinds of UV absorbers represented by the general formula [UV-I], provided that at least one of the UV absorbers is in a liquid state at 30° C. and at least two UV absorbers are in a solid state at the same temperature. ##STR1## And the emulsion layer containing the yellow coupler contains a compound represented by the general formula [A]: ##STR2##
