摘要

A silver halide photographic light-sensitive material improved in light fading resistance of cyan dye-images and, particularly, in discoloration resistance in low density area of the images. The photographic material is comprises a support having thereon at least one silver halide emulsion layer and at least one non-light-sensitive layer, and the silver halide emulsion layer contains a cyan-dye forming coupler represented by the following formula [I] or [II] and at least one of the silver halide emulsion layer containing the above cyan-dye forming coupler and the non-light-sensitive layer adjacent to the emulsion layer contains an liquid UV absorbent which is liquid state at an ordinary temperature together with a high boiling organic solvent having the dielectric constant of not more than 0.6 in the ratio by weight of from 0.65 to zero to said UV absorbent contained in said layer.
