ABSTRACT:
A silver halide color photographic light-sensitive element comprising a support having thereon at least one interlayer which comprises a solution prepared by dissolving at least one hydrophobic compound, which acts as an ultraviolet ray-absorbing agent, represented by the following general formula (I) in an alkyl phosphoric acid ester represented by the following general formula (III) dispersed in a gelatin-containing hydrophilic colloid which does not contain any dye image-forming agents, in which element color stain resulting from exposure to light is effectively suppressed: ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 may be the same or different, and each represents a hydrogen atom, a halogen atom, a nitro group, a hydroxyl group, an alkyl group, an alkenyl group, an aryl group, an alkoxy group, an acyloxy group, an aryloxy group, an alkylthio group, an arylthio group, an aralkylthio group, a mono- or dialkylamino group, an acylamino group or a 5- or 6-membered heterocyclic ring containing an oxygen or a nitrogen atom and further, R.sup.4 and R.sup.5 may combine to form a 5- or a 6-membered aromatic ring consisting of carbon atoms; ##STR2## wherein R.sup.6, R.sup.7 and R.sup.8 each represents a branched chain alkyl group having 8 or more carbon atoms where the total number of carbon atoms contained in compound (III) is 24 to 40.
