Abstract
A silver halide photographic light-sensitive material is disclosed, which is improved in stability of cyan dye image formed therein. The light-sensitive material comprises a support having thereon a silver halide emulsion layer containing oleophilic dispersed particles. The particles comprises a cyan coupler represented by the following Formula I, an organic solvent selected from phthalic esters having a dielectrical constant of not more than 6.0 and a polymer compounds which is insoluble in water and soluble in a organic solvent: ##STR1## wherein R.sub.1 is a ballast group, R.sub.2 is an alkyl group having 2 or more carbon atoms and Z.sub.1 is a hydrogen atom or a substituent capable of splitting off upon reaction with the oxidation product of a color developing agent.
