Abstract
A silver halide color photographic light-sensitive material comprising a support having thereon a lower-speed emulsion containing a phenol cyan coupler and a higher-speed emulsion containing a naphthol cyan coupler. Both the lower-speed emulsion and the higher-speed emulsion have the same color sensitivity.
Claims21
A silver halide color photographic light-sensitive material comprising a support having thereon one or more light-sensitive silver halide emulsion layers, wherein at least one of said light-sensitive silver halide emulsion layers contains a phenol-type cyan coupler having at the second position of the benzene nucleus thereof a group selected from the group consisting of a phenol-ureido group, a naphthyl ureido group and a heterocyclic ureido group, and having at the fifth position thereof an acylamino group, and at least one of said light-sensitive silver emulsion layers contains a naphthol-type cyan coupler which is substantially colorless and has a hydrogen atom or a group capable of splitting off a compound which does not inhibit the development of the coupling reaction at a coupling position with the oxidized product of an aromatic primary amine color developing agent,
- wherein said phenol-type cyan coupler is incorporated into a lower-speed emulsion layer having a color sensitivity and said naphthol-type cyan coupler is incorporated into a higher-speed emulsion having the same color sensitivity.
