    摘要： There is disclosed a silver halide color photographic light-sensitive material capable of providing a dye image having excellent color reproducibility, sharpness and image fastness. The light-sensitive material comprises a support having provided thereon a photographic constituent layer comprising a light-sensitive silver halide emulsion layer containing a yellow dye-forming coupler, a light-sensitive silver halide emulsion layer containing a magenta dye-forming coupler, and a light-sensitive silver halide emulsion layer containing a cyan dye-forming coupler, and non-light-sensitive hydrophilic colloid layers. The above silver halide emulsion layer containing the cyan dye-forming coupler contains at least one cyan dye-forming couplers represented by the following Formula (la), and wherein at least one of the non-light-sensitive hydrophilic colloid layers is provided between the support and the silver halide emulsion layer closest to the support and contains a white pigment in a filling rate of 20 weight % or more:

    wherein Za represents -NH- or -CH(R 3 )-, and Zb and Zc each represents -C(R4) = or -N=; R 1 , R 2 and R 3 each represents an electron attractive group having a Hammett's substituent constant σ p of 0.20 or more, provided that the sum of the σ p values of R 1 and R 2 is 0.65 or more; R 4 represents a hydrogen atom or a substituent, provided that when two R 4 groups are present in the formula, they may be the same or different; X represents a hydrogen atom or a group capable of splitting off upon a reaction with an oxidation product of an aromatic primary amine color developing agent; the group represented by Ri, R 2 , R 3 , R 4 or X may become a divalent group and combine with a polymer higher than a dimer and a high molecular chain to form a homopolymer or a copolymer.

    摘要： An image forming method comprising imagewise exposure and color development of a multilayer silver halide color photographic material comprising a support having thereon at least one silver halide light-­sensitive emulsion layer containing at least one oil-­soluble coupler which is capable of forming a substantially non-diffusible cyan dye upon coupling with an oxidation product of an aromatic primary amine developing agent and which is represented by formula (I), and at least one compound selected from the group consisting of compounds represented by formula (II) or (III) followed by the processing of the multilayer silver halide color photographic material with at least one of a bleaching solution and bleach-fixing solution each having a pH of not higher than 6.3, wherein formula (I), (II) and (III) comprise wherein Y represents -NHCO- or -CONH-; R₁ represents an alkyl group, an aryl group, a heterocyclic group or an amino group; X represents a hydrogen atom, a halogen atom, an alkoxy group or an acylamino group; R₂ represents an alkyl group or an acylamino group, or X and R₂ together represent a non-metallic atomic group necessary for forming a 5-membered, 6-membered or 7-­membered ring; Z represents a hydrogen atom or a group capable of being released at the time of coupling with the oxidation product of the developing agent; R₃ and R₅ each represents a halogen atom, an acyl group, an alkyl- or arylsulfonyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a carbamoyl group, a sulfamoyl group, an alkyl- or arylsulfinyl group, a cyano group, a nitro group or an alkyl group having at least one halogen atom at the α-position; R₄ and R₆ each represents a hydrogen atom, an alkyl group, an aryl group, an alkoxy group, an aryloxy group, an alkylthio group, an arylthio group or an amido group; and the total number of carbon atoms included in the groups represented by R₃ and R₄ or the groups represented by R₅ and R₆ is not less than 8. The color image obtained according to this method does not change in cyan image density after the color development processing and has excellent preservability.
