ABSTRACT:
A novel silver halide color photographic material comprising on a support at least one light-sensitive emulsion layer and at least one hydrophilic colloidal layer containing a white pigment between said support and said light-sensitive emulsion layer is provided, wherein (i) said white pigment is incorporated in such an amount that the coated amount thereof in said hydrophilic colloidal layer is in the range of 2 g/m.sup.2 or more, at least one of layers constituting said light-sensitive emulsion layer comprises a silver halide emulsion having a silver chloride content of 90 mol % or more and containing at least one of metal complexes of Fe, Ru, Re, Os and Ir in silver halide grains and at least one mercapto heterocyclic compound, (ii) said white pigment is incorporated in such an amount that the density thereof is in the range of 20% by weight or more, at least one of layers constituting said light-sensitive emulsion layer comprises silver bromochloride emulsion grains or silver chloride emulsion grains having a silver chloride content of 90 mol % or more sensitized with a gold compound, and either said light-sensitive layer or said light-insensitive layer comprises at least one of specific compounds represented by the general formulae (I) to (IX) as is defined in claims, or (iii) said white pigment is incorporated in such an amount that the density thereof in said hydrophilic colloidal layer is in the range of 20% by weight or more, at least one of layers constituting said light-sensitive emulsion layer comprises silver bromochloride emulsion grains or silver chloride emulsion grains containing substantially no silver iodide and having a silver chloride content of 95 mol % or more, and the film pH and film pAg of said light-sensitive material are in the range of 5.0 to 6.5 and 6.0 to 10.0, respectively.
