Definitions

  • the present invention relates to a color photographic light-sensitive material, particularly to a color photographic light-sensitive material having a high saturation and an excellent hue reproduction.
  • a so-called DIR compound which forms a developing inhibitor or a precursor thereof upon reaction with an oxidation product of a color developing agent, to a silver halide multi-layered color photographic light-sensitive material.
  • a developing inhibitor released from such a DIR compound inhibits developing of other color forming layers and thereby produces an interimage effect to improve the color reproduction.
  • the same effect as the interimage effect can be achieved by adding a colored coupler in an amount larger than that necessary to offset useless absorptions.
  • U.S. Pat. No. 3,672,898 discloses a spectral sensitivity distribution appropriate to mitigate a fluctuation in color reproduction caused by a difference in light sources at photographing. But, this is not good enough to improve the foregoing poor-reproducible colors.
  • a combination of a spectral sensitivity distribution and an interimage effect is disclosed in Japanese Patent O.P.I. Publication No. 34541/1986, in which an attempt is made to improve the foregoing poor-reproducible colors and seems to produce an effect to some extent. Its typical embodiment is to exercise an interimage effect not only from a centroidal wavelength of each of blue-sensitive, green-sensitive and red-sensitive layers as performed in conventional methods, but also from wavelengths other than the centroid of each color sensitive layer.
  • the object of the present invention is to provide a silver halide color photographic light-sensitive material capable of faithfully reproducing bluish purple, bluish green and green without impairing reproduction of skin color.
  • a color photographic light-sensitive material having on a support at least one layer each of blue-sensitive silver halide emulsion layer (hereinafter occasionally referred to as a blue-sensitive layer), green-sensitive silver halide emulsion layer (hereinafter occasionally referred to as a green-sensitive layer) and red-sensitive silver halide emulsion layer (hereinafter occasionally referred to as a red-sensitive layer), wherein a maximum sensitivity wavelength ⁇ R in a spectral sensitivity distribution of said red-sensitive is in a range of
  • a maximum sensitivity wavelength ⁇ G of a spectral sensitivity distribution of said green-sensitive silver halide emulsion layer is in a range of
  • a sensitivity of said green-sensitive layer at 500 nm is larger than one-fourth the sensitivity at the maximum sensitivity wavelength ⁇ G .
  • FIG. 1 is a chart showing color reproductions of the samples on the (a*, b*) plane of the (L* a*, b*) color system.
  • the spectral sensitivity is shown as a function of a wavelength; that is, when a light-sensitive material is exposed to a spectral light from 400 nm to 700 nm at intervals of several nanometers, on the basis of the exposure to give a prescribed density at each wavelength is evaluated a sensitivity of said wavelength.
  • a proper measure can be arbitrarily taken to obtain the foregoing inventive spectral sensitivity distribution in red-sensitive and green-sensitive layers.
  • Use of a spectral sensitizing dye for example, provides such a spectral sensitivity distribution.
  • Types of spectral sensitizing dyes used in these layers are not limited, but good results can be obtained by using the following spectral sensitizing dyes in combination.
  • spectral sensitivity distribution of a red-sensitive layer can be brought into that specified in the present invention by various means, but such a spectral sensitivity distribution is preferably achieved by a red-sensitive emulsion spectrally sensitized by a combined use of at least one of the sensitizing dyes represented by Formula (I) and at least one of the sensitizing dyes represented by Formula (II) or (III).
