Definitions

  • the present invention relates to a silver halide light-sensitive photographic material with improved color reproducibility and image preservability.
  • 5-pyrazolone ring compounds have been widely employed as a magenta coupler.
  • 5-pyrazolone magenta couplers have poor reproducibility for brilliant blue, since a dye formed therefrom has a yellow component generated by an unnecessary absorption around 430 nm.
  • a recently developed pyrazoloazole magenta coupler unlike conventional 5-pyrazolone magenta couplers, has an advantage of improved color reproducibility, since a dye formed therefrom has no secondary absorption in around 430 nm.
  • this coupler is inferior to 5-pyrazolone magenta couplers in image preservability, especially in a light fastness as is known well, and the improvement thereof is expected.
  • Japanese Patent Publication Open to Public Inspection (hereinafter abbreviated as "Japanese Patent O.P.I.

  • the 2,5-diacylamino cyan coupler has an insufficient reproducibility for brilliant green, since a dye formed therefrom has a maximum absorption shifted to a shorter wavelength range and has a significant secondary absorption in around 550 nm, and in order to achieve the sufficient reproducibility of a green color, the other cyan couplers have to be used in combination, which in turn results in badly affecting the improvement of the dark fading property.
  • the phenol cyan coupler having an alkyl group with 2 or more carbon atoms at the 5-position has more improved dark fading property, though still unsatisfactory, than the conventional phenol cyan couplers having a methyl group at the 5-position.
