Definitions

  • the present invention relates to a color reversal silver halide light-sensitive photographic material, and more particu­larly to a color reversal light-sensitive material which is improved so that its photographic characteristics are hardly affected by fluctuation in processing and which is excellent in the color reproducibility.
  • color reversal light-sensitive materials For color reversal light-sensitive materials, various characteristics are required, and above all, in the noticeable high-quality-image-oriented trend in recent years, importance is attached particularly to the color reproducibility.
  • color reversal light-sensitive materials since it is prac­tically impossible to apply to them the technique of compensat­ing the formed dyes' secondary absorptions by such colored couplers as used in color negative materials, the color-form­ing materials in themselves are required to form high color-­purity dyes.
  • pyrazoloazole-type magenta cou­plers since their secondary absorption is extremely small, are advantageous in the color reproducibility.
  • Another desirable characteristic for the color reversal light-sensitive material is that the material be stable against fluctuations in color developing conditions.
  • the residual silver halide remaining undeveloped in the first development, after being fogged, is used for color development; ⁇ thus the color reversal process is complex as compared to color negative materials, and this complexity is considered to result in increasing fluctuations in the developing conditions (including e.g., pH of the developer solution) of the color reversal light-sensitive material, thereby making its photo­graphic characteristics increasingly unstable.
  • a reversal silver halide photographic light-­sensitive material comprising a support and, provided thereon, photographic component layers including at least two silver halide emulsion layers different in the spectral sensitivity from each other, in which at least one layer of the silver halide emulsion layers contains a pyrazoloazole-type magenta coupler, and at least one layer of the photographic component layers contains a compound which is capable of releasing a development inhibitor (hereinafter referred to as 'DIR compound').
  • Japanese Patent Publication Open to Public Inspection (hereinafter referred to as Japanese Patent O.P.I. Publica­ tion) No. 262158/1985 discloses the use of both of pyrazolo­azole-type magenta coupler and a DIR compound capable of releasing a diffusible inhibitor component.
  • This publication describes the improvement of color reproducibility, but makes no mention of improving photographic characteristics so as to be stable against fluctuations in color reversal processing. Accordingly, the improvement to make the photographic charac­teristics stable against fluctuations in processing, which is one of the objects of the present invention, cannot be expected at all to be accomplished by those techniques alone which have hitherto been disclosed.
