Definitions

  • This invention relates to a method for processing a light-sensitive color photographic material suitable for full color photographing, particularly to a method for processing a negative-type light-sensitive silver halide color photographic material of which at least one color sensitive layer is a single layer.
  • Having broad exposure latitude refers to the fact that the gradation is good over wide exposure dose range from the shadow portion with little exposure dose to the high-light portion with much exposure dose in the so-called characteristic curve in which the exposure dose is taken on the axis of abscissa and the color formed density on the axis of ordinate.
  • Color negative film as different from color reversal film or color paper, is a light-sensitive material for which gradation is demanded to be strictly controlled over wider range of exposure dose, and for that reason, color negative films for photography commercially available at the present time are made to have an overlaid constitution comprising a plurality of emulsion layers of higher sensitivity layer containing greater grain sizes and lower sensitivity layer containing smaller grain sizes for the respective color sensitive layers to the light of blue color, green color and red color. Further, the so-called DIR compound for forming consequently a developing inhibitor through the reaction with the oxidized product of the developing agent is employed.
  • Such technique is inherent in color negative film, and particularly the DIR compound improves not only gradation but also sharpness, graininess, color reproducibility, and is essential in color negative film.
  • a color negative film has an overlaid constitution by use of a plurality of emulsion layers containing silver halide grains with different grain sizes as described above, and further that it further strictly controls gradation by use of a DIR compound, stability to processing conditions is inferior (because a color negative film is processed under various laboratories as compared with color reversal film, developing processing is conducted under processing conditions with great width of fluctuation. Therefore, a color negative film is particularly demanded to have high degree of stability to fluctu ation in processing conditions.), etc., it has drawbacks such that gradation is deteriorated, color reproducibility and tone reproducibility are deteriorated, etc.
  • the present invention has been accomplished in view of the task of the prior art as mentioned above, and its object is to provide a method for processing a light-sensitive silver halide color photographic material which can obtain sufficient color formed density to give an image excellent in tone reproducibility, color reproducibility and also sharpness, even if developing processing is made more rapid.
