  • the pyrazolone coupler used in the invention has the following valuable features:
  • the coupler of the invention is a two equivalent coupler which theoretically requires only two equivalents of silver halide, as an oxidizer, for forming one molecule of a colored dye.
  • the required silver halide can be reduced to about half of that in using a prior art four equivalent pyrazolone type coupler, thus not only halving the silver halide contained in a light-sensitive material and reducing the production cost of the light-sensitive material, but also reducing the light scattering due to the emulsion grains and improving the sharpness of the image.
  • the coupler of the 4-position-substituted S-pyrazolone type used in the invention can be converted into an azomethine dye in a high yield by the oxidizing and coupling reaction using an exposed silver halide as an oxidizer.
  • Some of the four equivalent couplers used in the prior art have a low conversion yield into the dye, since the leuco dye as an intermediate product produces side reactions such as azine ring formation.
  • the coupler of the 4-position-substituted S-pyrazolone type used in the invention can be converted into an azomethine dye with a high yield, since reaction procession is not through such a reactive intermediate product.

  • a bleaching and fixing bath containing a silver complex salt fonning agent and weak oxidizer such as a ferric chelate of EDTA or a bleaching bath containing a mercuric salt such as mercuric chloride is possible and, consequently, it is easy to shorten the time for all the processings of color development as well as to solve the problem of environmental pollution in processing solution discharge.
  • the 4-position-substituted S-pyrazolone coupler used in the invention is inactivated by carbonyl compounds such as aldehydes and ketones to a less extent, while the 4-position-non-substituted 5-pyrazolone coupler used in the prior art, in particular, in an emulsion layer is changed into a compound of low color forming reactivity such as a methylol or methylene-bis compound by formaldehyde in the air, which often does not provide sufficient color forming property during color development.
  • a change in the coupler markedly reduces the color reproduction of a color light-sensitive material.
  • One feature of the color light-sensitive material of the invention is that the material is hardly influenced by such chemicals.
  • the 4-position-substituted S-pyrazolone of the invention has the advantages, when used for conventional color light-sensitive materials as described in the Examples, that the stability during the passage of time is high in an emulsion film and, in particular, the color forming property is reduced to a lesser extent even after the passage of time at low temperature under high humidity, as compared with the above described known couplers.
