Definitions

  • the present invention relates to a method for forming a color image which enables rapid processing by efficient color formation using silver at a reduced coverage.
  • a method for forming color images is known in which three kinds of couplers, viz., yellow, magenta, and cyan, are incorporated into light-sensitive layers, respectively, and after imagewise exposure the light-sensitive layers are processed with a color developing solution containing an aromatic primary amine color developing agent, the oxidation product of which can undergo the coupling reaction with couplers to produce developed colors.
  • a color developing solution containing an aromatic primary amine color developing agent, the oxidation product of which can undergo the coupling reaction with couplers to produce developed colors.
  • One such method consists of using an additive capable of accelerating color formation by speeding up penetration of a color developing agent into oil droplets of coupler dispersions, because it is essential at the final stage of forming dyes by coupling with couplers that a color developing agent itself is incorporated in oil droplets in which the couplers are dispersed.
  • an additive capable of accelerating color formation by speeding up penetration of a color developing agent into oil droplets of coupler dispersions, because it is essential at the final stage of forming dyes by coupling with couplers that a color developing agent itself is incorporated in oil droplets in which the couplers are dispersed.
  • various compounds have been known, especially benzyl alcohol, due to its great effect upon acceleration of color formation. Therefore, benzyl alcohol has so far been used in the development-processing of various kinds of color photographic materials, and at present it is prevailingly used in processing color paper.
  • Benzyl alcohol though dissolved in water to some extent, is poor in solubility, so the combined use with diethylene glycol, triethylene glycol, or an alkanolamine has been widely carried out in order to increase the solubility.
  • solubility of benzyl alcohol is not yet sufficient even when the above-described solvent, such as diethylene glycol, is used together, so the insufficiency of benzyl alcohol in solubility is responsible for much time and trouble required in preparing a developing solution.
  • benzyl alcohol brought into the bath subsequent to the developing bath namely a bleaching bath or a bleach-fix bath, together with other ingredients of a developing solution, and accumulated therein, is one of the causes of conversion of cyan dyes of some types into the corresponding leuco compounds, to result in lowering of color density of the developed image.
  • accumulated benzyl alcohol tends to cause insufficient washing-out of ingredients of a developing solution, particularly a color developing agent, in the washing step, and these residual ingredients result sometimes in deterioration of image-keeping quality.
  • a color photographic light-sensitive material in which the total coverage of silver halide contained in silver halide emulsion layers is 0.77 g/m2 on a silver basis, and the molar ratio of the silver halide with respect to a yellow coupler of a blue-sensitive emulsion layer is 5/1 is used.
  • a method for forming a color image which comprises imagewise exposing a color photographic material containing a reflective support having thereon at least one blue-sensitive silver halide emulsion having substantially no iodide content and associated with a yellow dye-forming coupler, at least one green-sensitive silver halide emulsion layer having substantially no iodide content and associated with a magenta dye-forming coupler and at least one red-sensitive silver halide emulsion layer having substantially no iodide content and associated with a cyan dye forming coupler wherein at least one of said blue-sensitive emulsion layer, at least one of said green-sensitive emulsion layer and at least one of said red-sensitive emulsion layer contains said silver halide in a ratio of from 1/1 to 4.5/1 moles with respect to the color forming coupler and said photographic material has a total coverage of silver halide contained in all of said silver halide emulsion layers of 0.78 g/

  • silver halide emulsions are a silver chloride emulsion or a silver chlorobromide emulsion having a chloride content of more than 80 mol%, preferably more than 90 mol%.
  • color developing solution containing substantially no benzyl alcohol as used in the present invention is intended to include developing solutions containing benzyl alcohol in amounts of not more than 0.5 ml per l thereof, preferably those not containing benzyl alcohol at all.
  • the molar ratio of the silver halide to the color coupler it is necessary for the molar ratio of the silver halide to the color coupler to range from 1/1 to 4.5/1, although the molar ratio between the above-described components ranges from 3/1 to 6/1 in various conventional color photographic materials, particularly in color paper, in order to make them develop colors up to practically sufficient densities, taking into account the stoichiometric equivalency of color couplers, namely 2 or 4 in usual cases.
  • the range of the molar ratio in the present invention lies somewhat lower than the conventional one. Accordingly, the molar ratio in the present invention ranges more preferably from 1.5/1 to 3.5/1, and most preferably from 2/1 to 3/1.
  • the total coverage of silver halides in the color photographic material of the present invention is controlled to 0.78 g/m2 or less, and preferably 0.72 g/m2 or less, on a silver basis.
  • the individual layers may have any silver coverage, provided that the total silver coverage meets the above-described condition. However, a silver coverage in the range of from 0.1 to 0.4 g/m2 is preferable for each light sensitive layer.
  • any silver coverage will do as to each constituent layer, as long as the sum of silver coverages of the individual constituent layers is within the range of from 0.1 to 0.4 g/m2.
  • the most preferable silver coverage of each light-sensitive layer ranges from 0.15 to 0.35 g/m2.
  • the emulsion to be employed in the present invention may be a polydispersed system or a monodispersed system, and the mean grain size thereof may be large or small.
