Definitions

  • This invention relates to a color photographic light-sensitive material of a multilayer construction.
  • the present invention achieves an improvement in granularity of dye image grains which are produced by processing a sensitive material, which contains silver halides and nondiffusible couplers as main components, with a first developing solution containing a black-and-white developing agent of pyrazolidone type and subsequent processing of the resulting material with a reversal color developing solution containing a color developing agent of paraphenylenediamine type.
  • a coupler incorporated color photographic light-sensitive material comprises a support coated generally with a nondiffusible cyan-forming coupler incorporated red-sensitive silver halide emulsion layer, a nondiffusible magenta-forming coupler incorporated green-sensitive emulsion layer and a nondiffusible yellow-forming coupler incorporated blue-sensitive emulsion layer.
  • most color photographic light-sensitive materials for taking photographs are constructed of a support, e.g., a cellulose triacetate film, a polyethylene terephthalate film or the like which is provided with a subbing layer in advance and has provided thereon, a red-sensitive layer, a green-sensitive layer and a blue-sensitive layer in that order. Further a yellow filter layer is put in between the green-sensitive layer and the blue-sensitive layer and further, a gelatin protective layer is provided as the topmost layer of the sensitive material.
  • a support e.g., a cellulose triacetate film, a polyethylene terephthalate film or the like which is provided with a subbing layer in advance and has provided thereon, a red-sensitive layer, a green-sensitive layer and a blue-sensitive layer in that order.
  • a yellow filter layer is put in between the green-sensitive layer and the blue-sensitive layer and further, a gelatin protective layer is provided as the topmost layer of the sensitive material.
  • the so-called mixed emulsion e.g., the combination of a high sensitivity emulsion containing relatively coarse grains and a low sensitivity emulsion containing fine grains, is employed as the silver halide emulsion for the purpose of attaining desired gradation.
  • German Patent 1,121,470 and British Patent 923,045 disclose another method of improving granularity of a dye image in which-as described in their respective examples-an emulsion which has been conventionally coated in a single layer is separated into two layers, a high sensitivity emulsion layer and a low sensitivity emulsion layer, which have their sensitivities in the same visible region and which contain their respective nondiffusible couplers which form colors of substantially the same hue, and which are coated in a double layer.
  • Such a method makes it possible to increase the sensitivity of a multilayer color photographic light-sensitive material without deteriorating the granularity in a practically important density range of the gradation curve, and in proportion to this gain in the sensitivity the grain size of the silver halide emulsion can be decreased resulting in the improvement of the granularity.
  • a method can exhibit its effect on improvement of the granularity in a negative-type film which contains a small amount of coupler in its high sensitivity emulsion layer, it is not effective for reversal-type films, because it is necessary for reversal type film to contain a large amount of coupler in its high sensitivity emulsion layer in order to render the gradation hard in a high density range.
  • an emulsion contains grains among which there exists a distribution of sizes, and deterioration of granularity due to coarse grains present in a specific proportion is unavoidable. Accordingly, the improvement in granularity attained by the above-described method is far from being sufficient.
  • a high sensitivity emulsion layer an intermediate sensitivity emulsion layer and a low sensitivity emulsion layer.
  • An object of this invention is to improve the granularity of a multilayer reversal color photographic material.
  • a multilayer silver halide reversal colour photographic material comprising a support bearing at least three silver halide emulsion layers having the same colour sensitivity but different photographic sensitivities, among the emulsion layers at least both the emulsion layer having the highest photographic sensitivity and the emulsion layer having the second highest photographic sensitivity satisfying the following conditions:
  • a grain size and a grain size distribution can be determined according to methods described in T. H. James, The Theory of Photographic Process, the 4th Ed., pp. 100-102 (1977).
  • Reducing iodide contents in the highest sensitivity emulsion layer and the second highest sensitivity emulsion layer to 4.5 mole % or less results in accelerating the progress of development and consequently, such layers become contrasty and an influence of their granularities upon emulsions having lower sensitivities can be diminished.
  • This invention makes it possible to improve the granularity without making the gradation contrasty. Namely, in the density range near 1.0 based on the reversal density which has the greatest influence on qualities of reversal image, the highest sensitivity emulsion layer and the second highest sensitivity emulsion layer both exert a slight influence on the granularity and therefore, this invention can provide reversal images excellent in the granularity.
  • the preferable iodide content in the highest sensitivity emulsion layer and/or the second highest sensitivity emulsion layer is within the range of 0.5 mole % to 3.0 mole %.
  • a particularly preferable emulsion is one which has such a grain size distribution that 90% or more, by number or by weight, of the whole silver halide grains in the emulsion have sizes which are within ⁇ 40% of its mean grain size.
  • This invention can produce satisfactory results in any of the sensitive emulsion layers, such as a red-sensitive emulsion layer, a green-sensitive emulsion layer or a blue-sensitive emulsion layer.
  • a red-sensitive emulsion layer such as a red-sensitive emulsion layer, a green-sensitive emulsion layer or a blue-sensitive emulsion layer.
  • it has a great effect in a red-sensitive emulsion layer and a green-sensitive emulsion layer in which difference in granularity is more liable to be perceived.
  • an emulsion layer having one kind of color sensitivity has three or four constituent layers differing in photographic sensitivity, and the constituent layers are arranged nearer to the support in order of decreasing sensitivity.
  • a difference in photographic sensitivity between the highest sensitivity emulsion layer and the second highest sensitivity emulsion layer ranges from 0.2 to 1.0, preferably from 0.3 to 0.8, expressed in terms of logarithmic units.
  • the preferable difference in photographic sensitivity between the second highest sensitivity emulsion layer and another emulsion layer whose sensitivity ranks next and a preferable difference in photographic sensitivity between the low sensitivity emulsion layers are from 0.3 to 1.5, expressed in terms of logarithmic -units.
  • a mole ratio of silver to coupler in the highest sensitivity emulsion layer is smaller than that in the second highest emulsion layer. It is especially preferable to control the ratio of silver to coupler in the higher sensitivity emulsion layer to a lower value than that in the lower sensitivity emulsion layer.
  • both silver iodobromide and silver iodochlorobromide can be incorporated.
  • a photographic emulsion of this invention no particular regard need be paid to the mean grain size of silver halide grains to be contained therein (the mean grain size being determined by averaging grain sizes based on the projection area wherein a grain diameter in case of spherical or nearly spherical grains and an edge length in case of cubic grains are taken as the grain sizes).
  • the mean grain size being determined by averaging grain sizes based on the projection area wherein a grain diameter in case of spherical or nearly spherical grains and an edge length in case of cubic grains are taken as the grain sizes.

  • Removal of the soluble salts from the silver halide emulsion is, in general, carried out after the formation of the silver halide or after physical ripening.
  • the removal can be effected using the well-known noodle washing method which comprises gelling the gelatin, or using a sedimentation process (thereby causing flocculation in the emulsion) taking advantage of a sedimenting agent such as a polyvalent anion-containing inorganic salt (e.g., sodium sulfate), an anionic surface active agent or an anionic polymer (e.g., polystyrene sulfonic acid), or a gelatin derivative (e.g., an aliphatic acylated gelatin, an aromatic acylated gelatin, an aromatic carbamoylated gelatin or the like).
