Definitions

  • At least one correcting layer of a fine-grained silver halide emulsion having a grain diameter below 114. is incorporated in the material. It may be disposed over the uppermost, under the lowermost or between the active emulsion layers.
  • the correcting layer may be spectrally sensitized or unsensitized, may be ripened with gold and may include a single halide or a mixture of several.
  • the invention relates to a multi-layer material for color reversal processes, whose color reproduction is improved by incorporation of fine-grained silver halide emulsions.
  • the quality of the color reproduction of a multi-layer reversal material in the red and blue may be determined, besides by means of practical exposures, also by exposing a sensitometer wedge with red or blue light and measuring the wedges, developed in a color reversal developer, on a densitometer behind red, green and blue filters.
  • FIGS. 1 to 4 are illustrated such densograms of filter separations for a highly sensitive color reversal film of ca. 23 DIN and a moderately sensitiveone of ca. 18 DIN.
  • the good color brilliancy of the moderately sensitive film is expressed in Diagrams 2 and 4 by nearly horizontally proceeding curves behind green and blue filters with red separation and by a curve rise with a peak behind green and red filters with blue separation.
  • the poorer color brillancy of the high sensitive film (FIGS. 1 and 3) is characterized by a strong decline of the corresponding curves with red separation and by the disappearance of the curve rise with respect to blue separation.
  • cyanine dyes customarily used in color emulsions, may be employed for the red, green, and blue-green spectral range.
  • the amount of sensitizer is so chosen that the improvement of the color reproduction is optimum and empirically is between 30 and 300 mg. dye per mol silver halide.
  • Fine-grained silverbromoiodine emulsions preferably silverchloride, and silverbromochloride emulsions with a diameter of the silver halide grains of less than 1,1. are suitable as the emulsions for the correcting layer.
  • the extent of the influence on the color reproduction is dependent on the composition and the fine-granulation of the correcting layer and on the silver content of the correcting layer.
  • the optimum coating with silver chloride and silverbromochloride emulsions is under 0.8 g. silver halide per square meter.
  • FIG. 1 is a densogram of a red filter separation for a highly sensitive color reversal film
  • FIG. 2 is a densogram similar to FIG. 1 for a moderately sensitive color reversal film
  • FIG. 3 is a densogram of a blue filter separation for a highly sensitive color reversal film
  • FIG. 4 is a densogram similar to FIG. 3 for a moderately sensitive color reversal film
  • FIG. 5 is a schematic view in elevation of a multilayer photographic material which illustrates one embodiment of this invention.
  • FIG. 6 is a schematic view in elevation of a multilayer photographic material which illustrates another embodiment of this invention.
  • FIG. 7 is a schematic view in elevation of a multilayer photographic material which illustrates a further embodiment of this invention.
  • Example 1 A high sensitive color reversal film with ca. 23 DIN and normal layer sequence is first synthesized without protective layer as shown in FIG. 5. Mixtures of a high sensitive, coarsely grained silverbromoiodide emulsion and a moderately sensitive, finely grained silverbromoiodide emulsion, which is ripened with gold, are employed as the emulsions for the cyan layer 10 and magenta layer 12. The yellow layer 14 arranged at the top contains only the coarsely grained emulsion. Aside from the customary stabilizers, wetting agents, hardening agents, and plasticizers, the individual layers containing the following color couplers and sensitizers:
  • Cyan layer a-oxynaphthoyl-N-octadecylamide, 5,5-dichloro-3,3-di(fl carboxyethyl) 9 ethylthiacarbocyanine iodide
  • Magenta layer 1-(2',4,6 '-trichlorophenyl)-3-(4"-chloro- 6"-tetradecylphenoxycarbonamido) pyrazolone 5-(3-ethyl-2,3-benzothiazolylidene) 3 carboxymethyl (rhodanine)
  • Yellow filter layer 1-(2',4',6'-trichlorophenyl-3-undecyl- 4 (2"-carb oxymethoxycinnamal) -pyrazolone- 5
  • Yellow layer 2-tetradecyloxy-a-benzoyl-acetanilide Four different correcting layers were coated on the top yellow layer of the high sensitive multilayer material
  • the first layer 16 consisted only of a customary gelatin protective layer.
  • the three others 18, 20 and 22 contained, in different dilution with gelatin, a fine-grained, goldripened silverbromoiodide emulsion with 4.1 mol percent AgI and ca. 0.5;; maximum grain diameter.
  • To this emulsion were added 250 mg. of the red sensitizer, such as described for the cyan layer, per mol silver halide.
  • Example 2 The color reversal material differs from Example 1 in that in the cyan layer and magenta layer 12 there was used only a moderately sensitive silverbromoiodide emulsion instead of a mixture of highly and moderately sensitive emulsion; but in the yellow layer there was used the same coarse-grained emulsion as in Example 1.
  • the combined sensitivity of the material according to Example 2 was lower by 3 DIN than that of Example 1. Besides this, the arrangement of layers and the correcting layers on top of the yellow layer correspond to those of Example 1.
  • the test results are illustrated in the following table.
  • Example 3 The material diflers from that of Example 2 in that the correcting layers 18A, 20A and 22A are inserted between the yellow filter layer 16A and yellow layer 14A. Only the red separation was measured.
  • Example 4 The material differs from that in Example 1 in that for the correcting layers 18, 20 and 22 there is employed a fine-grained silver bromochloride emulsion with 75 mol percent AgCl and 25 mol percent AgBr, sensitized with the red sensitizer of Example 1.
  • a color reversal film contained, as in Example 2, for the cyan layer 10 and magenta layer 12, a semi-sensitive silver bromoiodide emulsion; in the uppermost arranged yellow layer 14, a coarsely grained emulsion. Onto the yellow layer 14 layers of varying composition were coated.
  • the first layer 16 consisting of a customary gelatin protective layer, layer 18 of a gelatin diluted, fine-grained, gold-ripened, uusensitized silverbromoiodide emulsion according to Example 1, and layer 20 of the same emulsion but sensitized for the red spectral range with 5,5 '-dichloro- 3,3'-di-(5-carboxyethyl) 9 ethylbenzothiocarbocyanine iodide. There is no layer 22 in this example.
  • Example 6 TABLE 6 A D Gr/D Gr Red separation, No. Correcting layer percent 1 Without 33 2. Under the cyan layer 19 The effect of the correcting layer under the cyan layer is clearly apparent.
  • a multilayer photographic material incorporating color components for color reversal processes, and having a number of combined coupler-containing and dyeproducing silver halide emulsion layers in a layer arrangement, said arrangement being characterized by the disposition of at least one additional layer, comprising a spectrally sensitized, fine-grained silver halide emulsion with a grain diameter below I in direct proximity to one of said combined coupler-containing and dye-producing silver halide emulsion layers taking part in the layer arrangement whereby the color reproduction of said material is improved, the spectral sensitivity of said additional layer being uncoordinated with the sensitivity of the combined coupler-containing and dye-producing silver halide emulsion layers and therefore said additional layer does not contribute to the picture image production but advantageously influences fog and exposure nuclei in adjacent dye producing layers to thereby improve the color reproduction of said material.
  • a multilayer photographic material incorporating color components for color reversal processes, and having an uppermost and undermost layer each containing color coupler and silver halide emulsion, said material being characterized by the arrangement of an additional layer consisting of an unsensitized, fine-grained silver halide emulsion with a grain diameter below In over said uppermost or under said lowermost emulsion layer containing color coupler and silver halide emulsion whereby the color reproduction of said material is improved, the spectral sensitivity of said additional layer being uncoordinated with the sensitivity of the uppermost of lowermost color coupler and silver halide emulsion layers and therefore said additional layer does not contribute to the picture image production but advantageously influences the fog and exposure nuclei in adjacent color coupler and silver halide emulsion-containing layers to thereby improve the color reproduction of said material.
  • a multilayer photographic material as set forth in claim 1 also including an unsensitized additional layer.
