Definitions

Structurally different dyes are usually used for the spectral sensitization of the blue, green and red spectral range (see, for example, DE-A-42 31 770, DE-A-44 23 129, DE-A-44 04 003, DE-A-44 33 637, DE-A-44 34 971.
EP-A-0 409 019 describes and claims a color photographic recording material with improved color rendering, which is achieved in that both the green-sensitive and the red-sensitive silver halide emulsion layers by using one or more so-called gap sensitizing dyes provide additional sensitization to light from the gap between the neighboring main spectral ranges green and red.
the invention relates to a color photographic recording material with a layer support and at least one red-sensitive one arranged thereon Silver halide emulsion layer with a cyan coupler, at least one green-sensitive silver halide emulsion layer with a magenta coupler, at least one blue-sensitive silver halide emulsion layer with a yellow coupler and, if appropriate, further non-light-sensitive layers, characterized in that at least one of its red-sensitive silver halide emulsion layers and at least one of its green-sensitive silver halide dye-sensitizing emulsion layers and a cyanogen colorant emulsion sensitizing layer contain, which has an absorption maximum in the range of 515 - 550 nm, preferably in the range of 517 - 540 nm in methanolic solution, the absorption maximum of the additional cyanine dye in the red-sensitive silver halide emulsion layer and the absorption maximum of the additional cyanine dye in the green-sensitive layer,
the additional cyanine dyes mentioned are preferably carbocyanines which carry an alkyl radical substituted by an acid group on at least one of the (two) ring nitrogen atoms.
Particularly suitable examples of these cyanine dyes belong to the class of benzimidazole carbocyanines or the class of oxathiacarbocyanines.
the additional cyanine dye in the red-sensitive silver halide emulsion layer is identical to the additional cyanine dye in the green-sensitive silver halide emulsion layer.
Cyanine dyes which match the structure of the dye chromophore are regarded as "identical", even if the counterions which may be present to balance the charge do not match.
color photographic materials are color negative films, color reversal films, color positive films, color photographic paper, color reversal photographic paper, color sensitive materials for the color diffusion transfer process or the silver color bleaching process.
the photographic materials consist of a support on which at least one light-sensitive silver halide emulsion layer is applied. Thin films and foils are particularly suitable as supports. An overview of carrier materials and auxiliary layers applied to their front and back is shown in Research Disclosure 37254, Part 1 (1995), p. 285.
the color photographic materials usually contain at least one red-sensitive, green-sensitive and blue-sensitive silver halide emulsion layer and, if appropriate, intermediate layers and protective layers.
these layers can be arranged differently. This is shown for the most important products:
Color photographic films such as color negative films and color reversal films have 2 or 3 red-sensitive, cyan-coupling silver halide emulsion layers, 2 or 3 green-sensitive, purple-coupling silver halide emulsion layers and 2 or 3 blue-sensitive, yellow-coupling silver halide emulsion layers on the carrier in the order given below.
the layers of the same spectral sensitivity differ in their photographic sensitivity, the less sensitive sub-layers generally being arranged closer to the support than the more sensitive sub-layers.
a yellow filter layer is usually applied between the green-sensitive and blue-sensitive layers, which prevents blue light from reaching the layers below.
Color photographic paper which is generally much less sensitive to light than a color photographic film, usually has a blue-sensitive, yellow-coupling silver halide emulsion layer, a green-sensitive, purple-coupling silver halide emulsion layer and a red-sensitive, cyan-coupling silver halide emulsion layer on the support in the order given below; the yellow filter layer can be omitted.
Deviations in the number and arrangement of the photosensitive layers can be carried out in order to achieve certain results. For example, all highly sensitive layers can be combined in one layer package and all low-sensitivity layers can be combined in another layer package in a photographic film in order to increase the sensitivity (DE 25 30 645).
Binding agents, silver halide grains and color couplers are essential components of the photographic emulsion layers.
Photographic materials with camera sensitivity usually contain silver bromoiodide emulsions, which may also contain small amounts of silver chloride.
Photographic copying materials contain either silver chloride bromide emulsions with up to 80 mol% AgBr or silver chloride bromide emulsions with over 95 mol% AgCl.
the maximum absorption of the dyes formed from the couplers and the color developer oxidation product is preferably in the following ranges: yellow couplers 430 to 460 nm, purple couplers 540 to 560 nm, cyan couplers 630 to 700 nm.
hydrophobic color couplers but also other hydrophobic components of the layers, are usually dissolved or dispersed in high-boiling organic solvents. These solutions or dispersions are then emulsified in an aqueous binder solution (usually gelatin solution) and lie after drying the layers as fine droplets (0.05 to 0.8 ⁇ m diameter) in the layers before.
aqueous binder solution usually gelatin solution
the non-light-sensitive intermediate layers which are generally arranged between layers of different spectral sensitivity, can contain agents which prevent undesired diffusion of developer oxidation products from one light-sensitive layer into another light-sensitive layer with different spectral sensitization.
Suitable compounds can be found in Research Disclosure 37254, Part 7 (1995), p. 292 and in Research Disclosure 37038, Part III (1995), p. 84.
the photographic material can also contain UV light-absorbing compounds, whiteners, spacers, filter dyes, formalin scavengers, light stabilizers, antioxidants, D min dyes, additives to improve the stability of dyes, couplers and whites as well as to reduce the color fog, plasticizers (latices), Contain biocides and others.
Suitable compounds can be found in Research Disclosure 37254, Part 8 (1995), p. 292 and in Research Disclosure 37038, Parts IV, V, VI, VII, X, XI and XIII (1995), p. 84 ff.
the layers of color photographic materials are usually hardened, i.e. the binder used, preferably gelatin, is crosslinked by suitable chemical processes.
Suitable hardener substances can be found in Research Disclosure 37254, Part 9 (1995), p. 294 and in Research Disclosure 37038, Part XII (1995), page 86.
a color photographic recording material for color negative color development was produced (layer structure 1A - comparison) by applying the following layers in the order given to a transparent cellulose triacetate support. The quantities given relate to 1 m 2 . The corresponding amounts of AgNO 3 are given for the silver halide application. All silver halide emulsions per 100 g of AgNO 3 were stabilized with 0.1 g of 4-hydroxy-6-methyl-1,3,3a, 7-tetraazaindene.
the spectral sensitization was changed in the manner listed below:
the layer structures 1A to 1F were processed using a color negative process, which is described in "The British Journal of Photography” 1984, pages 597 and 598.
the sensitivities E purple and E blue-green of the layer structures 1B to 1F according to the invention are compared in Table 1 to those of the comparison layer structure 1A.
Table 2 summarizes the results of the Cielab measurements, which were used to characterize the color shift. Only the colors that are changed particularly strongly are mentioned.
Cielab measurements have long been used for the colorimetric description of CN films. The method is described in detail, for example, in RWG, Hunt “The Reproduction of Color “, Fountain Press (1988). In addition to the color saturation, the color shift is an important feature in the characterization of CN films compared to the respective standard color tables. A low number in Table 2 means that the deviation from the original is small is and the film can be assessed particularly cheap.
