Definitions
- EP-A-0 409 019 discloses a color photographic recording material described and claimed with improved color rendering, which thereby is achieved that both the green sensitive and the red sensitive Silver halide emulsion layers by using one or more so-called gap sensitizing dyes an additional sensitization for Light from the gap between the neighboring main spectral ranges green and Get red.
- EP-A-474 193 describes a silver halide color photographic material in which the Sensitivities of the low-, medium- and high-sensitive red-sensitive Emulsion layers at certain wavelengths in fixed ratios to each other stand and in which the red-sensitive emulsion layer of medium sensitivity contains a combination of several sensitizers. It's supposed to be greenish Avoided when taking photographs even under fluorescent lighting conditions become.
- EP-A-575 927 contain the red and green sensitive Silver halide layers are identical in all layers, at 527 nm absorbing sensitizer. The achieved in addition to the sensitivity gain Color rendering improvements are not yet sufficient.
- the invention relates to a color photographic recording material 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 a blue sensitive silver halide emulsion layer with a yellow coupler and optionally further, non-light-sensitive layers, characterized in that that at least one of its red sensitive silver halide emulsion layers and at least one of its green sensitive silver halide emulsion layers in addition to the usual sensitizing dyes, at least one each Contain cyanine dye, which has a maximum absorption in methanolic solution in the range of 517 - 540 nm, 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, each measured in methanolic solution, by at least 1 nm and by are not more than 10
- the additional cyanine dyes mentioned are preferably carbocyanines, the one with at least one of the (two) ring nitrogen atoms Acid-substituted alkyl group.
- Particularly suitable examples of these Cyanine dyes belong to the class of benzimidazole carbocyanines or Substance class of the oxathiacarbocyanines.
- 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 photosensitive silver halide emulsion layer is applied. Suitable as a carrier especially thin films and foils.
- An overview of carrier materials and on the front and back of the auxiliary layers is 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 optionally intermediate layers and protective layers.
- these layers can vary be arranged. This is shown for the most important products:
- Color photographic films such as color negative films and color reversal films show in in the following order on the carrier 2 or 3 sensitive to red, 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.
- the layers are the same spectral sensitivity differ in their photographic sensitivity, the less sensitive sub-layers usually closer to Carriers are arranged than the more sensitive sub-layers.
- a yellow filter layer is applied, which prevents blue light from entering the to get layers below.
- Color photographic paper which is usually much less sensitive to light as a color photographic film, points in the order given below usually a blue-sensitive, yellow-coupling silver halide emulsion layer on the support, a green sensitive, purple coupling silver halide emulsion layer and a red sensitive, cyan-coupling silver halide emulsion layer on; the yellow filter layer can be omitted.
- Deviations in the number and arrangement of the photosensitive layers can occur to achieve certain results. For example, you can all highly sensitive layers in one layer package and all low-sensitive layers Layers to another layer package in a photographic film be summarized to increase the sensitivity (DE 25 30 645).
- Essential components of the photographic emulsion layers are binders, Silver halide grains and color couplers.
- Photographic materials with camera sensitivity usually contain silver bromoiodide emulsions, which may also contain small amounts of silver chloride can contain.
- 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 that from the couplers and the color developer oxidation product Dyes formed are preferably in the following areas: Yellow coupler 430 to 460 nm, purple coupler 540 to 560 nm, cyan coupler 630 up to 700 nm.
- the mostly hydrophobic color coupler, but also other hydrophobic components of the Layers are usually found in high-boiling organic solvents dissolved or dispersed. These solutions or dispersions are then in one emulsified 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.
- emulsified aqueous binder solution usually gelatin solution
- the usually between layers of different spectral sensitivity arranged non-light-sensitive intermediate layers can contain agents which an undesirable diffusion of developer oxidation products from a photosensitive to another photosensitive layer with different prevent spectral sensitization.
- Suitable connections 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, white toners, spacers, filter dyes, formalin scavengers, light stabilizers, antioxidants, D min dyes, additives to improve the stability of dyes, couplers and whites and 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 made by suitable chemical Process networked.
- 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 layer structures 1A to 1F were made a color negative process, which is published 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 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 as a colorimetric description of CN films used. The method is detailed e.g. in R.W.G, Hunt "The
