Definitions
- the invention relates to a color negative film without the otherwise usual yellow filter layer.
- Color photographic recording materials usually contain a transparent support at least one blue sensitive, at least one green sensitive and at least one red sensitive layer.
- color negative films are usually blue-sensitive layers furthest from the substrate remotely located, followed by a yellow filter layer through the processing process is decolorized, and then follow one after the other (looking towards the substrate) green sensitive and red sensitive layers.
- the yellow filter layer is imperative required to the blue sensitivity of the green or red sensitive silver halide emulsion layers push back. This is usually done by one Amount of 0.6-1.2 log units of blue sensitivity.
- a yellow filter dye either colloidal silver is used, which is produced by the bleaching step of the Processing step is removed, or an organic dye in the Filter layer is fixed, but detached from the film by processing e.g. good solubility in water in the alkaline environment of the developer in contrast to the neutral milieu of the layer structure.
- Colloidal silver as a yellow filter dye has two disadvantages: first, the promotion of physical development by silver ions on the silver grains, resulting in the formation of oxidized developer creates a color haze and the durability the film deteriorates when stored in a warm, moist place; and secondly the high one Absorption in spectral ranges other than the desired, which comes at a cost all green sensitivity goes.
- JP-A-63077054 describes a photographic material which a non-diffusing yellow dye in a silver halide emulsion layer (e.g. a green sensitive layer) or another binder layer.
- the object of the invention is to make a color negative film as high as possible Sharpness, good storage stability in warm, humid conditions and good mechanical Get properties.
- the invention relates to a color photographic recording material consisting of a transparent substrate, a red-sensitive silver halide emulsion layer unit, which is assigned at least one colorless cyan coupler, a green-sensitive Silver halide emulsion layer unit which has at least one colorless magenta coupler is assigned to a blue-sensitive silver halide emulsion layer unit, which is assigned to at least one colorless yellow coupler, and possibly further ones, non-light-sensitive layers, the green-sensitive silver halide emulsion layer unit consists of at least two green-sensitive sub-layers, of which the sublayer furthest away from the substrate has the highest sensitivity has and is arranged further away from the layer support than each partial layer the red sensitive silver halide emulsion layer unit and each sub-layer the blue-sensitive silver halide emulsion layer unit from the support is located remotely as the most sensitive sub-layer of the green sensitive Silver halide emulsion layer unit, characterized in that the most sensitive Partial layer of the green-sensitive
- Each of the silver halide emulsion layer units mentioned may consist of at least two silver halide emulsion sub-layers of the same spectral sensitivity, as a rule, the sub-layer with the highest sensitivity from the substrate is arranged farthest away, the recording material in spatial and spectral assignment to each sublayer at least one colorless Contains color coupler.
- the green sensitive silver halide emulsion layer unit from two, three or more green-sensitive silver halide emulsion partial layers, whose most sensitive sublayer is arranged further away from the layer support than all other sub-layers of the green-sensitive silver halide emulsion layer unit and also all sub-layers of the red-sensitive silver halide emulsion layer unit.
- a silver halide emulsion layer unit preferably adjacent to each other; but they can also be subject to the above Specifications by one or more sub-layers of another silver halide emulsion layer unit and, if necessary, non-light-sensitive intermediate layers be separated from each other.
- Spatial assignment is understood to mean that the color coupler is in one such spatial relationship to the relevant sub-layer that there is an interaction possible between them, which is a pictorial agreement between the silver image formed during development and the color image generated from the color coupler allows. This is usually achieved in that the color coupler in the concerned Sub-layer itself is included or in a layer adjacent to this, in which it is a further sublayer of the relevant silver halide emulsion layer unit or optionally an adjacent non-photosensitive binder layer can act. If sub-layers of the same silver halide emulsion layer unit are immediately adjacent to each other, not necessarily each of contain a color coupler.
- Spectral assignment is understood to mean that the spectral sensitivity of the concerned photosensitive silver halide emulsion and the color of the the spatially assigned color coupler generated partial color image in a certain Relation to one another, in the present case the spectral sensitivity each individual color separation (red, green, blue) a complementary color partial color image (Cyan, magenta, yellow) is assigned.
- the green sensitive silver halide emulsion layers thus at least one colorless magenta coupler is assigned.
- a non-light sensitive Binder layer which is used exclusively as a separating layer between the highly sensitive sublayer of the green-sensitive silver halide emulsion layer unit on the one hand and the blue sensitive.
- Silver halide emulsion layer unit on the other hand works.
- Conventional color negative films are located between the im Layer structure top green sensitive and the bottom blue sensitive layer at least one yellow filter layer, i.e. a layer of yellow colloidal silver or one contains yellow organic dye. Such a non-photosensitive yellow filter layer is missing from the color photographic recording material of the present invention.
- any case contains the non-photosensitive separating layer between the most sensitive green-sensitive sub-layer and the lowest blue-sensitive layer no silver halide development nuclei, especially no colloidal silver, and essentially also no organic dye that can be decolorized during processing (yellow filter dye).
- an organic yellow dye that can be decolorized in the process of Substrate most distant, most sensitive sub-layer of the green sensitive Silver halide emulsion layer unit included.
- the acidic residues represented by A 1 and A 2 are to be understood as the residues of open-chain or cyclic CH-acidic ketomethylene compounds.

- dyes of the formulas VI and VII those are again particularly preferred, which have a log P value between 2.0 and 7.0, but preferably between 2.5 and 6.5 exhibit.
- the log P value is the decimal logarithm of the distribution coefficient P a compound in the two-phase system n-octanol / water).
- Yellow filter dyes of the formulas VI and VII are described, for example, in DE 1 96 46 402.
- the escape groups represented by X include those groups whose essential function is to impart the behavior of a 2-equivalent coupler to the magenta coupler, and those groups which, in turn, are able to intervene in development due to their specific reactivity after being split off from the coupler molecule (PUG - photographically useful group ).
- the color photographic recording material according to the invention contains in a conventional manner in addition to the colorless color couplers already mentioned, colored couplers for masking the undesirable secondary color densities of chromogenic development from the color couplers generated image dyes. These are usually yellow magenta couplers and / or yellow or red cyan couplers. It turned out to be advantageous if at least part of or in the color photographic recording material according to the invention contained yellow color coupler in the to the most sensitive sub-layer the green-sensitive silver halide emulsion layer unit on that of Non-light-sensitive binder layer adjacent side facing the substrate is included.
- Suitable yellow couplers which, according to this preferred embodiment of the invention, can be contained in the non-photosensitive binder layer arranged between the green-sensitive and the blue-sensitive silver halide emulsion layer unit correspond to one of the formulas XII and XIII wherein R 34 , R 35 , m and Y have the same meaning as in the formulas X and XI and in which Ar represents an optionally substituted aryl radical.
- the color photographic recording materials according to the invention consist of a transparent substrate on which the various light-sensitive silver halide emulsion layers and non-photosensitive layers are applied.
- a carrier thin films and foils are particularly suitable.
- An overview of carrier materials and auxiliary layers applied to their front and back is in Research Disclosure 37254, Part 1 (1995), p. 285.
- Deviations in the number and arrangement of the light-sensitive layers can be done to achieve certain results. For example can make highly sensitive layers into a layer package and low sensitivity Layers combined into another layer package in a photographic film to increase the sensitivity (DE-A-25 30 645).
- Essential components of the photographic emulsion layers are binders, silver halide grains and color coupler.
- Photographic materials with camera sensitivity usually contain silver bromoiodide emulsions, which may also contain small amounts of silver chloride can.
- the maximum absorption the dyes formed from the couplers and the color developer oxidation product is preferably in the following ranges: yellow coupler 430 to 460 nm, Purple couplers 540 to 560 nm, cyan couplers 630 to 700 nm.
- Color photographic films are used to improve sensitivity, graininess, Sharpness and color separation are often used when reacting with the compounds Developer oxidation product release compounds that are photographically active, e.g. DIR couplers that release a development inhibitor.
- the mostly hydrophobic color coupler, but also other hydrophobic components of the Layers are usually dissolved in high-boiling organic solvents or dispersed. These solutions or dispersions are then in an aqueous Binder solution (usually gelatin solution) emulsifies and lie after drying of the layers as fine droplets (0.05 to 0.8 mm diameter) in the layers in front.
- aqueous Binder solution usually gelatin solution
