Definitions

  • the invention relates to a color photographic negative film with improved sensitivity and good color quality.
  • the object of the invention is to improve the overall sensitivity of a color photographic negative material with the aid of a panchromatically sensitized, neutral gray coupling layer, but at the same time to take suitable measures to prevent deterioration in the color quality or at least to keep it as low as possible.
  • the negative material contains so much DIR coupler that there is an interimage effect (IIE) of ⁇ 10% in the yellow, ⁇ 25% in the purple and ⁇ 15% in the cyan region.
  • IIE interimage effect
  • the invention thus relates to a color photographic negative film with at least one yellow-coupling blue-sensitive, at least one purple-coupling green-sensitive, at least one cyan-coupling red-sensitive silver halide emulsion layer and at least one as the uppermost light-sensitive layer attached panchromatically sensitized black coupling layer, the sensitivity of which is at least 3 DIN greater than the most sensitive blue, green or red sensitive layers, measured as a single layer against white light, as well as other usual filter, separating, protective and auxiliary layers on a transparent substrate, characterized in that the negative film contains so much DIR coupler that there is a IIE of ⁇ 10% in the yellow, ⁇ 25% in the purple and% 15% in the cyan region.
  • the IIE (TH James, The Theory of the Photographic Process, 4th edition, Mc Millan Co. NY (1977) pp. 574 and 614) is measured as a percentage distribution of the color gradation with color separation exposure with light of the corresponding spectral range in relation to that color gradation , which arises when exposed to white light.
  • the DIR coupler is preferably in the lower-sensitive layers.
  • DIR couplers can also be present in the highly sensitive color layer, but the coupling speed of the DIR coupler in the highly sensitive color layer should preferably be 1.5 to 25 times smaller than that of the color couplers of this layer.
  • DIR couplers can also be contained in separation, filter or other auxiliary layers.
  • DIR couplers are preferred whose inhibitors have a "diffusibility" according to EP-OS 101 621 of> 0.4.
  • Preferred DIR couplers correspond to the formula A- (X) 1- (Y) m where A is a coupler residue, X an intermediate link, 1 0, 1 or 2, m 1 or 2 and Y is a radical of the formulas which can be split off with a color developer oxidation product mean what R1 for alkyl, alkoxy, acylamino, halogen, alkoxycarbonyl, thiazolidinylidene amino, aryloxycarbonyl, Acyloxy, carbamoyl, N-alkylcarbamoyl, N, N-dialkylcarbamoyl, nitro, amino, N-arylcarbamoyloxy, sulphamoyl, N-alkylcarbamoyloxy, hydroxy, alkoxycarbonylamino, alkylthio, arylthio, aryl, cyano, alkylsulfonyl or aryloxycarbonylam n 1 or 2, R2 is
  • Alkyl R1 to R4 means in particular unsubstituted or substituted straight-chain, branched or cyclic alkyl, where as substituents halogen, nitro, cyano, aryl, alkoxy, aryloxy, alkoxycarbonyl, aryloxycarbonyl, sulphamoyl, carbamoyl, hydroxy, alkylsulfonyl, arylsulfonyl, alkylthio or arylthio or arylthio come.
  • Aryl R1 to R4 is in particular optionally substituted by alkyl, alkenyl, alkoxy, alkoxycarbonyl, halogen, nitro, amino, sulphamoyl, hydroxy, carbamoyl, aryloxycarbonylamino, alkoxycarbonylamino, acylamino, cyano or ureido.
  • Heterocycles R1 to R4 are in particular 5- or 6-membered rings, which may or may not also be fused, in particular benzo-fused and correspondingly substituted aryl.
  • heterocycles are pyridyl, quinolyl, furyl, benzothiazolyl, oxazolyl, imidazolyl, thiazolyl, triazolyl, benzotriazolyl or oxazinyl.
  • the group -X-Y which releases the inhibitor residue Y after a controlled delay, is first split off under the influence of the developer oxidation product.
  • DIR couplers in which 1 is 0 are particularly preferred.
  • the black-coupling partial layer preferably contains no DIR coupler.
  • the layer that is furthest away from the layer support in the layer structure it is the layer that is furthest away from the layer support in the layer structure.
  • it can also be covered with one or more protective layers and / or auxiliary layers, which can contain very low-sensitive micrate emulsions.
  • a light-insensitive separating layer which contains a white coupler and / or a formaldehyde scavenger is preferably introduced between the black-coupling and the first color-coupling layer.
  • the maximum density of the black-coupling partial layer should in particular be between 0.1 and 1.0, preferably between 0.2 and 0.6.
  • the black partial image can be achieved by mixing yellow, magenta and cyan couplers, using black couplers (e.g. described in DE-OS 2 818 363) or other coupler mixtures.
  • a highly sensitive, solarizing emulsion is used in the panchromatically sensitive, black-coupling layer. This limits the black density portion of the pan-sensitive layer to the low density area in the negative (ie to the high density area in the positive copy).
  • the silver halide grains of the emulsion must have a diameter of at least 0.5 ⁇ and be mixed crystals of different halides, for example Ag (Br, J), Ag (Br, Cl), Ag (Br, J, Cl), so that part of the latent image nuclei in the Expose can also form inside the grain.
  • weak chemical ripening preferably with gold compounds
  • Higher precipitation and ripening temperatures 50-60 ° C
  • the presence of small amounts of NH3 during the precipitation, P H ⁇ 6 and excess Br ⁇ during the coating are also advantageous for achieving solarization.
  • Halogen acceptors such as sulfite, ascorbic acid, nitrite, hydrazides or others must not be present in large quantities during the exposure, since halogen acceptors make solarization difficult.
  • the coloring layers contain in the usual way the color couplers complementary to the main spectral sensitivity, ie the red-sensitive layer cyan couplers, the green-sensitive layer purple couplers and blue-sensitive layer yellow couplers.
  • the couplers can be incorporated into the casting solution of the silver halide emulsion layers or other colloid layers in a known manner.
  • the oil-soluble or hydrophobic couplers can preferably be added to a hydrophilic colloid solution from a solution in a suitable coupler solvent (oil former), if appropriate in the presence of a wetting or dispersing agent.
  • the hydrophilic casting solution can of course contain other conventional additives in addition to the binder.
  • the solution of the coupler need not be directly dispersed in the casting solution for the silver halide emulsion layer or other water permeable layer; Rather, it can also be advantageously first dispersed in an aqueous, non-photosensitive solution of a hydrophilic colloid, whereupon the mixture obtained, after removal of the low-boiling organic solvents used, may be mixed with the coating solution for the photosensitive silver halide emulsion layer or another water-permeable layer before application.
  • the so-called latex couplers are also well suited, for example.
  • Suitable light-sensitive silver halide emulsions are emulsions of silver chloride, silver bromide or mixtures thereof, possibly with a low silver iodide content of up to 10 mol% in one of the commonly used hydrophilic binders.
  • the silver halide grains can be limited by the usual crystallographic areas (100, 111, 110, etc.). You can homosexual or heterodisperse, twinned and / or not twisted, bowl-shaped or platelet-like (T-grains), whereby the pure types or mixtures of individual types can be used.
  • Gelatin is preferably used as a binder for the photographic layers. However, this can be replaced in whole or in part by other natural or synthetic binders.
  • the emulsions can be chemically sensitized in the usual way, and the emulsion layers as well as other non-light-sensitive layers can be hardened in the usual way with known hardening agents.
  • Each of the light-sensitive layers mentioned can consist of a single layer or, in a known manner, for example in the case of the so-called double-layer arrangement, also comprise two or more silver halide emulsion partial layers (DE-C-1 121 470).
  • Red-sensitive silver halide emulsion layers are usually arranged closer to the support than green-sensitive silver halide emulsion layers and these are in turn closer than blue-sensitive layers, a yellow filter layer which is not sensitive to light generally being located between green-sensitive layers and blue-sensitive layers.
  • a layer which is not sensitive to light is generally arranged between layers of different spectral sensitivity, the means for preventing the incorrect diffusion of developer oxidation products.
  • silver halide emulsion layers of the same spectral sensitivity can be directly adjacent to one another or be arranged such that there is a light-sensitive layer with a different spectral sensitivity between them (see, for example, DE-A-1 958 709, DE-A-2 530 645, DE -A-2 622 922).
  • the color couplers can be both conventional 4-equivalent couplers and 2-equivalent couplers in which a smaller amount of silver halide is required to produce the color.
  • 2-equivalent couplers are derived from the 4-equivalent couplers in that they contain a substituent in the coupling site, which is split off during the coupling.
  • the 2-equivalent couplers include both those that are practically colorless and those that have an intense intrinsic color that disappears when the color is coupled or is replaced by the color of the image dye produced. The latter couplers may also be present in the light sensitive silver halide emulsion layers.
  • the material according to the invention it is particularly advantageous to use such mask couplers in a somewhat larger amount than is necessary to compensate for the secondary color densities of the image dyes, because a larger IIE can be achieved with a larger mask effect.
  • the white couplers described above are also included in the 2-equivalent couplers, but they do not give any dye when reacted with color developer oxidation products.
  • the 2-equivalent couplers also include the DIR couplers described above, in which it is couplers that contain a removable residue in the coupling site, which is released as a diffusing development inhibitor when reacted with color developer oxidation products.
  • Other photographically active compounds, for example development acefors or fogging agents can also be released from such couplers during development.
  • Couplers which release development accelerators or fogging agents during color development are particularly advantageous if they are only added to the panchromatically sensitized layer in order to increase the sensitivity.
  • the color photographic recording material of the present invention can contain further additives, for example antioxidants, dye-stabilizing agents and agents for influencing the mechanical and electrostatic properties.
  • further additives for example antioxidants, dye-stabilizing agents and agents for influencing the mechanical and electrostatic properties.
  • UV-absorbing compounds in one or more of the layers contained in the recording material, preferably in one of the upper layers use. Suitable UV absorbers are described for example in US-A-3 253 921, DE-C-2 036 719 and EP-A-0 057 160.
  • protective agents for example formaldehyde scavengers or scavengers such as white couplers or hydroquinone derivatives, may be present in formaldehyde and other harmful gases.
  • the color photographic recording material according to the invention is developed with a color developer compound.
  • All developer compounds which have the ability to react in the form of their oxidation product with color couplers to form azomethine dyes can be used as the color developer compound.
  • Suitable color developer compounds are aromatic compounds of the p-phenylenediamine type containing at least one primary amino group, for example N, N-dialkyl-p-phenylenediamines, such as N, N-diethyl-p-phenylenediamine, 1- (N-ethyl-N-methylsulfonamidoethyl) -3 -methyl-p-phenylenediamine, 1- (N-ethyl-N-hydroxyethyl-3-methyl-p-phenylenediamine and 1- (N-ethyl-N-methoxyethyl) -3-methyl-p-phenylenediamine.
