  • Naturally occurring gelatin substitutes are, for example, other proteins such as albumin or casein, cellulose, sugar, starch or alginates.
  • Semi-synthetic gelatin substitutes are usually modified natural products.
  • Cellulose derivatives such as hydroxyalkyl cellulose, carboxymethyl cellulose and phthalyl cellulose and gelatin derivatives, which have been obtained by reaction with alkylating or acylating agents or by grafting on polymerizable monomers, are examples of this.
  • the binders should have a sufficient amount of functional groups, so that by reaction enough suitable layers can be produced with suitable hardening agents.
  • functional groups are in particular amino groups, but also carboxyl groups, hydroxyl groups and active methylene groups.
  • the gelatin which is preferably used can be obtained by acidic or alkaline digestion. Oxidized gelatin can also be used. The production of such gelatins is described, for example, in The Science and Technology of Gelatine, published by A.G. Ward and A. Courts, Academic Press 1977, page 295 ff.

  • platelet-shaped crystals can preferably also be present, the average ratio of diameter to thickness of which is preferably at least 5: 1, the diameter of a grain being defined as the diameter of a circle with a circle content corresponding to the projected area of the grain.
  • the layers can also have tabular silver halide crystals in which the ratio of diameter to thickness is substantially greater than 5: 1, for example 12: 1 to 30: 1.
  • the silver halide grains can also have a multi-layered grain structure, in the simplest case with an inner and an outer grain area (core / shell), the halide composition and / or other modifications, such as e.g. Doping of the individual grain areas are different.
  • the average grain size of the emulsions is preferably between 0.2 ⁇ m and 2.0 ⁇ m, the grain size distribution can be either homodisperse or heterodisperse. Homodisperse grain size distribution means that 95% of the grains do not deviate from the mean grain size by more than ⁇ 30%.

  • the latter include, for example, ammonia, thioether, imidazole, ammonium thiocyanate or excess halide.
  • the water-soluble silver salts and the halides are combined either in succession by the single-jet process or simultaneously by the double-jet process or by any combination of the two processes. Dosing with increasing inflow rates is preferred, the "critical" feed rate, at which no new germs are being produced, should not be exceeded.
  • the pAg range can vary within wide limits during the precipitation, preferably the so-called pAg-controlled method is used, in which a certain pAg value is kept constant or a defined pAg profile is traversed during the precipitation.
  • so-called inverse precipitation with an excess of silver ions is also possible.
  • the silver halide crystals can also grow by physical ripening (Ostwald ripening) in the presence of excess halide and / or silver halide complexing agent.
  • the growth of the emulsion grains can even take place predominantly by Ostwald ripening, preferably a fine-grained, so-called Lippmann emulsion, mixed with a less soluble emulsion and redissolved on the latter.

  • Chemical sensitization can be carried out with the addition of compounds of sulfur, selenium, tellurium and / or compounds of the metals of subgroup VIII of the periodic table (for example gold, platinum, palladium, iridium).
  • Thiocyanate compounds, surface-active compounds such as thioethers, heterocyclic compounds can also be used Nitrogen compounds (e.g. imidazoles, azaindenes) or spectral sensitizers (described, for example, by F. Hamer "The Cyanine Dyes and Related Compounds", 1964, or Ullmanns Encyclopedia of Industrial Chemistry, 4th edition, vol. 18, pp. 431 ff. and Research Disclosure No. 17643, Section III).
  • a reduction sensitization can be carried out with the addition of reducing agents (tin-II salts, amines, hydrazine derivatives, aminoboranes, silanes, formamidine sulfinic acid) using hydrogen, by means of low pAg (eg less than 5) and / or high pH (eg above 8) .
  • reducing agents titanium-II salts, amines, hydrazine derivatives, aminoboranes, silanes, formamidine sulfinic acid
  • the photographic emulsions may contain compounds to prevent fogging or to stabilize the photographic function during production, storage or photographic processing.
  • Azaindenes are particularly suitable, preferably tetra- and penta-azaindenes, in particular those which are substituted by hydroxyl or amino groups. Such connections are for example from Birr, Z. Wiss. Phot. 47 (1952), pp. 2-58. Furthermore, salts of metals such as mercury or cadmium, aromatic sulfonic or sulfinic acids such as benzenesulfinic acid, or nitrogen-containing heterocycles such as nitrobenzimidazole, nitroindazole, optionally substituted benzotriazoles or benzothiazolium salts can be used as antifoggants.
  • metals such as mercury or cadmium, aromatic sulfonic or sulfinic acids such as benzenesulfinic acid, or nitrogen-containing heterocycles such as nitrobenzimidazole, nitroindazole, optionally substituted benzotriazoles or benzothiazolium salts can be used as antifoggants.
  • Heterocycles containing mercapto groups for example mercaptobenzthiazoles, mercaptobenzimidazoles, mercaptotetrazoles, mercaptothiadiazoles, mercaptopyrimidines, are particularly suitable, these mercaptoazoles also being able to contain a water-solubilizing group, for example a carboxyl group or sulfo group.
  • mercaptobenzthiazoles for example mercaptobenzthiazoles, mercaptobenzimidazoles, mercaptotetrazoles, mercaptothiadiazoles, mercaptopyrimidines

  • the stabilizers can be added to the silver halide emulsions before, during or after their ripening.
  • the compounds can also be added to other photographic layers which are assigned to a halogen silver layer.
  • the photographic emulsion layers or other hydrophilic colloid layers of the one produced according to the invention can contain surface-active agents for various purposes, such as coating aids, to prevent electrical charging, to improve the sliding properties, to emulsify the dispersion, to prevent adhesion and to improve the photographic characteristics (e.g. development acceleration, high contrast, sensitization, etc.) .

  • the photographic emulsions can be spectrally sensitized using methine dyes or other dyes.
  • Particularly suitable dyes are cyanine dyes, merocyanine dyes and complex merocyanine dyes.
  • Sensitizers can be dispensed with if the intrinsic sensitivity of the silver halide is sufficient for a certain spectral range, for example the blue sensitivity of silver bromides.
  • the differently sensitized emulsion layers are assigned non-diffusing monomeric or polymeric color couplers, which can be located in the same layer or in a layer adjacent to it.
  • the red-sensitive layers become cyan couplers, assigned to the green-sensitive layers of purple couplers and the blue-sensitive layers of yellow couplers.
  • the color couplers can be 4-equivalent couplers, but also 2-equivalent couplers.
  • the latter are derived from the 4-equivalent couplers in that they contain a substituent in the coupling point, which is split off during the coupling.
  • the 2-equivalent couplers include those that are colorless, as well as 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 (mask coupler), and the white couplers that react with color developer oxidation products yield essentially colorless products.
  • the 2-equivalent couplers also include those couplers that contain a cleavable residue in the coupling point, which is released upon reaction with color developer oxidation products and thereby either directly or after one or more further groups have been cleaved from the primarily cleaved residue (eg DE-A-27 03-145, DE-A-28 55 697, DE-A-31 05 026, DE-A-33 19 428), a certain desired photographic activity unfolds, for example as a development inhibitor or accelerator.
  • Examples of such 2-equivalent couplers are the known DIR couplers as well as DAR or. FAR couplers, the latter being able to be added in addition to the compounds according to the invention.
  • white couplers are:
  • DIR couplers which release development inhibitors of the azole type, for example triazoles and benzotriazoles, are described in DE-A-2 414 006, 2 610 546, 2 659 417, 2 754 281, 2 726 180, 3 626 219, 3 630 564, 3 636 824, 3 644 416 and 2 842 063. Further advantages for color reproduction, ie, color separation and color purity, and for detail reproduction, ie, sharpness and granularity, can be achieved with those DIR couplers which, for example, do not split off the development inhibitor directly as a result of the coupling with an oxidized color developer, but only after a further follow-up reaction, which is achieved, for example, with a timing group.
  • DIR couplers which release a development inhibitor which is decomposed into essentially photographically ineffective products in the developer bath are described, for example, in DE-A-32 09 486 and in EP-A-167 168 and 219 713. With this measurement, trouble-free development and processing consistency is achieved.
  • the DIR couplers can be added to a wide variety of layers in a multilayer photographic material, for example also light-insensitive or intermediate layers. However, they are preferably added to the light-sensitive silver halide emulsion layers, the characteristic properties of the silver halide emulsion, for example its iodide content, the structure of the silver halide grains or their grain size distribution having an influence on the photographic properties achieved.
  • the influence of the inhibitors released can be limited, for example, by incorporating an inhibitor scavenger layer in accordance with DE-A-24 31 223. For reasons of reactivity or stability, it may be advantageous to use a DIR coupler which forms in the respective layer in which it is introduced a color which is different from the color to be produced in this layer in the coupling.
  • DAR or FAR couplers can be used, which release a development accelerator or an fogger.
  • Compounds of this type are, for example, in DE-A-2 534 466, 3 209 110, 3 333 355, 3 410 616, 3 429 545, 3 441 823, in EP-A-89 834, 110 511, 118 087, 147 765 and described in US-A-4,628,572 and 4,656,123.
  • DIR couplers examples are:
  • DIR, DAR or FAR couplers mainly the effectiveness of the residue released during coupling is desired and the color-forming properties of these couplers are less important, such DIR, DAR or FAR couplers are also suitable, which give essentially colorless products on coupling (DE-A-1 547 640).
  • the cleavable residue can also be a ballast residue, so that upon reaction with color developer oxidation products coupling products are obtained which are diffusible or at least have a weak or restricted mobility (US Pat. No. 4,420,556).
  • the material may further contain compounds other than couplers, which can liberate, for example, a development inhibitor, a development accelerator, a bleaching accelerator, a developer, a silver halide solvent, a fogging agent or an antifoggant, for example so-called DIR hydroquinones and other compounds as described, for example, in US Pat US-A-4 636 546, 4 345 024, 4 684 604 and in DE-A-3 145 640, 2 515 213, 2 447 079 and in EP-A-198 438.

  • the high molecular weight color couplers are usually produced by polymerizing ethylenically unsaturated monomeric color couplers. However, they can also be obtained by polyaddition or polycondensation.
  • the couplers or other compounds can be incorporated into silver halide emulsion layers by first preparing a solution, a dispersion or an emulsion of the compound in question and then adding it to the casting solution for the layer in question. Choosing the right one Solvents or dispersants depend on the solubility of the compound.
  • Hydrophobic compounds can also be introduced into the casting solution using high-boiling solvents, so-called oil formers. Corresponding methods are described for example in US-A-2 322 027, US-A-2 801 170, US-A-2 801 171 and EP-A-0 043 037.

  • Each of the differently sensitized, light-sensitive layers can consist of a single layer or can also comprise two or more silver halide emulsion partial layers (DE-C-1 121 470).
  • red-sensitive silver halide emulsion layers are often arranged closer to the support than green-sensitive silver halide emulsion layers and these are in turn closer than blue-sensitive layers, a non-light-sensitive yellow filter layer generally being located between green-sensitive layers and blue-sensitive layers.
  • the green or Red-sensitive layers can be selected without the yellow filter layer, other layer arrangements in which e.g. the blue-sensitive, then the red-sensitive and finally the green-sensitive layers follow.
  • the non-light-sensitive intermediate layers which are generally arranged between layers of different spectral sensitivity, can contain agents which prevent an undesired diffusion of developer oxidation products from one light-sensitive layer into another light-sensitive layer with different spectral sensitization.
  • Suitable agents which are also called scavengers or EOP scavengers, are described in Research Disclosure 17.643 / 1978, Chapter VII, 17.842 / 1979, pages 94-97 and 18.716 / 1979, page 650 and in EP-A-60 070, 98 072 , 124 877, 125 522 and in US-A-462 226.

  • Partial layers of the same spectral sensitization can be adjacent to one another or through other layers, for example through Layers of other spectral sensitization must be separated.
  • all highly sensitive and all low-sensitive layers can be combined to form a layer package (DE-A 1 958 709, DE-A 2 530 645, DE-A 2 622 922).

  • Compounds that absorb UV light are intended on the one hand to protect the image dyes from fading by UV-rich daylight and, on the other hand, as filter dyes to absorb the UV light in daylight upon exposure and thus improve the color rendering of a film.
  • Connections of different structures are usually used for the two tasks. Examples are aryl-substituted benzotriazole compounds (US-A 3 533 794), 4-thiazolidone compounds (US-A 3 314 794 and 3 352 681), benzophenone compounds (JP-A 2784/71), cinnamic acid ester compounds (US-A 3 705 805 and 3 707) 375), butadiene compounds (US-A 4 045 229) or benzoxazole compounds (US-A 3 700 455).

  • photographically inert particles of inorganic or organic nature e.g. as a matting agent or as a spacer (DE-A 3 331 542, DE-A 3 424 893, Research Disclosure December 1978, page 22 ff. Unit 17 643, Chapter XVI).
  • the average particle diameter of the spacers is in particular in the range from 0.2 to 10 ⁇ m.
  • the spacers are water-insoluble and can be alkali-insoluble or alkali-soluble, the alkali-soluble ones generally being removed from the photographic material in the alkaline development bath.
  • suitable polymers are polymethyl methacrylate, copolymers of acrylic acid and methyl methacrylate and hydroxypropyl methyl cellulose hexahydrophthalate.
  • Suitable formalin scavengers include H2N-CONH- (CH2) 2-NH-CONH2,
  • Additives to improve dye, coupler and whiteness stability and to reduce the color fog can belong to the following chemical substance classes: hydroquinones, 6-hydroxychromanes, 5-hydroxycoumarans, spirochromanes, spiroindanes, p- Alkoxyphenols, sterically hindered phenols, gallic acid derivatives, methylenedioxybenzenes, aminophenols, sterically hindered amines, derivatives with esterified or etherified phenolic hydroxyl groups, metal complexes.
  • the layers of the photographic material can be hardened with the usual hardening agents.
  • Suitable curing agents include formaldehyde, glutaraldehyde and similar aldehyde compounds, diacetyl, cyclopentadione and similar ketone compounds, bis (2-chloroethylurea), 2-hydroxy-4,6-dichloro-1,3,5-triazine and other compounds, the reactive halogen contain (US-A 3 288 775, US-A-2 732 303, GB-A-974 723 and GB-A 1 167 207) divinyl sulfone compounds, 5-acetyl-1,3-diacryloylhexahydro-1,3,5-triazine and other compounds containing a reactive olefin bond (US-A 3 635 718, US-A-3 232 763 and GB-A 994 869); N-hydroxymethylphthalimide and other N-methylol compounds (US-A 2 732 316 and
  • the hardening can be effected in a known manner by adding the hardening agent to the casting solution for the layer to be hardened, or by overlaying the layer to be hardened with a layer which contains a diffusible hardening agent.
  • Immediate hardeners are understood to mean compounds which crosslink suitable binders in such a way that the hardening is completed to such an extent immediately after casting, at the latest after 24 hours, preferably after 8 hours at the latest, that no further change in the sensitometry caused by the crosslinking reaction and the swelling of the layer structure occurs .
  • Swelling is understood to mean the difference between the wet film thickness and the dry film thickness during the aqueous processing of the film (Photogr. Sci., Eng. 8 (1964), 275; Photogr. Sci. Eng. (1972), 449).
  • hardening agents which react very quickly with gelatin are, for example, carbamoylpyridinium salts which are able to react with free carboxyl groups of the gelatin, so that the latter react with free amino groups of the gelatin with the formation of peptide bonds and crosslinking of the gelatin.
  • Color photographic negative materials are usually processed by developing, bleaching, fixing and washing or by developing, bleaching, fixing and stabilizing without subsequent washing, whereby bleaching and fixing can be combined into one processing step.
  • All developer compounds which have the ability to react in the form of their oxidation product with color couplers to form azomethine or indophenol 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-methanesulfonamidoethyl) -3 -methyl-p-phenylenediamine, 1- (N-ethyl-N-hydroxyethyl) -3-methyl-p-phenylenediamine and 1- (N-ethyl-N-methoxyethyl) -3-methyl-p-phenylenediamine.
  • Other useful color developers are described, for example, in J. Amer. Chem. Soc. 73 , 3106 (1951) and G. Haist, Modern Photographic Processing, 1979, John Wiley and Sons, New York, page 545 ff.
  • bleaching agents e.g. Fe (III) salts and Fe (III) complex salts such as ferricyanides, dichromates, water-soluble cobalt complexes can be used.
  • Iron (III) complexes of aminopolycarboxylic acids are particularly preferred, especially e.g. of ethylenediaminetetraacetic acid, propylenediaminetetraacetic acid, diethyltriaminepentaacetic acid, nitrilotriacetic acid, iminodiacetic acid, N-hydroxyethylethylenediaminetriacetic acid, alkyliminodicarboxylic acids and corresponding phosphonic acids.
  • Persulphates are also suitable as bleaching agents.
  • the bleach-fixing bath or fixing bath is usually followed by washing, which is designed as countercurrent washing or consists of several tanks with their own water supply.
  • the washing can be completely replaced by a stabilizing bath, which is usually carried out in countercurrent.
  • this stabilizing bath also acts as a final bath.
  • the layers were coated with a gelatin protective layer (0.5 ⁇ m dry layer thickness) and with 0.3 g / m2 of the hardening agent hardened.
  • the layer structures A to G and the comparison structure H were produced without the corresponding additives by successively casting the layers 1 to 14 on a transparent layer support.
