The emulsions also contain 0 to 5 mol% of bromide, iodide and rhodanide, individually or in combination, these halides and pseudohalides being preferably used in particular in the following amounts: 0.01 to 0.5 mol% of iodide, 0.02 to 5 mol% bromide and 0.02 to 5 mol% rhodanide.
  • Compounds capable of forming silver sulfide generally come as sulfur ripening bodies, e.g. Thiosulfate, thiourea, thiosemicarbazide and thiocarbamide, in question.
  • sulfur ripening bodies e.g. Thiosulfate, thiourea, thiosemicarbazide and thiocarbamide, in question.
  • 0.5 to 20 ⁇ g / g Ag are used.
  • Thiosulfate is preferred.
  • R1 and R2 are preferably methyl, R3 is hydrogen.
  • the gold compound used is in particular 0.5 to 20 ⁇ g / g Ag, particularly preferably 1 to 10 ⁇ g / g Ag.
  • the emulsions are iridium-doped, the amount of iridium being 0.01 to 0.5 ⁇ g / g Ag.
  • the emulsion ripened according to the invention shows the desired steep gradation both in the threshold area and in the shoulder area without loss of sensitivity.
  • the silver halide can be predominantly compact crystals which are, for example, regularly cubic or octahedral or can have transitional forms.
  • platelet-shaped crystals can also preferably be present, the average ratio of diameter to thickness of which is preferably less than 8: 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 greater than 8: 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 both homo- and heterodisperse.
  • the emulsions can also contain organic silver salts, e.g. Silver benzotriazolate or silver behenate.
  • Two or more kinds of silver halide emulsions, which are prepared separately, can be used as a mixture.
  • the photographic emulsions can be prepared using various methods (e.g. P. Glafkides, Chimie et Physique Photographique, Paul Montel, Paris (1967), GF Duffin, Photographic Emulsion Chemistry, The Focal Press, London (1966), VL Zelikman et al, Making and Coating Photographic Emulsion, The Focal Press, London (1966) from soluble silver salts and soluble halides.
  • various methods e.g. P. Glafkides, Chimie et Physique Photographique, Paul Montel, Paris (1967), GF Duffin, Photographic Emulsion Chemistry, The Focal Press, London (1966), VL Zelikman et al, Making and Coating Photographic Emulsion, The Focal Press, London (1966) from soluble silver salts and soluble halides.
  • the silver halide is preferably precipitated in the presence of the binder, for example the gelatin, and can be carried out in the acidic, neutral or alkaline pH range, silver halide complexing agents preferably being additionally used.
  • 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 through 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, a fine-grained, so-called Lippmann emulsion preferably being mixed with a less soluble emulsion and being redissolved on the latter.
  • Salts or complexes of metals such as Cd, Zn, Pb, Tl, Bi, Ir, Rh, Fe can also be present during the precipitation and / or physical ripening of the silver halide grains.
  • the precipitation can also be carried out in the presence of sensitizing dyes.
  • Complexing agents and / or dyes can be rendered ineffective at any time, e.g. by changing the pH or by an oxidative treatment.
  • Gelatin is preferably used as the binder. However, this can be replaced in whole or in part by other synthetic, semi-synthetic or naturally occurring polymers.
  • Synthetic gelatin substitutes are, for example, polyvinyl alcohol, poly-N-vinylpyrolidone, polyacrylamides, polyacrylic acid and their derivatives, in particular their copolymers.
  • 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.
  • the binders should have a sufficient amount of functional groups so that enough resistant layers can be produced by reaction 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.
  • the gelatin can be oxidized.
  • 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.
  • the gelatin used in each case should contain the lowest possible level of photographically active impurities (inert gelatin). High viscosity, low swelling gelatins are particularly advantageous.
  • the soluble salts are removed from the emulsion, e.g. by pasta and washing, by flakes and washing, by ultrafiltration or by ion exchangers.
  • 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 e.g. B. von Birr, Z. Wiss. Phot. 47 (1952), pp. 2-58. 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, (subst.) Benzotriazoles can also be used as antifoggants or benzothiazolium salts can be used.
  • metals such as mercury or cadmium, aromatic sulfonic or sulfinic acids such as benzenesulfinic acid, or nitrogen-containing heterocycles such as nitrobenzimidazole, nitroindazole, (subst.)
  • Benzotriazoles can also be used
  • 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
  • these mercaptoazoles also being able to contain a water-solubilizing group, for example a carboxyl group or sulfo group.
  • a water-solubilizing group for example a carboxyl group or sulfo group.
  • 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 light-sensitive material 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 (eg acceleration of development, high contrast, sensitization etc.).
  • the photographic emulsions can be spectral using methine dyes or other dyes be sensitized.
  • 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 bromide.
  • Color photographic materials usually contain at least one red-sensitive, green-sensitive and blue-sensitive emulsion layer. These 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. Usually cyan couplers are assigned to the red-sensitive layers, purple couplers to the green-sensitive layers and yellow couplers to the blue-sensitive layers.
  • Color couplers for generating the blue-green partial color image are usually couplers of the phenol or ⁇ -naphthol type; suitable examples of this are known in the literature.
  • Color couplers for producing the yellow partial color image are generally couplers with an open-chain catomethylene grouping, in particular couplers of the ⁇ -acylacetamide type; Suitable examples are ⁇ -benzoylacetanilide couplers and ⁇ -pivaloylacetanilide couplers, which are also known from the literature.
  • Color couplers for producing the purple partial color image are generally couplers of the 5-pyrazolone, indazolone or pyrazoloazole type; Suitable examples of this are described in large numbers in the literature.
  • 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 site 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), the white couplers that react with Color developer oxidation products result in 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 coupler.
  • DIR, DAR or FAR couplers Since with DIR, DAR or FAR couplers the effectiveness of the residue released during coupling is mainly 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).
  • High molecular weight color couplers are described, for example, in DE-C-1 297 417, DE-A-24 07 569, DE-A-31 48 125, DE-A-32 17 200, DE-A-33 20 079, DE-A-33 24 932, DE-A-33 31 743, DE-A-33 40 376, EP-A-27 284, US-A-4 080 211.
  • 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.
  • oligomers or polymers instead of the high-boiling solvents, oligomers or polymers, so-called polymeric oil formers, can be used.
  • the compounds can also be introduced into the casting solution in the form of loaded latices.
  • anionic water-soluble compounds eg dyes
  • pickling polymers e.g. acrylic acid
  • Suitable oil formers are e.g. Alkyl phthalates, phosphoric acid esters, citric acid esters, benzoic acid esters, alkylamides, fatty acid esters and trimesic acid esters.
  • Color photographic material typically comprises at least one red-sensitive emulsion layer, at least one green-sensitive emulsion layer and at least one blue-sensitive emulsion layer on a support.
  • the order of these layers can be varied as desired. Couplers which form blue-green, purple and yellow dyes are usually incorporated into the red, green or blue-sensitive emulsion layers. However, different combinations can also be used.
  • Each of the photosensitive layers can consist of a single layer or 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 layer 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 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.
  • sub-layers of the same spectral sensitization can differ with regard to their composition, in particular with regard to the type and amount of the silver halide grains.
  • the sublayer with higher sensitivity will be located further from the support than the sublayer with lower sensitivity.
  • Partial layers of the same spectral sensitization can be adjacent to one another or through other layers, e.g. separated by layers of other spectral sensitization.
  • 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).
  • the photographic material may further contain compounds absorbing UV light, whiteners, spacers, filter dyes, formalin scavengers and others.
  • 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).
  • Ultraviolet absorbing couplers such as ⁇ -naphthol type cyan couplers
  • ultraviolet absorbing polymers can also be used. These ultraviolet absorbents can be fixed in a special layer by pickling.
  • Filter dyes suitable for visible light include oxonol dyes, hemioxonol dyes, styrene dyes, merocyanine dyes, cyanine dyes and azo dyes. Of these dyes, oxonol dyes, hemioxonol dyes and merocyanine dyes are used particularly advantageously.
  • Suitable whiteners are described, for example, in Research Disclosure December 1978, page 22 ff, Unit 17 643, Chapter V.
  • binder layers in particular the most distant layer from the support, but also occasionally intermediate layers, especially if they are the most distant layer from the support during manufacture, may contain 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).
  • 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.

  • 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 that react very quickly with gelatin are e.g. to 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 to form peptide bonds and crosslink the gelatin.
