Definitions

• 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 preparation of such gelatins is described, for example, in The Science and Technology of Gelatine, edited by AG Ward and A. Courts, Academic Press 1977, page 295 ff.
• the gelatin used in each case should contain as little as possible of photographically active impurities (inert gelatin). High viscosity, low swelling gelatins are particularly advantageous.
• the gelatin can be partially or completely oxidized.
• 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 or benzothiazolium salts can also be used as antifoggants.
• 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.).
• 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, purple couplers of the formula (I) or (II) being used according to the invention exclusively or as a mixture with other purple couplers described below.
• the compounds can also be introduced into the casting solution in the form of loaded latices.
• Suitable oil formers for other couplers and other compounds are e.g. Alkyl phthalates, phosphoric acid esters, citric acid esters, benzoic acid esters, alkylamides, fatty acid esters and trimesic acid esters.
• 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.
• Sub-layers The same spectral sensitization can be adjacent to one another or separated by other layers, for example by layers of different spectral sensitization. For example, 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).
• 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 diffusibility D f is determined for the purposes of the present invention according to the following rule:
• test material B was also produced in the same way, but with the change compared to test material A that layer 2 is composed 0.346 g white coupler and 0.900 g gelatin.
• the DIR compounds to be used according to the invention correspond in particular to the formula A - (L) n - B wherein A the remainder of a compound which, when reacted with the oxidation product of the color developer, releases the group - (L) n -B, in particular the remainder of a coupler, which releases the remainder - (L) n -B when coupled, B the rest of a development inhibitor released from the group - (L) n -B, L is a divalent link which, after loosening the bond AL, is able to loosen the bond LB and n is 0 or 1.
• Preferred groups -LB correspond to the formulas: wherein k 1 or 2 l 0.1 or 2, R26 is hydrogen, alkyl, aryl, hetaryl, halogen, nitro, cyano, alkylthio, acylamino, sulfamoyl, alkoxycarbonylamino or amino, R27 is hydrogen, alkyl, aryl or aralkyl, R28 is hydrogen, halogen, alkyl, aralkyl, alkoxy, anilino, acylamino, ureido, cyan, sulfonamido, aryl or carboxy, R29 is hydrogen, alkyl, aralkyl, cycloalkyl or aryl, M -O- or R30 alkyl, aralkyl, aryl, acyl, hetaryl, acylamino, -OR33 or -PO (OR33) 2 R33 alkyl, aryl or he
• Suitable color developer substances for the material according to the invention are in particular those of the p-phenylenediamine type, e.g. B. 4-amino-N, N-diethyl-aniline hydrochloride; 4-amino-3-methyl-N-ethyl-N- ⁇ - (methanesulfonamido) ethylaniline sulfate hydrate; 4-amino-3-methyl-N-ethyl-N-ß-hydroxyethyl aniline sulfate; 4-amino-N-ethyl-N- (2-methoxyethyl) -m-toluidine-di-p-toluenesulfonic acid and N-ethyl-N-ß-hydroxyethyl-p-phenylenediamine. Further useful color developers are described, for example, in J. Amer. Chem. Soc. 73 , 3100 (1951) and in G. Haist, Modern Photographic Processing, 1979

• the emulsion was ripened at 58 ° C. with 28 ⁇ mol sodium thiosulfate / mol Ag, 8.4 ⁇ mol tetrachloroauric acid / mol Ag and 635 ⁇ mol ammonium thiocyanate / mol Ag to maximum sensitivity.
