- the color couplers can be, for example, 6-, 4- and 2-equivalent couplers. Suitable couplers are known, for example, from the publications "Farbkuppler” by W. Pelz in “Mitanderen” from the research laboratories of Agfa, Leverkusen / Kunststoff “, Volume III, page 111 (1961), K. Venkataraman in” The Chemistry of Synthetic Dyes “, Vol. 4, 341 to 387, Academic Press (1971) and TH James," The Theory of the Photographic Process ", 4th Ed., Pp. 353-362, as well as from Research Disclosure No. 17643 of December 1978, Section VII, published by Industrial Opportunities Ltd., Homewell Havant, Hampshire, PO9 1 EF in Great Britain.
- the recording material can also contain DIR compounds and white couplers which do not give any dye when reacted with color developer oxidation products.

- the light-sensitive silver halide emulsions used can contain chloride, bromide and iodide or mixtures thereof as the halide.
- the halide content of at least one layer consists of 0 to 12 mol% AgI, 0 to 50 mol% AgCl and 50 to 100% AgBr, the sum of these proportions being 100% complementary.
- the crystals are predominantly compact, for example cubic or are octahedral or have transitional forms. They can be characterized in that they essentially have a thickness of more than 0.2 ⁇ m.
- the average ratio of diameter to thickness is preferably less than 8: 1, it being true that the diameter of a grain is defined as the diameter of a circle with a circle content corresponding to the projected area of the grain.
- all or individual emulsions can also have essentially tabular silver halide crystals in which the ratio of diameter to thickness is greater than 8: 1.
- the emulsions can be chemically sensitized.
- the usual sensitizers are suitable for chemical sensitization of the silver halide grains.

Koslowsky, Z.Wiss.Phot. 46: 65-72 (1951). It is also possible to sensitize the emulsions with polyalkylene oxide derivatives. Reference is also made to Research Disclosure No. 17 643, section III.
- the emulsions can be optically sensitized in a manner known per se, e.g. with the usual polymethine dyes, such as neutrocyanines, basic or acidic carbocyanines, rhodacyanines, hemicyanines, styryl dyes, oxonols and the like, see F.M. Hamer in "The Cyanine Dyes and related Compounds", (1964), Ullmann's Encyclopedia of Industrial Chemistry, 4th edition. Volume 18, pages 431 ff and Research Disclosure No. 17643, Section IV.

- the commonly used antifoggants and stabilizers can be used.
- Particularly suitable stabilizers are mercapto compounds, for example mercaptoazoles, acetylene derivatives, organic reducing agents and azaindenes, preferably tetra- or penta-azaindenes, in particular those which are substituted by hydroxyl or amino groups.
- Such connections are, for example, in the article by Birr, Z.Wiss.Phot. 47 , 1952), pp. 2-58 and in Research Disclosure No. 17643 given above in Section IV.
- the components of the photographic material can be incorporated using customary, known methods. If the compounds are soluble in water or alkali, they can be added in the form of aqueous solutions, optionally with the addition of water-miscible organic solvents such as ethanol, acetone or dimethylformamide. If they are water or are insoluble in alkali, they can be incorporated into the recording materials in a known manner in dispersed form. For example, a solution of these compounds in a low-boiling organic solvent can be mixed directly with the silver halide emulsion or initially with an aqueous gelatin solution and the organic solvent can then be removed. The dispersion of the respective compound thus obtained can then be mixed with the silver halide emulsion. If necessary, so-called oil formers are also used, generally higher-boiling organic compounds, which include the compounds to be dispersed in the form of oily droplets. Particularly suitable such oil formers are in particular:
- Phosphoric acid esters such as triphenyl phosphate and tricresyl phosphate, phthalic acid esters such as dibutyl phthalate, amides such as dibutyl lauryl amide, ethers such as ethylene glycol monobenzyl ether, ketones such as 2-methylcyclohexanone, esters of aliphatic dibasic acid such as ethyl hexyl adipate, esters of aliphatic naphthyronidyl ether pyrid,
- Polymeric oil formers such as polycondensation products of adipic acid and hexanediol or phthalic acid and hexanediol are also suitable.
- Oil formers containing carboxyl groups can also advantageously be used, e.g. the succinic acid derivatives of at least one carboxyl group of US Pat. Nos. 3,689,271, 3,764,336 and 3,765,897.
- the compounds to be emulsified are preferably first dissolved together with at least one compound of the formula (I), if appropriate in a mixture with an oil former, in an organic auxiliary solvent such as ethanol, ethyl acetate, diethyl carbonate, acetone or mixtures thereof.
- an organic auxiliary solvent such as ethanol, ethyl acetate, diethyl carbonate, acetone or mixtures thereof.
- the oil former is preferably used in an amount of 0.1 to 2 parts by weight per part by weight of the compound to be emulsified.
- the organic solution obtained is emulsified in a hydrophilic colloid by customary methods.

- the layers of the photographic material can be hardened in the usual manner, for example with hardeners of the epoxy type, the heterocyclic ethylene imine and the acryloyl type. Furthermore, it is also possible to harden the layers in accordance with the process of German laid-open specification 2 218 009 in order to obtain color photographic materials which are suitable for high-temperature processing. It is also possible to harden the photographic layers or the color photographic multilayer materials with hardeners of the diazine, triazine or 1,2-dihydroquinoline series or with hardeners of the vinyl sulfone type. Further suitable hardening agents are known from German laid-open documents 2 439 551, 2 225 230, 2 317 672 and from Research Disclosure 17643, section XI given above.
- Development can be carried out in the presence of pH buffers, development inhibitors, anti-fogging agents, water softening complexing agents, preservatives, development accelerators, competitive couplers, fogging agents, auxiliary developer compounds and viscosity modifiers; Reference is made to Research Disclosure 17 544 of December 1978, published by Industrial Opportunities Ltd., Homewell Havant, Hampshire, Great Britain, Section XXI and Ullmanns Encyclopedia of Technical Chemistry, 4th Edition, Volume 18, 1979, in particular pages 451, 452 and 463 to 465.
