  • the polymers are used in such a way that they enable a limited diffusion of the dye which is formed in the color coupling from the color coupler.
  • Latices that can be loaded are preferably suitable.
  • the polymers described in DE-A 3 036 846, DE-A 1 522 387, DE-A 1 472 746 are particularly suitable.

  • the above-mentioned polymers are added in particular to the highly sensitive partial layers of a color negative material.
  • the highly sensitive sub-layers may contain: color masks, White couplers, scavangers, DIR couplers as well as DAR couplers.
  • a combination of the polymers mentioned here in the highly sensitive partial layers with DIR couplers is particularly advantageous because the sharpness is increased by means of edge effects.
  • a combination of these polymers with DAR couplers (Development Accelerator Release) counteracts grain enlargement.
  • the highly sensitive partial layers can also contain casting aids such as wetting agents and thickeners etc.
  • At least some of the polymers to be used according to the invention are used as carriers for a color coupler.
  • a latex loaded with a coupler there is a latex loaded with a coupler. It can be particularly advantageous to use a mixture of loaded and unloaded latex.
  • the sublayer L can contain the usual constituents, ie in addition to the silver halide emulsion, color couplers, masks, white couplers, scavangers, DIR couplers and / or DAR couplers. These components, in particular the color couplers, can also be applied to a latex in the low-sensitivity layer, which is then present as a loaded latex.

  • additional protective and intermediate layers can be used.
  • Layer structures in which at least one emulsion layer in partial layers of different sensitivity are split are known for example from DE-A 1 958 709 (Pankow).
  • the effective sensitivity When assessing the sensitivity of the individual sub-layers, it is not the absolute sensitivity that is important, but the effective sensitivity, taking into account the respective position within the color photographic multilayer material.
  • the difference in the effective sensitivity is expediently between 0.1 and 1.0 relative log Ixt units. In individual cases, the difference in sensitivity is chosen so that a balanced gradation curve results without perceptible distortion during color photographic processing.
  • auxiliary layers can be present in the color photographic recording material according to the invention, e.g. Adhesive layers, antihalation layers or cover layers, in particular intermediate layers between the light-sensitive layers, as a result of which the diffusion of developer oxidation products from one layer into another is to be effectively prevented.
  • intermediate layers of this type can furthermore contain certain compounds which are able to react with developer oxidation products.
  • Such layers are preferably arranged between adjacent light-sensitive layers of different spectral sensitivity.
  • a less sensitive silver halide emulsion with an average grain diameter of about 0.1 ⁇ m or smaller, which contains chloride, bromide and optionally iodide, can also be embedded in these intermediate layers. Such a layer has a particularly beneficial effect on the sensitivity of the adjacent layers.

  • the blue-sensitive layer can contain, for example, at least one color coupler for producing the yellow partial color image, usually a color coupler with an open-chain ketomethylene grouping.
  • the color couplers can be, for example, 6, 4 and 2 equivalent couplers.
  • Suitable couplers are known, for example, from the publications "Color Coupler” by W. Pelz in "Messages 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.
  • the usual mask couplers can be used to improve the color rendering.
  • 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 inhibitors which can be split off from the DIR compounds can be split off directly or via non-inhibiting intermediate compounds.
  • 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% of AgI, 0 to 50 mol% of AgCl and 50 to 100% of AgBr.
  • the crystals are predominantly compact, e.g. are cubic or 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.

This method of chemical sensitization is described in the article by R. 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.

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.
