Definitions

  • the invention relates to a color photographic recording material with at least one more sensitive silver halide emulsion layer and a comparatively less sensitive silver halide emulsion layer, but which are sensitive in the same spectral range, color layers and DIR compounds being assigned to these layers.
  • the invention further relates to a method for developing an exposed photographic recording material.
  • DIR couplers known from GB-A-953454, which carry a substituent in the coupling site which is split off during the coupling with the liberation of a diffusing compound which inhibits the development of the silver halide.
  • DIR compounds are stronger and in less sensitive sub-layers is also specified in DE-A-2600524 and US-A-4170479. From DE-A-2707489 and US-A-4183752 photographic recording materials with DIR compounds of low reactivity are known, which are particularly suitable for blending with more reactive DIR compounds. You can combine a coarse-grained, highly sensitive layer with a color coupler deficit with a less sensitive layer in a so-called double-layer structure. To achieve better sensitometric properties, the DIR compounds can either be added to one of the two layers or to each of the layers, but addition to the lower fine-grained layer of a double-layer structure is preferred.
  • DIR compounds of particularly high reactivity are known from DE-A-2853362 and US-A-4315040.
  • DIR compounds are preferably contained in less sensitive partial layers of a double-layer structure.
  • EP-A-0086654 a DIR connection with a “timing group” is introduced into a highly sensitive layer and a DIR connection without a “timing group” is introduced into a less sensitive layer.
  • the object of the invention is to improve the sensitometric properties of color recording materials.
  • the color granularity of such recording materials should also be improved in the range of low color density without impairing the sensitivity.
  • a photographic recording material with at least one comparatively more sensitive silver halide emulsion layer I and one comparatively less sensitive silver halide emulsion layer 11, both of which are sensitive in the same spectral range, has now been found, layers I and II being assigned DIR compounds of different reactivity and color couplers.
  • layers I and II being assigned DIR compounds of different reactivity and color couplers.
  • the ratio k Ku / k DIR of the effective reaction rate constants of the color coupler K KU and the DIR compound k ⁇ f in layer I is greater than in layer II.
  • the effective reaction rate constants relate to the reaction with the developer oxidation product. This is formed by oxidation of the p-phenylenediamines commonly used as color developer substances by silver halide.
  • reaction rate constants The measurement of reaction rate constants is described, for example, by J. Eggers in “Messages from the Agfa Research Laboratories”, Leverkusen / Kunststoff, Volume III, 1961, pages 81ff. Since it has been shown that the reaction rate constant of a DIR compound is influenced by the surrounding medium, the effective one is according to the invention Response rate constant raised. This takes into account the type of the surrounding medium, for example the use of an oil generator.
  • the effective reaction rate constant can be determined electrochemically by the method known from DE-A-2853362 and US-A-4315070. Then the effective reaction rate constant k eff has the dimension [1 x mol -1 x sek. -1 ].
  • the ratio of the effective reaction rate constants in the more sensitive layer I is preferably between 2: 1 and 20: 1, and the ratio of the reaction rate constants of color coupler and DIR compounds of the less sensitive layer II is preferably between 0.03: 1 and 6: 1.
  • DIR compounds and couplers are each assigned to specific silver halide emulsion layers. Your further reaction in photographic development is therefore controlled by the development of the respective silver halide emulsion layer.
  • color coupler and DIR compound are contained in the respective silver halide emulsion layer itself, but they can also be present in an adjacent layer.
  • the photographic material itself contains the usual color couplers, which can react with the oxidation product of developers, generally p-phenylenediamines, to form dyes.
  • the red-sensitive layer can contain a non-diffusing color coupler for producing the blue-green partial color image, usually a coupler of the phenol or a-naphthol type.
  • the green-sensitive layer can contain, for example, at least one non-diffusing color coupler for producing the purple partial color image, usually color couplers of the 5-pyrazo ion type or of the layer can, for example, contain a non-diffusing color coupler for producing the yellow partial color image, usually a color coupler included with an open chain ketomethylene grouping. In the color couplers it can be, for. B.
  • Couplers are 6-, 4- and 2-equivalent couplers, including the so-called white couplers, which do not give any dye when reacted with color developer oxidation products.
  • Suitable couplers are known, for example, from the publications “Color Couplers” 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, and from Research Disclosure No. 17643 of December 1978, Section VII, published by Industrial Opportunities Ltd., Homewell Havant, Hampshire, P09 1EF in the UK.

  • the released inhibitor substances are preferably mercapto compounds, e.g. B. 1-phenyl-5-mercaptotetrazole.
  • the inhibitory substances are released directly by reaction of the DIR compound with the developer oxidation product.
