Definitions

  • the invention relates to a silver halide color photographic material which is hardened with an instant hardener and shows no decrease in sensitivity and no increase in fog even in moist storage.
  • the layers need to be hardened for the production of photographic materials.
  • the following methods are known for hardening:
  • the quick hardening process also uses additives eg vinyl sulfones that are added to the casting solutions.
  • additives eg vinyl sulfones that are added to the casting solutions.
  • the hardening of the layer composite is completed after a few hours, which is fundamentally advantageous, but there are very high demands on the course of drying and on the residual moisture of the products, since otherwise the product quality will deteriorate due to post-curing.
  • the instant hardening process offers a number of advantages over this process. However, it has been shown that some photographic materials hardened in this way suffer a slight loss of sensitivity and a certain increase in fog when stored, particularly in a moist environment.
  • Immediate hardeners are understood to mean compounds which crosslink suitable binders in such a way that the hardening is completed immediately after casting or at the latest after 24 hours, preferably after 8 hours, to the extent that no further change in the sensitometry caused by the crosslinking reaction and the swelling of the layer structure occurs. Swelling is the difference between the wet film and dry film thickness understood in the aqueous processing of the film (Photogr. Sci. Eng. 8 (1964), 275; Photogr. Sci. Eng. 16 (1972), 449). For photographic materials containing immediate hardness, mercury compounds are generally recommended as stabilizers in EP-A-21 108.
  • the object of the invention was to prevent or at least reduce the increase in fog and loss of sensitivity in such materials.
  • the invention therefore relates to a color photographic silver halide material with at least one blue-sensitive, a yellow dye-producing, at least one green-sensitive, a purple, dye-producing and at least one red-sensitive, blue-green dye-producing silver halide emulsion layer arranged on a support and hardened with an instant hardening agent characterized in that it contains a mercury (II) compound in at least one blue-sensitive silver halide emulsion layer or an adjacent light-insensitive layer, and the blue-sensitive layer is closer to the support than all other color-sensitive layers.
  • an instant hardening agent characterized in that it contains a mercury (II) compound in at least one blue-sensitive silver halide emulsion layer or an adjacent light-insensitive layer, and the blue-sensitive layer is closer to the support than all other color-sensitive layers.
  • the measure according to the invention has a particularly effective effect on color photographic negative paper.
  • the mercury (II) compound e.g. HgCl2 or Hg (CN) 2, is preferably added in an amount of 10 ⁇ 6 to 10 ⁇ 4 mmol / m2 of silver halide material.
  • alkyl is in particular C1-C2 Hydrox-alkyl optionally substituted by halogen, hydroxy, sulfo, C1-C20-alkoxy.
  • Aryl unless otherwise defined, is in particular optionally substituted by halogen, sulfo, C1-C20-alkoxy or C1-C20-alkyl C6-C14-aryl.
  • Aralkyl unless otherwise defined, is especially C Maschinen-C20-aralkyl substituted by halogen, C1-C20-alkoxy, sulfo or C1-C20-alkyl.
  • Alkoxy unless otherwise defined, is in particular C1-C20 alkoxy.
  • X ⁇ is preferably a halide ion such as Cl ⁇ , Br ⁇ or BF4 ⁇ , NO3 ⁇ , (SO4 2 ⁇ ) 1/2 , ClO4 ⁇ , CH3OSO3 ⁇ , PF6 ⁇ , CF3SO3 ⁇ .
  • Alkenyl is especially C2-C20 alkenyl.
  • Alkylene is especially C2-C20 alkylene; Arylene in particular phenylene, aralkylene in particular benzylene and alkaralkylene in particular xylylene.
  • Suitable N-containing ring systems that can represent Z are shown on pages 16 and 17.
  • the pyridine ring is preferred.
  • R36 and R37 together with the nitrogen atom to which they are attached, in particular form a pyrrolidine or piperidine ring bonded by 2 oxo groups in the o- and o ⁇ -position, which may be benzo, cyclohexeno- or [2.2.1] -bicyclohexenocondensed.
  • Acyl is especially C1-C10 alkylcarbonyl or benzoyl; Carbalkoxy is especially C1-C10 alkoxycarbonyl; Carbamoyl is especially mono- or di-C1-C4 alkylaminocarbonyl; Carbaroxy is especially phenoxycarbonyl.
  • Groups R24 which can be split off by nucleophilic agents are, for example, halogen atoms, C1-C15 alkylsulfonyloxy groups, C7-C15 aralkylsulfonyloxy groups, C6-C15 arylsulfonyloxy groups and 1-pyridinyl radicals.
  • the compounds can be prepared in a simple manner known from the literature.
  • the secondary amines are e.g. with phosgene, the carbamic acid chlorides, which are then reacted with aromatic, heterocyclic nitrogen-containing compounds in the absence of light.
  • the preparation of compound 3 is described in Chemical Reports 40, (1907), page 1831. Further information on the synthesis can be found in DE-OS 2 225 230, DE-OS 2 317 677 and DE-OS 2 439 551.
  • JP-OS ⁇ en 44 140/82 and 46 538/82 and JP-PS 50 669/83 Methods for the synthesis of these compounds are described in more detail in JP-OS ⁇ en 44 140/82 and 46 538/82 and JP-PS 50 669/83.
  • the binder to be cured used in the layers which are subjected to the curing process according to the invention is a proteinaceous binder which contains free amino groups and free carboxyl groups.
  • Gelatin is a preferred example. Gelatin is mainly used in photographic recording materials as a binder for the light-sensitive substances, the coloring compounds and, if appropriate, other additives. Such recording materials often have a large number of different layers.
  • the hardening by means of an instant hardening agent is usually carried out in such a way that the hardening agent is applied in excess as the last layer on the layers to be hardened, it being possible to add further substances, such as UV absorbers, antistatic agents, matting agents and polymeric organic particles, to the hardening coating solution.
  • the timing of the addition is not critical. If the mercury (II) compound is added to a light-sensitive emulsion layer, it is advisable to add at least a part to the ripening optimum. One can also proceed in such a way that part of the Hg (II) amount of a light-insensitive layer, part of a light-sensitive layer at the beginning of ripening and part of the ripening optimum is added. The time of the optimum ripening is known to the person skilled in the art.
  • Sample 1 The material thus obtained was referred to as Sample 1 (comparison).
  • Another material was produced in an analogous manner, with the difference that 3.5 mg HgCl2 per kg AgNO3 were added to the blue-sensitive emulsion before the chemical ripening (sample 2).
  • Samples 1-4 were exposed both fresh and after 3 months' storage at room temperature and color developed.
  • a material was produced as in Example 1.
  • the blue-sensitive silver bromide chloride emulsion 0 or 1.5 mg HgCl2 per kg AgNO3 were added before the start of ripening. After reaching the optimum ripeness, the following amounts were added: 0 mg sample 2 1.0 mg sample 3 1.5 mg sample 4 3.9 mg sample 5
  • sample 1 According to the information in Example 1, sample 1, further materials were produced (samples 1 to 3), which differed as follows:
  • the material differs from sample 1 in that 0.002 or 0.012 mg Hg (CN) 2 were embedded in the intermediate layer described in sample 1.
