Definitions

  • the invention relates to a method for processing an exposed, color-photographic, light-sensitive silver halide material by developing, bleach-fixing, washing or stabilizing and drying, the use of compounds coupling to colorless reaction products in the bleach-fixing solution to prevent the precipitation of poorly soluble residues.
  • the developer solution used in the process according to the invention is free of benzyl alcohol; the pH value of the bleach-fix solution, which contains certain bleach accelerators, is ⁇ 7.
  • the basic stages of processing color photosensitive materials generally include a color development stage and a silver removal stage. At Reversal materials are followed by an upstream black / white development and a second exposure.
  • the silver produced during development is oxidized with a bleaching agent and dissolved with a fixing agent.
  • the removal of the silver can be carried out in two stages with a bleaching bath and a fixing bath or in one stage with a bleach-fixing bath.
  • the bleaching process is predominantly carried out using an iron (III) ion complex salt (for example aminopolycarboxylic acid iron (III) complex salt, in particular iron (III) ethylene diamine tetraacetate complex salt).

  • Iodoso compounds, persulfates, cobalt (III) ion complex salts and cerium IV ion complex salts are also suitable.
  • iron (III) ion complex salts have a comparatively low oxidizing power. There was therefore a need to increase the bleaching power of the bleach-fixing solution containing an iron (III) ion complex salt as a bleaching agent.
  • bleach accelerators examples include thiourea derivatives (JP-OS 8506/70, US Pat. No. 3,706,561), selenourea derivatives (JP-OS 280/71), mercapto compounds with a five-membered ring (GB-PS 1 138 842), thiazole derivatives and thiadiazole derivatives ( CH-PS 336 257).
  • EP-A-0 270 217 describes a processing method in which the developer solution is free of benzyl alcohol and the pH of the bleach-fixing solution, which contains an iron (III) complex salt and a bleach accelerator, is between 3 and 6.8.
