Definitions
- the invention relates to the processing of exposed color photographic materials with at least the steps of color development and bleach fixing with regeneration the processing baths and desilvering of the bleach-fix bath overflow.
- the processing of color photographic materials goes through at least the stages (a) color development, (b) bleaching and (c) fixing, with (b) and (c) fixing for bleaching can be collapsed.
- the Processing baths regenerated, i.e. they are always fed the substances that are consumed by processing.
- the overflow or the pumped processing solution can be rejuvenated because it still contains valuable substances for processing.
- Rejuvenation / recycling means that unwanted substances are removed and necessary used chemicals are supplemented by rejuvenator concentrates.
- the rejuvenate is fed to the overflow of the processing bath after the interfering substances were removed, so that again a suitable Regenerator is created.
- Rejuvenation and regeneration ensure that, firstly, the processing chemicals be better exploited and secondly a smaller attack disposal liquid arises.
- Soluble silver salts accumulate in the bleach-fix bath, caused by overflow or Umpumpung be discharged.
- the overflow is usually caused by Electrolysis desilvered to recover the valuable silver. After that is done Adding the rejuvenator concentrates so that a bleach-fix bath regenerator is produced, that can be reused.
- the bleach-fix bath of the AP94 / RA4 process has a pH of has about 6, on the other hand satisfactory silver electrolysis only at pH values ⁇ 7.4 can be performed, it was previously necessary to Brighten fix bath overflow with alkali to pH ⁇ 7.4 and after desilvering acidify again to at least pH 6.
- the silver electrolysis could therefore only be carried out separately (off-line).
- one with processing would be desirable, in which the bleach-fixer tank filling is desilvered directly (on-line).
- the object of the invention was to avoid the twofold change in the pH value, nevertheless as much silver as possible from the bleach-fix bath remove and regain and desilvering using the processing method operate coupled without affecting the quality of the color photographic Products deteriorate. Because at an elevated pH of 7.5 with a bleach-fix time of 45 s increased amounts of residual silver remain in the material The task is to carry out an online desilvering of the bleach-fixing tank and nonetheless to come to the typical amount of residual silver in the material.
- the bleach-fixing is carried out in two stages with a pH of ⁇ 7.4 in the 1st stage and a pH in the 2nd stage pH value is set to ⁇ 7
- the bleach-fix bath of the 1st stage regenerates and electrolytically desilvered, e.g. constantly between processing tank and electrolysis tank pumped over or from the processing tank via the electrolysis tank and at least another tank (e.g. the regenerator tank) the processing tank is supplied again, the bleach-fixing bath being passed through in the electrolysis tank Electrolysis is desilvered, and the 2nd stage acid to maintain the pH is fed.
- the processing method with an advantageous regeneration process for the bleach-fix bath combined.
- the chemicals to be renewed are the processing bath or a obtained from overflow or pumped over and desilvered bleach-fixing bath Rejuvenate in the form of at least two concentrated different solutions Composition added.
- “Concentrated solutions” means that the processing chemicals in them higher concentration than is the case in the processing bath.
- level 2 (including level / evaporation compensation) 5 ml / m 2 60% by weight acetic acid, so that the pH in the tolerance range from 5.7 to 7 can be maintained in this BX level.
- the BX of the first stage is continuously between the processor's BX tank and pumped around the electrolysis unit (1 to 10 l / minute) and in the electrolysis unit desilvered.
- level 2 (including level / evaporation compensation) 4 ml / m 2 60% by weight acetic acid, so that the pH in the tolerance range from 5.7 to 7 can be maintained in this BX level.
- sensitometric results are typical and correspond to those with a standard standard regeneration can be achieved, with a standard regeneration a single regeneration solution is prepared, all of which are to be regenerated Contains chemicals in a concentration equal to that of the processing bath corresponds to or is slightly higher.
