Definitions
- Color reversal films are processed worldwide according to a standardized process, the E6 process, which consists of the steps Initial development First wash Reverse bath Color development Conditioning bath Bleach bath Fixer Final watering Stabilizing bath Drying exists (communication from Eastman Kodak to processing laboratories in December 1985).
- Hydroquinone sulfonic acid will be the first developer at one pH of 9.7 used.
- the reverse bath, the unexposed Silver halide developable contains at least one tin (II) complex, which is at about pH 5.8 is used.
- the color developer comes with the color developer substance CD 3 applied at pH 12.1.
- the first wash serves the chemical reactions to interrupt after the end of the initial development period and a procrastination by first developers into that To prevent reverse bath.
- the object of the invention was to reduce the photographic Results to create an improvement.
- watering is dispensed with can be, if the subsequent reversal bath in a countercurrent cascade with at least 2 stages, preferably 2 to 4 stages.
- the invention therefore relates to a method for processing photographic Reverse silver halide materials with steps (a) initial development, (b) Reverse, (c) color development, (d) conditioning, (e) bleaching, (f) fixation, (g) optionally watering, (h) stabilizing and (i) drying, characterized in that that no washing was turned on between steps (a) and (b) and step (b) is carried out in countercurrent with at least stages.
- the recommended amount of refill solution not increased. 1100 ml / m2 is recommended Reversal material. Furthermore, the composition of the reversal bath is not changed.
- the reverse bath can also have a pH value and a dilution factor for the concentrate to be adapted to the changed mode of operation and the carry-over rate.
- the final rinsing to which 7.5 l of water / minute is also required according to the standard specification, is dispensed with, and the stabilizing bath is conducted in countercurrent with at least 2 stages, preferably 3 to 5 stages.
- the recommended amount of refill solution of 1100 ml / m 2 is preferably not exceeded.
- the composition of the stabilizing bath also remains unchanged.
- Example 1 The same films as in Example 1 were made according to the invention Process developed, i.e. without Watering after the first developer and with a 2-stage Reverse bath-countercurrent cascade with otherwise with the Standard process matching process data.
- the regeneration rate of the reversal bath was 1.1 l / m 2
- the carryover of the developer into the reversal bath was 70 ml / m 2 .
- the reversal bath contains in the state of use in the first stage 64 ml first developer / l, in the second Level 4.5 ml first developer / l.
