Abstract
A redox amplification process with minimal steps includes processing a silver halide with an amplifier/bleach/fix solution that includes a redox oxidant capable of bleaching a silver image and a fixing agent that does not react with the redox oxidant.
Claims16
A method for processing comprising:
- A) color developing a photographic silver halide color material comprising two or more silver halide layers sensitized to different regions of the visible spectrum having associated therewith appropriate dye image forming couplers, and
- B) treating said color developed material with an amplifier/bleach/fix solution comprising:
- a redox oxidant that is capable of bleaching a silver image,
- a fixing agent that does not poison the catalytic properties of s aid silver image, and that does not react with said redox oxidant, said fixing agent being present in an amount of from 10 to 100 g/l, and
- a fixing accelerator in an amount of from 0.01 to 150 g/l.
