Abstract
High silver chloride photographic materials are processed using a development stop bath containing a sulfite fixing agent, followed by bleaching, fixing and treatment with an oxidizing agent that destroys sulfite ions. No washing or stabilizing steps are used after the treatment with oxidizing agent.
Claims11
A method of processing an imagewise exposed photographic silver halide material comprising at least two dye image-forming layer units responsive to different regions of the spectrum in which the silver halide in each layer comprises at least 85 mol % silver chloride, and the layer units contain a dye image-forming color coupler,
- said method comprising, in sequence, the step of dye image formation, followed by the steps:
- (a) treating said material in a bath which stops dye image formation
- (b) bleaching said material in a first bleach bath containing hydrogen peroxide as bleaching agent, or a material that provides hydrogen peroxide, and an alkali metal halide,
- (c) fixing said material in a fixing bath that contains an alkali metal sulfite or a material that provides sulfite as fixing agent, and
- (d) treating said material in a bath containing a colorless oxidizing agent that destroys sulfite ions which bath has a pH of 5 or below, and wherein no washing or stabilizing steps are carried out after step (d).
