ABSTRACT:
A method is disclosed for washing silver halide photographic emulsions, including desalting and/or concentrating, based on depletion phase separation mechanism, wherein phase separation is effected by the addition of water-soluble non-interactive and non-adsorbing non-ionic polymers or non-ionic surfactant micelles. The process involves the separation of the supernatant fluid, containing the undesirable water-soluble salts and the added phase separating agents, from the washed and condensed silver halide phase and redispersion of the latter.
