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 carboxyl polymers. 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 for desalting and redispersion of the latter.
