  • Stabilization of silver halide emulsions
    Patent number: 4430426
    Abstract: Silver halide emulsions lack stability in that their properties vary over a period of time. Various stabilizers have been used to reduce the rate and degree of variation. The combination of uracils and nitroso-substituted phenols has been found to provide a synergistic stabilization of speed in silver halide emulsions. Other stabilizers may be combined with those two classes to further improve the stability of the emulsion.
