ABSTRACT:
Color photographic silver halide elements, such as color films, can be rapidly fixed using a fixing composition containing a mixture of thiosulfate and thiocyanate fixing agents, and certain sulfur-containing 1,2,4-triazoles. Each of the components is present in specific amounts to effect rapid and efficient desilvering. The composition also includes predominantly ammonium cations (at least 50 mol %). Besides effective and rapid silver removal (up to 50 seconds), the fixing composition also minimizes residual dye stain from sensitizing dye aggregates within the photographic elements.
