摘要：
Color photographic silver halide elements, such as color films, can be rapidly fixed using a fixing composition containing a thiosulfate fixing agent, and certain 1,3-thiazolidine-2-thiones. 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 (less than 60 seconds), the fixing composition also minimizes residual dye stain from sensitizing dye aggregates within the photographic elements.
