摘要:
A method of processing an imagewise exposed silver halide color photographic material is disclosed, wherein the photographic material comprises a support having thereon a photosensitive silver halide emulsion layer containing a silver halide emulsion having a silver chloride content of at least 80 mol %. The processing method comprises the steps of color developing the photographic material in a color developing solution, and then bleach-fixing in a bleach-fixing solution, further comprising replenishing the bleach-fixing solution as the photographic material is processed by adding thereto a regenerated bleach-fixing replenisher and collecting the resulting overflow solution from the bleach-fixing tank, the regenerated bleach-fixing replenisher comprising a regenerating agent and the overflow solution from the bleach-fixing tank, and wherein the solids content of the regenerating agent is at least 70 wt % of the total weight of the regenerating agent. In accordance with the present method, repeated reuse of the used bleach-fixing solution as a replenisher is achieved without adversely affecting the desilvering property and color reproducibility of the processing solution. Processing of a photographic material having a high silver chloride content photosensitive silver halide emulsion layer in accordance with the present method provides excellent photographic images having good storage stability.
