ABSTRACT:
The present invention relates to methods useful for processing a color photographic material. A method of manufacturing a ferric 1,3-PDTA complex is provided. The method includes reacting ferrous bromide with unchelated 1,3-PDTA, thereby forming a ferrous 1,3-PDTA complex; and conducting an oxidation process wherein the ferrous 1,3-PDTA complex is converted to the ferric 1,3-PDTA complex. Also provided is a method of processing a silver halide color photographic material.
