ABSTRACT:
There is provided a color photograph improved in preservability that has been obtained by making chemically inactive the aromatic amine type color developing agents and their oxidized product that remains in the silver halide photographic materials after color development processing. The color photograph exhibits excellent performance in that its white background can be prevented from discoloring even during long-term storage or display, and deterioration of a dye image caused by the remaining color developing agent being taken into the photographic material after the color development, bleaching, and fixing processes, or due to its oxidized product, can be prevented.
