  • Stabilized amplified color developing composition, multi-part kits, and method of use
    Patent number: 6660461
    Abstract: An amplified color developing composition is stabilized with a cyclicaminomethanediphosphonic acid or salt thereof alone of in combination with other stabilizing compounds. This composition also comprises a color developing agent, a redox oxidizing agent (such as hydrogen peroxide), and a hydroxylamine antioxidant for the color developing agent. The amplified color developing composition can be formulated using a two- or three-part processing kit. The composition can be used to provide images in various color photographic silver halide materials such as color photographic papers.
