  • Multi-part photographic color developing composition and methods of manufacture and use
    Patent number: 6436618
    Abstract: A multi-part color developing kit includes at least two parts (or solutions) of photochemical compositions that can be mixed to provide a color developing composition useful for obtaining color photographic images. A first aqueous solution is formulated with a color developing agent in free base form, an antioxidant for the color developing agent, an inorganic base, a triazinylstilbene optical brightening agent, an chemical base and a water-miscible or water-soluble hydroxy-substituted, straight-chain organic solvent. A second aqueous solution is formulated with a buffering agent, the same or different chemical base and a phosphonic acid metal ion sequestering agent. Both solutions have a pH and homogeneity to provide a clear color developing composition that is safer for use and disposal.
    Type: Grant
    Filed: May 21, 2001
    Date of Patent: August 20, 2002
    Assignee: Eastman Kodak Company
    Inventors: Jean M. Buongiorne, Charles M. Darmon, Michael J. Haight, Erika S. McLarney, Barry C. Kocher, Sheridan E. Vincent, Charles S. Christ, Jr.
