Patent number: 6436618Abstract: 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: GrantFiled: May 21, 2001Date of Patent: August 20, 2002Assignee: Eastman Kodak CompanyInventors: Jean M. Buongiorne, Charles M. Darmon, Michael J. Haight, Erika S. McLarney, Barry C. Kocher, Sheridan E. Vincent, Charles S. Christ, Jr.

Patent number: 6312877Abstract: A homogeneous, ready to use, single-part color developing concentrate comprises a color developing agent in free base form, an antioxidant for the color developing agent, a buffering agent, and a water-miscible or water-soluble hydroxy-substituted, straight-chain organic solvent present in an a concentration such that the weight ratio of water to the organic solvent is from about 15:85 to about 50:50. In addition the concentrate includes a mixture of a specific polyaminopolyphosphonic acid and either a hydroxyalkylidene-diphosphonic acid or morpholinomethanediphosphonic acid (or salt thereof) for stability in the presence of calcium ions. This concentrate is prepared by mixing the components in a unique order for improved safety and manufacturability. It can be used to make a working strength processing solution, or it can be used as a replenishing composition with proper dilution to provide color images in photographic silver halide materials.Type: GrantFiled: July 21, 2000Date of Patent: November 6, 2001Assignee: Eastman Kodak CompanyInventors: Jean M. Buongiorne, Michael J. Haight

Patent number: 6228567Abstract: A homogeneous color developing concentrate comprises a color developing agent in free base form, an antioxidant for the color developing agent and a water-miscible or water-soluble hydroxy-substituted, straight-chain organic solvent. This concentrate is prepared in a unique manner, namely by combining the noted components and removing the sulfate anions commonly present in color developing agents by precipitation with alkali metal ions. The concentrate can be used to prepare photographic processing concentrates and working strength solutions.Type: GrantFiled: April 7, 2000Date of Patent: May 8, 2001Assignee: Eastman Kodak CompanyInventors: Charles M. Darmon, Jean M. Buongiorne, Michael J. Haight, Paul A. Schwartz

Patent number: 5736302Abstract: A photographic reversal bath concentrate is formulated in such a manner as to avoid precipitates while including new biocides and excluding propionic acid. The concentrate is prepared by adding stannous ion nucleating agent to a solution of an organic phosphonic or phosphinic acid chelating agent, followed by addition of a quaternary ammonium compound as the sole biocide at a concentration of at least about 1 g/l. The quaternary ammonium compound has a molecular weight of from about 175 to about 440.Type: GrantFiled: March 12, 1997Date of Patent: April 7, 1998Assignee: Eastman Kodak CompanyInventors: Jean M.
