Publication number: 20040185390Abstract: Stable, single-part photographic bleach-fixing “precursor” compositions comprise one or more iron-ligand complexes, one or more thiosulfates as the sole fixing agents, and optionally, a sulfite preservative. At least 50 mol % of the iron in the composition is in the form of Fe(II). This composition can be used directly in photoprocessing, or used as a regenerator when mixed with bleach-fixing overflow to provide a replenishing solution. Because the Fe(II) compounds are precursor bleaching agents, they must be oxidized to Fe(III) for active bleaching prior to or during the photographic processing operations.Type: ApplicationFiled: January 28, 2004Publication date: September 23, 2004Inventors: Sheridan E. Vincent, Valerie L. Kuykendall, Jean M. Buongiorne

Patent number: 6582136Abstract: A control tool for monitoring a predetermined process condition in a photographic process and method of making the control tool. The control tool includes a support element having a plurality of rows, each row having a plurality of visual density patches and representing a different process condition. At least one of the rows is used for monitoring a process condition being monitored and at least one of the other of the rows identifies an out-of-control process condition. The plurality of rows of visual density patches are designed to be correlated with a process control strip that has been processed in the photographic process to be monitored, the support element further having textual information identifying at least one process condition and describing the process condition that may need to be corrected in response to correlation of the control strip to the control tool.Type: GrantFiled: February 20, 2002Date of Patent: June 24, 2003Assignee: Eastman Kodak CompanyInventors: Sheridan E. Vincent, Peter VanderBrook, John A. Weldy

Patent number: 6534253Abstract: Photographic bleach-fixing solutions in a processing chamber can be directly replenished using a single-part photographic bleach-fixing “precursor” composition that comprises one or more iron-ligand complexes, one or more thiosulfates as the sole fixing agents, and optionally, a sulfite preservative. At least 50 mol % of the iron in the composition is in the form of Fe(II). Immediately prior to or during directly supplying the precursor composition to the processing chamber from an enclosed container, sufficient ferrous ions are converted to ferric ions to provide desired bleaching in the processing chamber.Type: GrantFiled: November 15, 2001Date of Patent: March 18, 2003Assignee: Eastman Kodak CompanyInventors: Valerie L.

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.

Patent number: 4975357Abstract: Hydroxylamine compounds are commonly included in photographic color developing solutions to retard aerial oxidation. When the photographic element processed in the color developing solution is one which contains an aromatic polyhydroxy compound which serves as a stabilizing addendum, there will be a build-up of the level of such compound in the developing solution as seasoning occurs. Also, as a consequence of seasoning, there is a gradual build-up of the level of trace metal impurities in the solution. Interaction of a trace metal impurity with the aromatic polyhydroxy compound can form a metal-complex which catalyzes the oxidation of the hydroxylamine compound and thereby renders it ineffective for its intended purpose. In the improved method of this invention, the color developing solution is protected against the unwanted metal-complex catalyzed oxidation by incorporation therein of an aminopolycarboxylic acid sequestering agent.Type: GrantFiled: May 23, 1989Date of Patent: December 4, 1990Assignee: Eastman Kodak CompanyInventors: Jean M. Buongiorne, Janet M. Huston, Paul A. Schwartz, Sheridan E. Vincent

Patent number: 4892804Abstract: Photographic color developing compositions which are especially useful in the processing of high chloride silver halide photographic elements are free, or at least substantially free, of bromides; optionally contain a small amount of sulfite; and comprise (1) a primary aromatic amino color developing agent, (2) an N,N-dialkylhydroxylamine, (3) at least one sequestering agent which functions to sequester iron and (4) at least one sequestering agent which functions to sequester calcium. The developing compositions exhibit excellent stability. They also provide minimal development restraint which permits the use of very short development times, as needed for rapid access processing.Type: GrantFiled: August 16, 1988Date of Patent: January 9, 1990Assignee: Eastman Kodak CompanyInventors: Sheridan E. Vincent, Richard W. Berls

Patent number: 4414307Abstract: Sparingly-soluble alcohols, such as benzyl alcohol, which function to enhance photographic coupling efficiency are incorporated in photographic color developing solutions by the use of solid water-soluble alcohol-precursor compounds. The solid precursor compounds, which can be advantageously utilized as components of an all-solid photographic processing kit, comprise a solubilizing group which is cleaved by the alkaline environment of the color developing solution to form the sparingly-soluble alcohol. Examples of such solid precursor compounds which are especially advantageous in the preparation of color developing solutions are the alkali metal monobenzylcarbonates and the alkali metal monobenzylsulfites.Type: GrantFiled: February 24, 1982Date of Patent: November 8, 1983Assignee: Eastman Kodak CompanyInventors: Jon A. Kapecki, Thomas M. Gormel, Sheridan E. Vincent

Patent number: 4264716Abstract: Photographic color developer compositions containing a primary aromatic amino color developing agent and an hydroxylamine are stabilized by incorporating therein a combination of sequestering agents, one of which is an aminopolyphosphonic acid compound and another of which is an aromatic polyhydroxy compound. Decomposition of the hydroxylamine, in the presence of heavy metals such as iron which act to catalyze the decomposition, and resultant formation of ammonia is effectively prevented by the presence in the developer composition of this combination of sequestering agents. Undesirable precipitate formation is also effectively avoided.Type: GrantFiled: September 10, 1979Date of Patent: April 28, 1981Assignee: Eastman Kodak CompanyInventors: Sheridan E. Vincent, Michael D. Purol
