Patent number: 6455236Abstract: Compositions and methods of making photographic one-part bleach-fix liquid concentrates, packaged in a single unit, wherein the bleaching agent is a polyvalent metal oxidizing agent are described. A thiocyanate salt is added in an amount sufficient to provide one-part bleach-fix liquid concentrates that are homogeneous, remain free of crystallized precipitates for extended periods of time, and that retain effective oxidizing potential during extended periods of storage. Alternatively, the present invention provides for compositions and methods of making stable bleach-fix liquid concentrates, suitable for dilution to working strength solutions, using a polyvalent metal oxidizing bleaching agent, at least one fixing agent, and a source of phosphate ions. Precipitation, which occurs when an iron (III) bleaching agent is reduced by components of the concentrate, is prevented by the addition of thiocyanate and/or phosphate ions.Type: GrantFiled: November 17, 2000Date of Patent: September 24, 2002Assignee: Trebla Chemical CompanyInventor: Laszlo Papai

Patent number: 6440653Abstract: A method of producing a photographic image in an imagewise exposed photographic material comprising one or more silver halide emulsion layers comprises developing the material with a developer solution containing a silver halide developing agent, applying to the surface of the developed material a solution of a sulphite compound that reacts with oxidised developing agent and prevents further development, and applying to the surface of the developed material a solution of an oxidant that oxidises any remaining developing agent, wherein said sulphite compound is present in an amount sufficient to react with all the oxidised developing agent and said solutions of sulphite and oxidant are applied to the material by means other than immersion in a tank.Type: GrantFiled: May 10, 2001Date of Patent: August 27, 2002Assignee: Eastman Kodak CompanyInventors: John R. Fyson, Louis E. Friedrich

Publication number: 20020115027Abstract: A method and system for environmental control in film processing is disclosed. In general, photographic film is coated with a processing solution, such as a developer solution, and is then developed within a controlled air environment. In the preferred embodiments, the temperature and humidity within the air environment is strictly controlled, which allows the development process to be more accurately and consistently controlled. This also allows fewer processing chemicals to be used and reduces harmful effluents caused by photographic film processing.Type: ApplicationFiled: December 31, 2001Publication date: August 22, 2002Inventors: Mark White, Angela Cheng, Paul N. Winberg, Michael Rohrer

Publication number: 20020115028Abstract: An image forming assembly and method utilizes a laminate processing sheet. The laminate processing sheet is applied on an emulsion side of an exposed photosensitive film which includes sprocket holes along opposing edges. In a first feature of the present invention, a width of the laminate processing sheet is confined to an image area between the opposing sprocket holes, so as to reduce or eliminate the possibility of processing marks in or around an area of the opposing sprocket holes In a further feature of the present invention, an absorbing sheet can be applied to the backside of the photosensitive film, to absorb any excess processing or wetting solution that is applied to the photosensitive film. This also aids in reducing or eliminating unwanted processing marks at the sprocket holes or an area in the vicinity of the sprocket holes.Type: ApplicationFiled: March 6, 2002Publication date: August 22, 2002Inventors: Richard P. Szajewski, Wanda K. Swartz

Patent number: 6432623Abstract: A method of processing a photographic imaging element to obtain a protective overcoat is disclosed, which overcoat provides, in the final product, resistance to fingerprints, common stains, and spills. More particularly, the present invention involves a processing-solution-permeable overcoat that becomes water and stain resistant in the photochemically processed product. The overcoat formulation comprises at least one water-dispersible hydrophobic polymer interspersed with a water-soluble polymer. During development or thereafter, before drying, the water-soluble polymer is removed to a significant extent. Subsequently, the imaged element is dried at an elevated temperature to facilitate coalescence of the overcoat to thereby provide enhanced stain resistance and water-resistance.Type: GrantFiled: April 27, 2001Date of Patent: August 13, 2002Assignee: Eastman Kodak CompanyInventors: Kevin M. Donovan, Lloyd A. Lobo

Publication number: 20020102503Abstract: A method for processing a silver halide photographic material comprises the steps of loading the material into a chamber adapted to hold the material therein, introducing a metered amount of a first processing solution into the chamber, processing the photographic material with the first processing solution, introducing a metered amount of a second processing solution which is other than a second part of the first processing solution into the chamber without removing the first processing solution so that at least part of the total volume of the second processing solution is provided by the first processing solution and processing the photographic material with the second processing solution, the total volume of solution for each processing stage being spread over the whole area of the photographic material in a repetitive manner to enable uniform processing.Type: ApplicationFiled: October 30, 2001Publication date: August 1, 2002Applicant: Eastman Kodak CompanyInventor: Peter J.

Patent number: 6426269Abstract: A method, and a system for employing the method, for providing a modified optical proximity correction (OPC) for correcting distortions of pattern lines on a semiconductor circuit wafer. The method comprises producing a mask having one or more pattern regions, and producing the semiconductor circuit wafer from the mask. The pattern regions include one or more non-edge pattern regions located adjacent to other of the non-edge pattern regions on the mask. The pattern regions further include one or more edge pattern regions located at or near an area on the mask not having the other non-edge pattern regions. The edge pattern regions have widths calculated to minimize the variance in dimensions between one or more pattern lines on the semiconductor circuit wafer formed from them and one or more pattern lines on the semiconductor circuit wafer formed from the non-edge pattern regions.Type: GrantFiled: October 21, 1999Date of Patent: July 30, 2002Assignees: International Business Machines Corporation, Infineon Technologies North America Corp.Inventors: Henning Haffner, Heinz Hoenigschmid, Donald J.
