Patent number: 6531273Abstract: This invention involves dispersions comprising ionic liquids and a non-ionic surfactant, optionally further comprising a photographically useful compound such as a dye-forming coupler. Such dispersions form coatings that are relatively free of physical defects, and show reduced problems such as crystallization of components like the couplers or ion pairs.Type: GrantFiled: November 21, 2001Date of Patent: March 11, 2003Assignee: Eastman Kodak CompanyInventors: Leif P.

Patent number: 6517981Abstract: A light-sensitive silver-halide color photothermographic element comprises a typically magenta dye-forming pyrazolone coupler in the cyan record by rendering the hue of the resultant dye a cyan hue. The use of certain para-phenylenediamine developers, for example, containing a substituent group in both the 2- and 6-positions (ortho, ortho') relative to the coupling nitrogen, along with selected magenta dye-forming couplers, when oxidized, yield cyan dyes with certain couplers, resulting in the superior non-hue characteristics of magenta couplers in the cyan layer. By means of the present invention, light sensitive color photothermographic elements can form image dye records of consistent density forming ability and consistent stability in all three color records. Also disclosed is a method of processing such a color photographic element.Type: GrantFiled: August 16, 2001Date of Patent: February 11, 2003Assignee: Eastman Kodak CompanyInventors: Leif P.

Patent number: 6495299Abstract: This invention relates to packaged photographic film that is capable of being alternately processed, according to individual consumer choice, by either (1) a traditional wet-chemistry process with a developer solution followed by desilvering in one or more subsequent solutions to obtain a color negative film, or (2) a dry thermal process without the use of aqueous solutions in which a blocked developing agent located within the photographic element is thermally activated or unblocked, optionally followed by electronic scanning of the developed film without desilvering. This invention enables a single film stock to be developed in both a conventional deep tank process and in a dry thermal process.Type: GrantFiled: May 25, 2001Date of Patent: December 17, 2002Assignee: Eastman Kodak CompanyInventors: David H.

Patent number: 6490023Abstract: A method and apparatus for processing thermal film includes a process sequence that involves a pre-process of a portion of a thermal film to determine optimal conditions for a subsequent process for developing images on the film. In a first feature of the invention, the thermal film undergoes a pre-process for determining the requirements of the subsequent full process of the thermal film. During the pre-process, a portion of the film, preferably before or after an area in which images are captured is used as a process test area. Thereafter, processing during a subsequent processing as well as scanning conditions can be modified based on the optimum processing characteristics determined during the pre-process. In a second feature of the invention, the process sequence can include a pre-process of the entire film and an infrared scanning of the entire film to determine optimal processing conditions for the second process for developing the image.Type: GrantFiled: June 13, 2000Date of Patent: December 3, 2002Assignee: Eastman Kodak CompanyInventors: David H. Levy, Mark E. Irving, James H. Reynolds
