Patent number: 6521384Abstract: The present invention is directed to a photothermographic element in which the density formed in a thermally processed photothermographic element is limited for the purpose of scanning the element prior to removal of silver halide, metallic silver, and/or any organic silver salts. In one embodiment of the invention, this is accomplished by employing limited quantities of sensitized silver halide in a photothermographic element.Type: GrantFiled: May 14, 2001Date of Patent: February 18, 2003Assignee: Eastman Kodak CompanyInventor: Richard P. Szajewski

Patent number: 6506528Abstract: This invention relates to a photothermographic color element containing a mixture of blocked developers in the same emulsion layer, which blocked developers having different onset temperatures. Such a mixture has been found to allow for lower film processing temperatures and/or shorter times of development with respect to the blocked developer having a higher onset temperature. Conversely, improved discrimination can be obtained with respect to the blocked developer having the lower onset temperature.Type: GrantFiled: November 20, 2000Date of Patent: January 14, 2003Assignee: Eastman Kodak CompanyInventors: Zbyslaw R. Owczarczyk, David T. Southby, Xiqiang Yang

Color-developing agent, silver halide photographic light-sensitive material and image-forming method
Patent number: 6495304Abstract: There is disclosed a novel color-developing agent of a 1,2,4-thiadiazol-5-yl hydrazine type. There is also disclosed a silver halide photographic light-sensitive material which gives sufficient color formation by development and forms an image excellent in image quality and image storability, by using the color-developing agent. Further, there is disclosed an image-forming method using the light-sensitive material.Type: GrantFiled: June 25, 2001Date of Patent: December 17, 2002Assignee: Fuji Photo Film Co., Ltd.Inventors: Osamu Uchida, Yasuhiro Ishiwata, Kiyoshi Takeuchi, Taiji Katsumata, Takashi Nakamura -
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.
