Patent number: 6929905Abstract: A method of processing a silver bromoiodide photographic element comprising contacting the photographic element with a color developer for less than 120 seconds; wherein the photographic element comprises a support and more than one dye forming unit, and wherein the dye forming unit closest to the support contains an electron transfer agent releasing compound represented by the formula: CAR-(L)n-ETA wherein: CAR is a carrier moiety which is capable of releasing -(L)n-ETA on reaction with oxidized developing agent; L is a divalent linking group, n is 0, 1, or 2; and ETA is a releasable 1-aryl-3-pyrazolidinone electron transfer agent having a calculated log partition coefficient (c log P) greater than or equal to 2.40 bonded to L or CAR through either the nitrogen atom in the 2-position or the oxygen attached to the 3-position of the pyrazolidinone ring.Type: GrantFiled: December 20, 2001Date of Patent: August 16, 2005Assignee: Eastman Kodak CompanyInventors: Stuart T. Gordon, Sharon R. Lunt, David T. Southby, Robert A. Arcus

Publication number: 20020106592Abstract: Disclosed is a color photographic element comprising a multilayered blue light sensitive record, a multilayered green light sensitive record, and a multilayered red light sensitive record, the red record comprising two or more layers of differing light sensitivity, the most light sensitive layer of the red record containing a red light sensitized first emulsion having at least one wavelength of peak absorption, and at least one of the two most light sensitive layers of the red record containing a red sensitized second emulsion, wherein the first emulsion exhibits, as measured at 0.2 density units above Dmin, at least one wavelength of peak absorption that is longer than the shortest wavelength of peak absorption of the second emulsion. The element provides an advantageous combination of speed and color rendition.Type: ApplicationFiled: December 6, 2000Publication date: August 8, 2002Applicant: Eastman Kodak CompanyInventors: Sharon R. Lunt, John F. Sawyer, Mitchell M. Lin
