Total hydrophilic colloid per side and the distribution of silver between the emulsion layers is controlled to allow processing in less than 45 seconds while avoiding wet pressure sensitivity.Type: GrantFiled: August 14, 1997Date of Patent: October 20, 1998Assignee: Eastman Kodak CompanyInventor: Robert E.

Patent number: 5723263Abstract: A multicolor negative photographic element comprises a support bearing a blue light-sensitive silver halide emulsion first layer and a green light-sensitized silver halide emulsion second layer wherein said second layer contains a dye sensitized to green light and wherein said first layer has associated therewith a hue correction coupler which upon coupling with oxidized developer produces a dye having a maximum absorbance in the range of 460 to 510 nm. so that the element has a D480/D440 density ratio which is greater than that exhibited by the element without the hue correction coupler. The invention also encompasses a blue sensitive silver halide emulsion layer associated with the hue correction coupler and a method of forming an image in the photographic element of the invention.Type: GrantFiled: November 12, 1996Date of Patent: March 3, 1998Assignee: Eastman Kodak CompanyInventors: Stephen Paul Singer, Paul Barrett Merkel, Jeffrey Walter Schmoeger

Patent number: 5705327Abstract: Color negative photographic films having red, green and blue color sensitive records, wherein the ratio of the toe area contrast to the mid-scale contrast for each of the red, green and blue color records is less than or equal to 0.80, and either at least two color records having a toe-area contrast less than or equal to 0.42 or a mid-scale contrast less than or equal to 0.55, or the film having a speed rating of ISO 200 or greater. The mid-scale contrast for a color record is defined as the slope of a straight line connecting a point C and and a point D on the characteristic curve of Status M density versus log Exposure for the color record, where points C and D are located by defining a point A on the characteristic curve at a density level 0.1 above minimum density, a point B is located on the characteristic curve at an exposure value +1.0 Log Exposure beyond point A, and points C and D are located at exposure values -0.45 log Exposure and +0.45 log Exposure with respect to point B, respectively.Type: GrantFiled: September 16, 1996Date of Patent: January 6, 1998Assignee: Eastman Kodak CompanyInventors: John Charles Brewer, John Tyler Keech, John Frank Sawyer

Patent number: 5582960Abstract: An improved image display material comprising high chloride silver halide emulsions having greater than 90 mole % silver chloride, where the material comprises a yellow dye-forming layer sensitive to blue light comprising a high chloride silver halide emusion with a peak spectral sensitivity to blue light less than about 475 nm, preferably from about 440-475 nm, and a coupler dispersion comprising a yellow dye-forming coupler and a water-insoluble polymer. Photographic image display materials with both short-blue sensitivity and a polymer dispersion in the yellow dye-forming blue-sensitive layer show a synergistic improvement in color reproduction in accordance with the invention, providing for color photographic prints with less color error than seen for materials comprising only one of the components. The improvement is most notable for yellow and green colored areas of a color print.Type: GrantFiled: February 17, 1995Date of Patent: December 10, 1996Assignee: Eastman Kodak CompanyInventors: Ralph B.
