Patent number: 5567473Abstract: The invention provides photographic paper having increased image stability. The invention is generally accomplished by forming a paper sheet, drying said paper in a first stage to below about 10 percent water, then applying a polyvinyl alcohol solution to both sides of said paper sheet, drying said paper in a second stage to below about 5 percent water, and then applying further polyvinyl alcohol solution to said paper and drying in a third stage. The paper then may be coated to form a silver halide photosensitive color paper. The paper contains between about 4 and about 6 weight percent of polyvinyl alcohol that is concentrated near the surface of said paper. Further, the paper has a oxygen leak rate of less than about 25 cc/m.sup.2 /day and an oxygen GTR rate of less than about 1 cc/m.sup.2 /day.Type: GrantFiled: January 24, 1995Date of Patent: October 22, 1996Assignee: Eastman Kodak CompanyInventors: David J. Lacz, Todd R. Skochdopole, Larry D. Hagemeier, Anita M. Fees, Brian Thomas, Gary J. McSweeney

Patent number: 5212053Abstract: The invention is generally accomplished by forming a translucent display material comprising a substrate and sensitized layers wherein said substrate comprises a paper that has a light transmission rate of greater than 17 percent. It is preferred that the paper have a basis weight of less than 120 grams per square meter that is resin-coated on both sides. The paper of the invention when exposed and developed has a difference between maximum density and minimum density of greater than 2.5. The sensitized layers prior to imaging comprise at least one layer comprising cyan dye-forming coupler, at least one layer comprising magenta dye-forming coupler, and at least one layer comprising yellow dye-forming coupler. In preferred forms, the paper has a basis weight of between 70 and 100 grams per square meter for a balance of translucence and strength. The couplers preferably are present in the following amounts: cyan coupler greater than 0.6 grams per square meter, magenta coupler greater than 0.Type: GrantFiled: February 7, 1992Date of Patent: May 18, 1993Assignee: Eastman Kodak CompanyInventors: Gary J.

Patent number: 4378424Abstract: Mesoionic 1,2,4-triazolium-3-thiolates are silver halide stabilizers and fixing agents. They are useful in heat developable and heat stabilizable photographic silver halide materials and processes. After imagewise exposure of the photographic materials, developed and stabilized silver images are produced by heating the materials. The mesoionic 1,2,4-triazolium-3-thiolates are also silver halide stabilizers and fixing agents in photographic silver halide processing compositions.Type: GrantFiled: November 24, 1981Date of Patent: March 29, 1983Assignee: Eastman Kodak CompanyInventors: Henry W.
