Patent number: 6555309Abstract: In the case where multiple slide hopper is used for simultaneous multilayer bead coating of photosensitive material, streak defect is occasionally cause, particularly in the case of coating photothermographic material, especially when the outermost layer includes materials capable of increasing optical density such as toner it more frequently happens. It is found that streak defect is restrained when meniscus curvature of upper side bead becomes less than 7.2 mm−1. This condition can be kept by selecting a proper value of clearance between the web surface and the lip of the slide hopper, that is from 0.10 mm to 0.40 mm, and a proper value of pressure in a lower side of the bead, that is from −100 Pa to −700 Pa.Type: GrantFiled: December 11, 2001Date of Patent: April 29, 2003Assignee: Fuji Photo Film Co., Ltd.Inventor: Akifumi Kato

Publication number: 20030077546Abstract: The present invention is a photographic element which includes, in order, a transparent support, at least one silver halide emulsion layer superposed on the support, optionally a white or diffuse reflecttive layer, and a processing-solution-permeable protective layer on the backside, which protective layer becomes water-resistant in the final product without lamination or fusing. The present invention is also directed to a method of making a photographic print involving developing the photographic element. The resulting print is viewed through the support, which provides protection against scratches and stains, while the polymeric overcoat provides water and stain protection to the reverse of the print where minor scratches or damage are not critical, since the image is not viewed from this side. Thus, this invention provides for a tough, stain resistant and transparent viewing surface and a stain resistant back side, which is permeable to processing solutions.Type: ApplicationFiled: April 27, 2001Publication date: April 24, 2003Applicant: Eastman Kodak CompanyInventors: Kevin M. Donovan, Glenn M. Brown, Lloyd A. Lobo

Patent number: 6551766Abstract: A process is described for healing scratches on the base side of an imaged motion picture film element comprising a polymeric film base having one or more image layers on one side thereof, the process comprising applying an aqueous coating formulation comprised of an aqueous dispersion of a polyurethane to the scratched base side of the motion picture film element, and drying the applied coating formulation to form a polyurethane layer, wherein the polyurethane comprises an aliphatic polyurethane which has a Young's modulus at 100% elongation to break of less than 4000 psi and a Sward hardness value of at least 60. Scratch healing formulations employed in accordance with the invention provide coated layers with superior resistance to blocking, cleaning solvents, and abrasion, and which are more flexible, dry faster, and are more effective in hiding minor scratches than that disclosed in the prior art.Type: GrantFiled: March 27, 2002Date of Patent: April 22, 2003Assignee: Eastman Kodak CompanyInventors: Thomas M. Smith, Luba Kordovski

Patent number: 6551770Abstract: A heat developable photosensitive material comprising at least two layers is disclosed. The first layer is formed by coating a first coating composition containing the organic silver salt, the photosensitive silver halide, the reducing agent, polymer latex in an amount of at least 30 percent by weight of the first layer at dried state and a solvent, the solvent comprising water in an amount of at least 50 percent by weight of the solvent, and the second layer is formed by coating a second coating composition comprising a polymer latex in an amount of at least 50 percent of the second layer at dried state and a solvent, the solvent comprising water in an amount of at least 60 percent by weight of the solvent, and the second coating composition having a viscosity of from 50 to 1,000 cP at 25 ° C., and the viscosity at 5° C being at least 1.5 times higher than that at 25° C.Type: GrantFiled: June 25, 2001Date of Patent: April 22, 2003Assignee: Konica CorporationInventor: Kazuhiko Hirabayashi
