Patent number: 5677116Abstract: The invention provides a photographic element comprising a polyester support bearing a light-sensitive silver halide photographic emulsion layer, the support having adjacent thereto a polymer-containing subbing layer, the subbing layer having adjacent thereto a layer comprising a hydrophilic binder containing dispersed droplets of a high boiling hydrophobic organic liquid, said liquid having a logarithm of its octanol/water partition coefficient (log P) value greater than 7.7. The invention also includes a process for preparing a photographic element of the invention and a process for forming an image in an element of the invention. The invention further includes a photographic element comprising a polyester support bearing a hydrophilic layer containing an antihalation agent, such as elemental silver, with or without an intervening subbing layer.Type: GrantFiled: November 19, 1996Date of Patent: October 14, 1997Assignee: Eastman Kodak CompanyInventors: Paul Leo Zengerle, John Brian Rieger, John William Boettcher, Richard Allen Carmack

Patent number: 5674672Abstract: A continuous silver halide photographic sheet comprises a continuous support which has Young's modulus of 450 to 650 kg/mm.sup.2 in both of its length and width directions and has a knurled area in the form of a belt on each side, at least one subbing layer formed on the support; and at least one silver halide emulsion coated on the subbing layer not only in an area between both knurled areas but also in the knurled areas under the condition that each of the knurled areas has an area in the form of a belt having emulsion coating which has a width of 5 to 95% of the width of the belt of knurled area. Further, a process for preparing the continuous silver halide photographic sheet comprises the steps of forming at least one subbing layer on the support, and coating at least one silver halide emulsion on the subbing layer in the areas described above.Type: GrantFiled: November 28, 1995Date of Patent: October 7, 1997Assignee: Fuji Photo Film Co., Ltd.Inventor: Fumio Kawamoto

Patent number: 5620749Abstract: A process for forming a conductive substrate comprises coating onto a polyethylene terephthalate substrate an aqueous coating solution containing a conductive crosslinkable polymer with charge carrying groups such as sulfonic acid, sulfuric acid ester or quaternary ammonium salt groups attached to a polymerized ethylenic monomer backbone, a volatile amine in an amount to maintain a pH of above 7.0 and a crosslinking agent such as a polyfunctional aziridine, removing water and the volatile amine which decreases the pH to below 7.0 wherein a reaction between the crosslinkable groups of the polymer and the crosslinking agent is initiated to form a crosslinked conductive polymer film.Type: GrantFiled: August 1, 1996Date of Patent: April 15, 1997Assignee: Sterling Diagnostic Imaging, Inc.Inventors: John H. Bayless, Jr., Donald K. Johnes
