  • Patent number: 6010253
    Abstract: The present invention is a film packet which includes a photosensitive film sheet having leading and trailing ends. A light-shielding envelope removably encloses the carrier sheet and the film sheet. The envelope has first and second exterior surfaces overlying the first and second outward-facing surfaces respectively and has first and second interior surfaces facing the first and second outward surfaces respectively. The envelope includes longitudinally extending leading and trailing end portions overlying the leading and trailing end sections respectively. The leading end portion is sealed closed, and the trailing end portion is closable by cooperative engagement with the light-locking element. The leading end portion includes first and second graspable zones. The first graspable zone overlies the tab so that, when grasped, the first zone is pressed against the tab and the second graspable zone does not overlie the tab so that, when grasped, the second zone is not pressed thereagainst.

  • Patent number: 5932519
    Abstract: A thermal dye transfer assemblage comprising:(I) a dye-donor element comprising a support having thereon a dye layer comprising a dye dispersed in a polymeric binder, the dye being a deprotonated cationic dye which is capable of being reprotonated to a cationic dye having a N-H group which is part of a conjugated system, and(II) a dye-receiving element comprising a support having thereon a polymeric dye image-receiving layer, the dye-receiving element being in a superposed relationship with the dye-donor element so that the dye layer is in contact with the polymeric dye image-receiving layer, the polymeric dye image-receiving layer comprising a mixture ofa) a polymer having a Tg of less than about 19.degree. C. and having no or only slight acidity; andb) sub-micron, non film-forming, organic, acidic particles which are capable of reprotonating the cationic dye transferred to the dye image-receiving layer from the dye layer.

  • Patent number: 5856051
    Abstract: The present invention is an imaged photographic element having a protective overcoat thereon. The protective overcoat formed by the steps of providing a photographic element having at least one silver halide light-sensitive emulsion layer; applying a coating comprising hydrophobic polymer particles having an average size of 0.01 to 1 microns, a melting temperature of from 55.degree. to 200.degree. C. at a weight percent of 30 to 95, and gelatin at a weight percent of 5 to 70 over the at least one silver halide light-sensitive emulsion layer. The silver halide light sensitive emulsion layer is developed to provide an imaged photographic element. The hydrophobic polymer particles are then fused to form a protective overcoat. In an alternate embodiment the coating further includes water soluble polymer materials at a weight percent of from 5 to 45.

  • Patent number: 5807661
    Abstract: The present invention is a photographic element which includes polyester film support and at least one light-sensitive silver halide layer on a front side of the support. An antistatic layer is superposed on the backside of the support. A transparent magnetic recording layer is superposed on the backside of the support. A protective lubricating overcoat layer is superposed on the backside of the support, the antistatic layer being closest to the support and the overcoat layer being furthest from the support. The protective lubricating overcoat layer includes fluorinated ethylene polymer particles having a mean particle size of from 0.01 to 0.5 .mu.m, abrasive particles having a Mohs scale hardness of 6 or more and a median diameter of from 0.1 to 0.4 .mu.m, and a transparent binder.
