  • Patent number: 8187475
    Abstract: A device for isolating a component of a multi-component composition. The device includes a housing, a chamber, and a withdrawal port. The chamber is rotatably mounted within the housing. The chamber includes a chamber base and a sidewall. The side wall extends from the chamber base. At least a portion of the sidewall is defined by a filter that permits passage of a first component of the multi-component composition out of the chamber through the filter and to the housing base. The filter restricts passage of a second component of the multi-component composition through the filter. The withdrawal port extends from a position proximate to the housing base to an exterior of the device. The withdrawal port permits the withdrawal of the first component from the housing base to an exterior of the device.

  • Patent number: 6514677
    Abstract: Photothermographic materials comprise heat-bleachable antihalation compositions in antihalation layers. These compositions comprise a hexaarybiimidazole and one or more infrared radiation absorbing compounds that are represented by the following Structure I: A1—L1—A2  I wherein A1 represents a group derived from a dye base, a heterocyclic group, or an electron-donating aromatic group, A2 represents a group derived from a dye base, a heterocyclic group, a group derived from a dye acid, or an electron-donating aromatic group, and L1 represents a conjugated linking group that maintains electron delocalization between A1 and A2 to provide infrared absorbance. The antihalation composition is typically bleached when subjected to a temperature of at least 90° C. for at least 0.5 seconds.

  • Patent number: 6479228
    Abstract: The present invention can relate to an imaging element including a support, an image-forming layer superposed on the support, and an outermost scratch resistant antistatic layer superposed on the support. The scratch resistant layer may include a polymer having a modulus greater than 100 MPa measured at 20° C., a filler particle with the proviso that the filler particle is not an electronically conductive crystalline metal oxide or a compound oxide thereof, and an electronically conducting polymer. The volume ratio of the polymer to the filler particle may be between 70:30 and 40:60 and the electronically conducting polymer can be present at a weight concentration based on a total dried weight of the scratch resistant layer of between 1 and 10 weight percent.

  • Patent number: 6465165
    Abstract: The present invention is an imaged photographic element having a protective overcoat thereon. The protective overcoat is formed by providing a photographic element having at least one silver halide light-sensitive emulsion layer. A first coating of hydrophobic polymer particles having an average size of 0.01 to 1 microns, a melting temperature of from 55 to 200° C. at a weight percent of 30 to 95, and gelatin at a weight percent of 5 to 70 is applied to form a first layer over the silver halide light-sensitive emulsion layer. A second coating of abrasion resistant particles having an average size of from 0.01 to 1 microns is applied to form a second layer over the first layer. The photographic element is developed to provide an imaged photographic element. The first and second layers are fused to form a protective overcoat.
