  • Protective overcoats for thermally developable materials
    Patent number: 7622247
    Abstract: Mixtures of an alkyl vinyl ether/maleic anhydride copolymer or an alkylethylene/maleic anhydride copolymer with cellulose acetate provide protective overcoats for thermally developable materials. These protective overcoats exhibit good adhesion to the emulsion layer, are physically hard, and have good optical clarity while maintaining the sensitometric properties of the materials.
    Type: Grant
    Filed: January 14, 2008
    Date of Patent: November 24, 2009
    Assignee: Carestream Health, Inc.
    Inventors: William Donald Ramsden, Chaofeng Zou, Doreen Catherine Lynch, Stacy Marie Ulrich, Sharon Mary Simpson

  • Photothermographic materials containing phosphors and methods of using same
    Patent number: 7074549
    Abstract: Photothermographic materials contain an X-radiation-sensitive phosphor that emits in the range of from about 100 to about 410 nm. The X-radiation-sensitive phosphor is a rare earth phosphate, a yttrium phosphate, a strontium phosphate or a strontium fluoroborate. These photothermographic materials can be provides out of organic solvent or aqueous solvent coating formulations.

  • Photothermographic materials with improved natural age keeping
    Patent number: 7052819
    Abstract: The addition of certain aliphatic and non-aromatic carbocyclic polycarboxylic acids provides an improvement in natural age keeping properties of organic-solvent based photothermographic materials. This improvement is particularly useful in organic-based photothermographic materials containing phosphors in the photothermographic emulsion layer. Phosphor-containing materials can be particularly useful for direct radiographic imaging using X-radiation.
