  • Patent number: 6740145
    Abstract: An effective desiccant for use in a package which has a material including at least in part solid particles of one or more materials, at least one of such materials having an average particle size range 0.001 to 0.1 micrometers to provide a high rate of water absorption and to provide an equilibrium minimum humidity level lower than a humidity level to which a highly moisture sensitive electronic device is sensitive within a sealed enclosure.
    Type: Grant
    Filed: August 8, 2001
    Date of Patent: May 25, 2004
    Assignee: Eastman Kodak Company
    Inventors: Michael L. Boroson, Jeffrey P. Serbicki, Peter G. Bessey, Glen C. Irvin, Lawrence A. Rowley, Cheryl J. Kaminsky
