  • Scratch resistant layer containing electronically conductive polymer for imaging elements
    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.
    Type: Grant
