Patents by Inventor Lee Korionoff

Lee Korionoff has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Antihalation dye for negative-working printing plates
    Patent number: 6960419
    Abstract: Negative working imageable compositions and imageable elements comprising a layer of the imageable composition over a support are disclosed. The imageable compositions comprise a free-radical polymerizable system and an effective amount of curcumin. The curcumin is effective as an antihalation agent, but does not substantially reduce the photospeed of the imageable composition.
    Type: Grant
    Filed: December 12, 2003
    Date of Patent: November 1, 2005
    Assignee: Kodak Polychrome Graphics LLC
    Inventors: Paul R. West, Lee Korionoff
  • Thermally imageable elements imageable at several wavelengths
    Patent number: 6908726
    Abstract: Infrared absorbing compounds that absorb at 800 nm±50 nm and at 1050 nm±50 nm, the two different regions of the infrared spectrum typically used for imaging, are disclosed. Thermally imageable elements that comprise these infrared absorbing compounds can be imaged with radiation in either of these two regions of the infrared spectrum. The elements are especially useful as lithographic printing plate precursors.
