Alex Sergey Lonkin 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).

  • Compositions and processes for preparing color filter elements using alkali metal hydroxides
    Patent number: 8017201
    Abstract: The present invention provides compositions derived from a polycarboxylic acid, a polyhydroxy compound, a dye and a basic crosslinking agent. The compositions can be used to prepare cross-linked films that exhibit low solvent-swell characteristics. The cross-linked films can be used to prepare color filter elements via thermal transfer processes.
    Type: Grant
    Filed: December 6, 2007
    Date of Patent: September 13, 2011
    Assignee: E.I. du Pont de Nemours and Company
    Inventors: Brian Michael Fish, Alex Sergey Lonkin

  • Compositions and processes for preparing color filter elements
    Patent number: 7887989
    Abstract: Provided are compositions derived from a polycarboxylic acid, a copper phthalocyanine complex, and a plasticizer. The compositions can be used to prepare color filter films that exhibit lower lip heights, suitable in color filter elements, for example, in liquid crystal display devices.
