Patents by Inventor Stefan Hilgart

Stefan Hilgart 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).

  • Polymers and their use in imageable products and image-forming methods
    Patent number: 6667137
    Abstract: Infra-red absorbing polymers useful in imageable products and the lithographic printing field comprise infra-red absorbing groups carried as pendent groups on a polymer backbone. Certain infra-red absorbing groups may also act to insolublize the polymer in a developer, until it is imagewise exposed to infra-red radiation. The resulting heat renders the polymer soluble in the developer. Imageable products employing the infra-red absorbing polymers may include positive working lithographic printing plates.
    Type: Grant
    Filed: December 30, 2002
    Date of Patent: December 23, 2003
    Assignee: Kodak Polychrome Graphics LLC
    Inventors: Eduard Kottmair, Hans-Horst Glatt, Stefan Hilgart, Paul West
  • Manufacture of masks and electronic parts
    Publication number: 20030190533
    Abstract: Imageable precursors for masks and for electronic parts comprise a polymeric layer applied to a substrate. The layer comprises at least one polymer having infra-red absorbing groups carried as pendent groups on the polymer backbone. Certain infrared absorbing groups may also act to insolubilize the polymer in a developer, until it is imagewise exposed to infra-red radiation. Imagewise application of heat, resulting from imagewise exposure of the precursor to infra-red radiation, renders the polymer layer more soluble in the developer than prior to exposure to the infra-red radiation.
