  • Process for preparing a composite material by vapor depositing a barrier layer on a substrate
    Patent number: 6893679
    Abstract: The invention relates to a composite material and a process for manufacturing the composite material by applying at least a single organic barrier layer to a substrate to reduce the oxygen permeability of the substrate. Depending on the intended application, the composite material may also include an outer cover layer over the barrier layer to improve moisture resistance. The preferred materials are triazines, particularly melamine, that are vapor-deposited onto the substrate to form a thin, durable transparent barrier layer.
    Type: Grant
    Filed: January 14, 2003
    Date of Patent: May 17, 2005
    Assignee: DSM N.V.
    Inventors: Shahab Jahromi, Olav M Aagaard, Jan M Houben, Karel G. H. Raemaekers
