  • Patent number: 9293739
    Abstract: There is provided a process for forming a contained second layer over a first layer, including the steps: forming the first layer including a fluorinated material and having a first surface energy; treating the first layer with a priming layer; exposing the priming layer patternwise with radiation having a wavelength greater than 300 nm, resulting in exposed areas and unexposed areas; developing the priming layer to effectively remove the priming layer from the unexposed areas resulting in a first layer having a patterned priming layer, wherein the patterned priming layer has a second surface energy that is higher than the first surface energy; and forming the second layer by liquid deposition on the patterned priming layer on the first layer. The priming layer includes an aromatic amine compound and a photoinitiator.

  • Patent number: 5633100
    Abstract: This invention relates to a process for forming a reflection hologram. A process for forming a volume reflection hologram is provided wherein the formation of secondary holograms is suppressed by the placement of index matched filters contiguous to at least one surface of the photosensitive recording element during formation of the hologram.

  • Patent number: 5500311
    Abstract: Holographic flake pigments, processes for making the pigments, decorative coatings comprising the pigments, and articles comprising the decorative coatings are disclosed. The pigment comprises particles that (1) comprise an organic polymer and further comprise one or more volume phase holograms; and (2) have a thickness of about 1 micrometer to about 100 micrometers, an average diameter of about 10 micrometers to about 300 micrometers, and a thickness to diameter ratio of about 1:2 to about 1:60.
