Pigment Containing Coating Patents (Class 427/218)
  • Patent number: 11787948
    Abstract: Optical effect pigment comprising a plurality of layers and a magnetic element, the layers can be arranged in two stacks of asymmetric layers or in a single stack of layers and comprise at least an absorber layer and at least a dielectric layer and can further comprise a reflector layer. The magnetic element presents a magnetisation which is out-of-plane, i.e. predominantly perpendicular to the plane of the pigment, which allows a deposition on the printing substrate whereby the face of the pigment lying up or down on the substrate can be predetermined. Such effect pigment has applications in many fields and specifically in security printing, where due to controlled deposition for instance a double-stack pigment will produce a different optical effect on each of its faces.

  • Patent number: 8501272
    Abstract: Optically anisotropic spheres that can be used as pixel elements in rotating element displays are fabricated by partially (e.g., hemispherically) coating a plurality of spheres by transfer coating methods. Typically, a monolayer of spaced apart monochromal (e.g., white) spheres is formed on a support surface by, for example, making use of a removable template matrix. Next, a uniform layer of viscous coating material (e.g., black coating) is applied to the monolayer of spheres to transfer at least some of the coating material onto the surface of spheres in a monolayer. The obtained partially coated spheres are optionally cured by a UV or thermal exposure and are then removed from the support substrate. In some embodiments, coating material also provides electrical anisotropy to the spheres. Transfer coating methods result in improved precision of hemispherical coating and allow use of environmentally robust pixel elements.
