  • Patent number: 10048415
    Abstract: A non-dichroic omnidirectional structural color multilayer structure. The non-dichroic omnidirectional structural color multilayer structure has an absorbing layer, a first layer extending across the absorbing layer, and a second layer extending across the first layer. The multilayer structure can reflect a narrow band of electromagnetic radiation that has a width of less than 500 nanometers and a center wavelength shift of less than 200 nanometers when the multilayer structure is viewed from angles between 0 and 45 degrees. In addition, the absorbing layer can block electromagnetic radiation reflected off of a surface that is proximate to the multilayer structure and thereby afford for a “pure” color that is not contaminated by reflected light from surrounding surfaces.

  • Publication number: 20050287369
    Abstract: Interference pigment flakes and foils are provided which have color shifting properties. The pigment flakes can have a symmetrical coating structure on opposing sides of a reflector layer, can have an asymmetrical coating structure with all of the layers on one side of the reflector layer, or can be formed with encapsulating coatings around a core reflector layer. The coating structure of the flakes and foils includes a reflector layer, a dielectric layer on the reflector layer, and a titanium-containing absorber layer on the dielectric layer. The pigment flakes and foils exhibit a discrete color shift so as to have a first color at a first angle of incident light or viewing and a second color different from the first color at a second angle of incident light or viewing. The pigment flakes can be interspersed into liquid media such as paints or inks to produce colorant compositions for subsequent application to objects or papers.

  • Publication number: 20050132929
    Abstract: The light transmitted and reflected by all-dielectric optically variable pigments varies according to viewing angle. The color travel of an all-dielectric optically variable pigment depends on amplitude changes and wavelength shifts in reflectance peaks of the pigment. The width and center wavelength of reflectance peaks can be controlled by selecting the ratio of thicknesses between high-index and low-index layers in a thin film stack. Reflectance peaks can regenerate or become suppressed and shift with tilt angle, thus providing a wide variety of color trajectories.
