    摘要: An article with a surface with a paint film adherent thereto having a liquid medium hardened into a solid to form said paint film and having first and second parallel surfaces with the first parallel surface being adhered to the surface of the article and the second surface exposed to be viewed by the human eye. A plurality of flakes are provided having first and second planar parallel surfaces lying in said paint film with the first and second planar parallel surfaces being parallel to the first and second parallel surfaces of the paint film. The flakes are characterized in that they have physical dimensions such that when the dimensions of the flakes are measured parallel to and perpendicular to the respective first and second planar parallel surfaces, an aspect ratio of at least two-to-one is provided. Each of the flakes has a symmetrical optically variable multilayer thin film interference structure including at least one thick substantially opaque metal reflecting layer having first and second surfaces and a multilayer thin film including at least one thin semi-transparent metal layer and at least one dielectric layer formed of an inorganic material with an index of refraction of 1.65 or less and disposed on each side of the substantially opaque metal reflecting layer. The multilayer thin film structure produces a shift in color between two distinct colors when the angle of incident light on the paint film is shifted between two different angles.

    摘要: Optically variable ink for obtaining a color shaft between two distinct two colors at first and second angles of incident light comprised of an ink vehicle and optically variable flakes disposed in the ink vehicle. The optically variable flakes are comprised of a multilayer thin film interference structure having first and second parallel planar surfaces. The optically variable flakes have physical dimensions such that when the flakes are measured in directions parallel and perpendicular respectively to the planar surfaces an aspect ratio of at least 2 to 1 is provided. The multilayer thin film structure is of symmetrical design and includes a metal reflector having first and second surfaces parallel to the first and second parallel planar surfaces and at least one period disposed on each of said first and second surfaces of the metal reflector. Each period is comprised of a dielectric layer with an index of refraction of 1.65 or less and a semi-opaque layer.

    摘要: Interference pigment flakes and foils are provided which have luminescent and color-shifting properties. The pigment flakes can have a symmetrical coating structure on opposing sides of a core layer, can have an asymmetrical coating structure with all of the layers on one side of the core layer, or can be formed with encapsulating coatings around the core layer. The coating structure of the flakes and foils includes a core layer, a dielectric layer overlying the core layer, and an absorber layer overlying the dielectric layer. A luminescent material is incorporated into the flakes or foils as a separate layer or as at least part of one or more of the other layers. 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 materials for subsequent application to objects or papers. The foils can be laminated to various objects or can be formed on a carrier substrate.
