    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.

    摘要： Multilayer chromatic diffractive pigment flakes and foils are provided having diffractive structures thereon. The diffractive pigment flakes can have a symmetrical stacked coating structure on opposing sides of a reflective core layer, an asymmetrical stacked coating structure on one side of a reflective layer, or can be formed with one or more encapsulating coatings around the reflective core layer. The diffractive pigment flakes can be interspersed into liquid media such as paints or inks to produce diffractive compositions for subsequent application to a variety of objects. The foils can be laminated to various objects or can be formed on a carrier substrate. The diffractive pigment flakes and foils can be formed with a variety of diffractive structures thereon to produce selected optical effects.

    摘要： A security image is disclosed which is formed from flakes having a first color with flakes having a second different color mixed within a carrier uniformly. The flakes having the second color are magnetically orientable and the flakes having the first color are non-magnetic and do not align or orient in a magnetic field. By exposing at least a single coated region to a magnetic field that is substantially orthogonal to the substrate upon which the coating of flakes is coated, a visible region having the first color is provided as the magnetic flakes are upstanding and the non-magnetic flakes are lying flat upon the substrate. In another region where there is no field applied a visible region having third perceived color different from, however formed from the first color or the second color is seen.
