    摘要： Pigment flakes are blended together wherein some are magnetically alignable and exhibit a color shift from a first color to a second color with a change in viewing angle; and some are pigment flakes which exhibit a color shift from the first color to a third color or vice versa with a change in viewing angle, wherein the first, second and third colors are three different colors. The flakes are coated upon a substrate and magnetically alignable flakes are magnetically aligned. The non-magnetically alignable flakes are not aligned by the magnetic field and lie flat upon the substrate they are coated on. By judiciously selecting the angle upon which the magnetic flakes are oriented, an effect is created whereby an observer sees a color shift from a first color to a second or a first color to a third, when orienting the substrate by tilting it at different particular angles. The coated substrate can be used in security applications such as on currency or secure instruments.

    摘要： A security device is disclosed that has an image formed upon a substrate. The image has a first printed region and a second different printed region both printed with a same ink formulation of field alignable flakes. At least one of the printed regions has optically variable effects. One of the first and second printed regions at least partially surrounds the other. The second printed region is formed of thin parallel lines and the first printed region has substantially wider lines than are printed in the second printed region. The area density of the ink in a line in the first group of wider lines is greater than the area density of a line in the second group of narrower lines. A surprising effect of this image is that particles or flakes in the ink are field aligned so as to produce a visible kinematic dynamic effect visible in the first region and not visible in the second region when the image is tilted or rotated.

    摘要： Covert flakes having one or more symbols and/or a selected shape are used in a composition, such as ink or paint, to provide a covert security feature to an object. In some embodiments the composition includes base pigment, and the covert flakes are covert pigment flakes that match the visual characteristics of the base pigment. In another embodiment, clear covert flakes are mixed in the carrier with base pigment. In another embodiment, clear covert flakes are mixed in a varnish base to provide a clear composition that can be applied over an existing security feature or elsewhere. The composition is used to print a field on the object, such as a stock certificate or bank note, for example. The covert flakes are not readily detectable by causal observation under visible light. In one embodiment, illuminating the covert security feature with ultraviolet light causes a covert flake to fluoresce and allows the observer to identify the location of the covert flake so that cover indicia may be observed. In a particular embodiment, a covert flake having one or more symbols is located using non-visible radiation, and then observed under visible light to read the symbol(s) on the covert flake.
