摘要： Diffractive pigment flakes are selectively aligned to form an image. In one embodiment, flakes having a magnetic layer are shaped to facilitate alignment in a magnetic field. In another embodiment, the flakes include a magnetically discontinuous layer. In a particular embodiment, deposition of nickel on a diffraction grating pattern produces magnetic needles along the grating pattern that allow magnetic alignment of the resulting diffractive pigment flakes. Color scans of test samples of magnetically aligned flakes show high differentiation between illumination parallel and perpendicular to the direction of alignment of the magnetic diffractive pigment flakes. In another embodiment diffractive pigment flakes are selectively aligned by electrical fields. In other embodiments, special diffractive optical variable images are described and the method to produce them.

摘要： A laser toner includes optical effect taggent flakes or other structures in a binder suitable for binding particles to a substrate. Preferably the optical effect taggent structures have a substantially same shape or same indicia within the binder sized to be suitable for laser printing. After printing the flakes or structures become bonded to the substrate they are printed upon and are discernable by viewing with magnification.

摘要： The reinforced opaque glitter particles have a substantially uniform shape and size. Each of the particles includes a reflective core supported by a transparent organic substrate and one or more robustness-improving layers for providing rigidity to the particle. Optionally, the particles have lacquer layers at a surface of the particle. One example of a robustness-improving layer is an inorganic transparent protective layer having a thickness of at least 20 nm adjacent directly to the aluminum layer. Another example is an adhesion promoting layer directly adjacent to the transparent organic substrate.

摘要： 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.

摘要： Apparatus and related methods align magnetic flakes in a carrier, such as an ink vehicle or a paint vehicle to create optically variable images in a high-speed, linear printing operation. Images can provide security features on high-value documents, such as bank notes. Magnetic flakes in the ink are aligned using magnets in a linear printing operation. Selected orientation of the magnetic pigment flakes can achieve a variety of illusive optical effects that are useful for decorative or security applications.

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.
