  • Patent number: 10597538
    Abstract: A diffractive pigment blend or composition is provided which includes a plurality of groups of all-dielectric diffractive pigment flakes. The pigment flakes of each group each include one or more dielectric layers for providing a background color, at least one of which includes a diffractive structure for providing a diffractive effect. Each group of pigment flakes provides a different diffractive effect, and the diffractive pigment blend or composition provides a combined diffractive effect that is a combination of the different diffractive effects. The combined diffractive effect may be a neutral white diffractive effect or may include a reversal in color travel.

  • Patent number: 10329429
    Abstract: A security device has a support substrate of a first material having a softening temperature t1 and an embossed layer of a second different material supported by the support substrate having a softening temperature t2, wherein t2<t1. A thin film coating deposited directly upon the embossed layer, wherein the embossed layer is capable of being dissolved in a dissolving agent and wherein the thin film coating is not dissolvable by said dissolving agent. There is not need for an additional release layer as the second different material is dissolvable and allows flakes to be formed by dissolving the second layer.

  • Patent number: 10300729
    Abstract: A color shifting security device has a Fabry-Perot type structure wherein a dielectric layer is disposed between a reflector and an absorbing layer. The absorber and reflector layers may be conforming and the dielectric layer therebetween is non-conforming, filling the regions in the micro structured adjacent absorbing or reflecting layer, at least one of which has a microstructure therein or thereon. By having the dielectric layer not conform to the microstructure it is next to, its thickness varies in cross section, which allows for different colors to be seen where the thickness varies.

  • Patent number: 10173455
    Abstract: A printed image is disclosed wherein the image may be in the form of an array of magnetically aligned platelets or flakes that may by uniform in shape and size and wherein the flakes are arranged in a particularly manner to form optically illusive images useful as security devices, or useful in beam steering applications. In one embodiment of this invention printed array is disclosed a plurality of concentric rings of magnetically aligned platelets disposed upon a substrate in the form of a Fresnel structure, preferably a Fresnel reflector. Advantageously, since the magnetic field can be controlled with respect to strength and direction, one can easily design a field that will correct for spherical aberration that would otherwise be present in a typical Fresnel reflector. In other embodiments of the invention optically illusive images of funnels, domes and cones are printed.
