  • Patent number: 10752042
    Abstract: An article includes a substrate and a graphical component forming an image and an optical component which includes magnetic pigment flakes aligned so as to form a frame pattern which surrounds the image. When light is incident upon the pigment flakes from a light source, light reflected from the frame pattern forms a dynamic frame which surrounds the image and appears to move as the substrate is tilted with respect to the light source. The image appears to be stationary when the dynamic frame appears to move.

  • Publication number: 20200215845
    Abstract: In a printed article, pigment flakes are magnetically aligned so as to form curved patterns in a plurality of cross-sections normal a continuous imaginary line, wherein radii of the curved patterns increase along the imaginary line from the first point to the second point. When light is incident upon the aligned pigment flakes from a light source, light reflected from the aligned pattern forms a bright image which appears to gradually change its shape and move from one side of the continuous imaginary line to another side of the continuous imaginary line when the substrate is tilted with respect to the light source.

  • Publication number: 20190249013
    Abstract: The invention provides a plurality of substantially same planar pigment flakes, each formed of one or more thin film layers. Each flake has a face surface and a flake border delimiting the face surface; the flake border undulates in the plane of the flake. The flakes have a pre-selected shape, may have a symbol or a grating thereon. A method of manufacturing of these flakes including the steps of: (a) providing a substrate having a plurality of one-flake regions and a plurality of depressions or protrusions disposed therebetween and not extending into the one-flake regions, (b) coating the substrate with a releasable coating, and (c) removing the releasable coating and breaking it into the flakes; wherein two adjacent of the one-flake regions are separated by at least three of the depressions or protrusions for facilitating the breaking of the releasable coating into the flakes.

  • 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: 4917497
    Abstract: A holographic technique for the detection of position of known items so as to be able to reject those samples which do not lie within certain defined spatial parameters. A plate which contains a single exposure of the three dimensional holographic image of an object is illuminated by parallel reference beams from a laser to allow the reconstruction of a real focused image of the object. A displacement translator supports the object and permits displacement thereof in three directions all at right angles to one another. The coincidence of the object and its holographic image are detected either optically by means of a stereoscopic microscope, or electrically by means of a stereoscopic microscope and a photo-diode.
