摘要： A printed image is disclosed wherein the image may be in the form of an array of magnetically aligned platelets or flakes that may be 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 (263) disposed upon a substrate (265) in the form of a Fresnel structure, preferably a Fresnel reflector. Advantageously, since the magnetic field (262) 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.

摘要： A color shifting interference structure is provided. The color shifting interference structure comprises: a magnetic layer, a reflector layer, a dielectric layer over the reflector layer, and an absorber layer over the dielectric layer. The interference structure exhibits a color shift such that the interference structure has 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 interference structure further comprises an insulator layer over the magnetic layer and the reflector layer is disposed over the insulator layer. The insulator layer has a thickness for preventing corrosion of the interference structure.

摘要： Device and process for producing indicia comprising magnetically oriented magnetic or magnetizable particles in ink or coating composition on a sheet of substrate material. Device includes a flat-bed screen-printing unit having a flat printing screen and a printing platen for receiving a sheet. Printing platen has an upper surface facing the printing screen and a first direction along its upper surface along which said sheet is unloadable, and a magnetic orienting unit having multiple magnet assemblies. Magnetic orienting unit is disposed below upper surface of the printing platen, the multiple magnet assemblies are disposed along first direction, and all of the magnet assemblies are concomitantly movable from a first position away from the upper surface of the printing platen to a second position close to the upper surface of the printing platen. The magnetic orienting unit having one or more magnet assemblies is usable as a stand-alone flat-bed magnetization device.

摘要： An object of the present invention is to provide a thin volume hologram sheet to be embedded sufficiently resistant to a mechanical stress such as a stress including a tensile stress, a shear stress and a compression stress at the time of processing even under a heating condition, a forgery prevention paper and a card using the same. The object is achieved by providing a volume hologram sheet to be embedded comprising a volume hologram layer, and a substrate disposed only on one side surface of the volume hologram layer using an adhesion means, wherein a peeling strength of the volume hologram layer and the substrate is 25 gf/25 mm or more.
