摘要： A security article may include a substrate. The security article may include a layer of security ink. The layer of security ink may include a set of color-shifting interference particles. The security article may include a layer of magnetic color-shifting ink. The layer of magnetic color-shifting ink may include a set of magnetically aligned magnetic particles. A color-shifting property of the layer of security ink and a color-shifting property of the layer of magnetic color-shifting ink may have a threshold level of similarity to create a color matching effect.

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 display (10) according to the present invention comprises a first optical effect layer (12) including a first interface part (IF1), the first interface part being provided with recesses or protrusions arranged two-dimensionally at the minimum center-to-center distance in a range of 200 nm to 500 nm, each of the recesses or protrusions having a forward-tapered shape, a reflective material layer (13) covering at least a part of the first interface part (IF1), and a second optical effect layer (17) including, at a position of a first portion of the first interface part (IF1) that is covered with the reflective material layer (13), a portion that faces the reflective material layer (13) with the first optical effect layer (12) interposed therebetween or faces the first optical effect layer (12) with the reflective material layer (13) interposed therebetween, the second optical effect layer containing at least one of a cholesteric liquid crystal, a pearl pigment and a multilayer interference film. The display (10) achieves a higher forgery prevention effect.

摘要： A method is provided for freezing the orientation of orientable magnetic or magnetizable pigment particles by irradiation hardening the coating layer comprising the orientable magnetic or magnetizable pigment particles through the substrate carrying the coating layer. This method can be used in the protection of security documents, such as for example banknotes and identity documents, against counterfeit and illegal reproduction.

摘要： A security device comprising a microstructure and one or more curable fluids, in which the microstructure is configured to direct the one or more curable fluids from a local application zone of the microstructure to one or more regions of the microstructure prior to curing each curable fluid. Alternatively, the security device may comprise a microstructure; and one or more cured fluids; in which each cured fluid is derived from a corresponding curable fluid that is directed by the microstructure from a local application zone of the microstructure to one or more regions of the microstructure prior to curing each curable fluid.The microstructure can have a depth of at least 100 nm, and a spacing aspect ratio (depth to height) greater than 1 : 10. A process for fabricating a security device is also described.
