Abstract: A plurality of flakes are provided that can be used in ink or paint wherein the flakes are of a size that requires magnification to see their shape, in the form of polygons, such as squares, triangle or rectangles. A breaking or grinding process is used to break a foil into these shaped flakes and frames or walls are provided within the foil sheet so as to delineate the shapes and these lines provided by frames or walls will facilitate breakage in a preferred manner such that the flakes break into selected shaped polygons. Remnants are typically present along flake edges due to the grinding and breakage process however with magnification, one can see the resultant regular polygonal shape. To clearly see the remnants one requires increased magnification and the remnant itself provides a type of signature. It can be seen as a taggent within a taggent.

Abstract: In a plurality of asymmetric color-shifting flakes, each flake has an asymmetric magnetic core with a magnetic layer visible on the first side of the core and a non-magnetic reflector layer on the magnetic layer, visible on the second side of the core. The flake has a spacer layer and an absorber layer on the first side of the core, and also a spacer layer and an absorber layer on the second side of the core, for providing color shifting effects. The material of the magnetic layer is different from the material of the reflector layer, and may be more stable when exposed to a chemical. When a coating with the asymmetric color-shifting flakes is exposed to the chemical, it may have better optical performance than a coating with symmetric color-shifting flakes.

Abstract: An optically variable device may be manufactured by aligning magnetic flakes on a surface of an adhesive layer by applying the flakes onto the adhesive layer surface in presence of a magnetic field, and curing the adhesive layer having magnetic flakes adhered to the adhesive layer. When cured, the adhesive layer holds the magnetic flakes oriented, enabling subsequent encapsulation of the oriented magnetic flakes in a coating layer on the adhesive layer, without a substantial loss of orientation of the magnetic flakes.

Abstract: A security image and method of forming said image is disclosed wherein a substrate having an image or indicia thereon is coated with a dilute solution of pigment flakes in an ink or paint. The flakes are subsequently aligned in a magnetic field and are fixed after the field is applied. Most or all of the flakes in a region are aligned so as to be partially upstanding wherein their faces are essentially parallel. Coating the image with flakes yields a latent image which can be clearly seen at a small range of predetermined angles.
