Abstract:
1. A security device comprising: a coating forming an image having a first region and a second region adjacent to and visually distinguishable from the first region, wherein the coating is coated upon a substrate, wherein the coating is an ink or paint and wherein the coating comprises a mixture of a plurality of magnetically orientable flakes and a plurality of magnetically non-orientable flakes; wherein the magnetically orientable flakes and magnetically non-orientable flakes are substantially planar flakes each having two faces separated by edges defined by the thickness of the magnetically orientable flakes and magnetically non-orientable flakes; wherein the concentration of the mixture of the magnetically orientable flakes and the magnetically non-orientable flakes within the first region and second region is the same, wherein the magnetically orientable flakes within the first region are aligned so as to be substantially upstanding on or with respect to the substrate such that no faces of the magnetically orientable flakes can be seen when viewing the image and wherein the magnetically non-orientable flakes in the first region are substantially orthogonal to the substantially upstanding magnetically orientable flakes such that the magnetically non-orientable flakes are lying flat upon and parallel to the substrate so that the faces of the magnetically non-orientable flakes within the first region can be seen when viewing the image, and wherein the magnetically orientable flakes and magnetically non-orientable flakes within the second region are substantially parallel to the substrate so as to be lying flat upon the substrate and wherein the faces of the magnetically orientable flakes and magnetically non-orientable flakes within the second region can be seen within the second region when viewing the image, wherein a difference in appearance due to the orientation of the magnetically orientable flakes in the first region and the second region forms a visible contrast, wherein the edges of the magnetically orientable flakes in the first region are visible under magnification and wherein the faces of the magnetically orientable flakes are not visible and wherein one of the first or second regions forms a logo, insignia or text.
