    摘要： A metameric optical structure is disclosed having first optical structures comprising diffractive flakes having diffractive structures thereon, and a second optical structures having non-diffractive flakes which may have other special effect properties, such as color shifting. At one angle of incidence or one viewing angle, near normal. The hues match and at other angles they do not match. The diffractive flakes are preferably magnetically aligned so that the grating structures are parallel. Disclosed is also an image formed of at least a first region of diffractive flakes and a second region of non-diffractive flakes wherein the regions are adjacent one another and wherein one of the regions forms a logo, symbol or indicia that appears or disappears in dependence upon the angle of viewing.

    摘要： A method and image made by the method is disclosed wherein non-spherical magnetically alignable optical pigment flakes in transparent carrier are applied to a substrate and are aligned by applying a magnetic field to the substrate. The pigment flakes align along magnetic field lines and a tool for impressing or scribing the flakes is applied to a sub-region of the substrate to realign or remove flakes from a desired region. For example a scribing tool can be used to scribe a signature or other marks within the magnetically aligned flakes. The flakes are then cured and the image is preserved which has optical and tactile features.
