Abstract: The invention relates to a method of aligning magnetic flakes, which includes: coating a substrate with a carrier having the flakes dispersed therein, moving the substrate in a magnetic field so as to align the flakes along force lines of the magnetic field in the absence of an effect from a solidifying means, and at least partially solidifying the carrier using a solidifying means while further moving the substrate in the magnetic field so as to secure the magnetic flakes in the carrier while the magnetic field maintains alignment of the magnetic flakes. An apparatus is provided, which has a belt for moving a substrate along a magnet assembly for aligning magnetic flakes. The apparatus also includes a solidifying means, such as a UV- or e-beam source, and a cover above a portion of the magnet assembly for protecting the flakes from the effect of the solidifying means.

Abstract: A colorant including a mixture of pigments is disclosed. The pigments have a similar coloration but different resistance to corrosion. The mixing ratio is selected to optimize the corrosion resistance against color brightness, and/or acidic corrosion resistance against alkali corrosion resistance of the colorant.

Abstract: A method is provided for manufacturing an image on a substrate, wherein the image includes an indicia and a frame. The method includes covering at least a portion the substrate with a carrier comprising magnetically alignable flakes, aligning the magnetically alignable flakes with a magnetic field of a magnetic assembly comprising a metal plate with an opening, and solidifying the carrier. The frame is formed at an edge of the opening and the indicia is visible within the frame. The magnetic assembly includes two magnets disposed so that the North pole of one magnet and the South pole of another magnet are proximate to the metal plate at opposite sides of the opening.

Abstract: A device includes a substrate and at least 1,000 flakes resting upon the substrate, each flake including a magnetic layer. The plurality of flakes are aligned so as to form a plurality of rings or curves, wherein within each ring or curve, flakes are tilted at a same angle with respect to the substrate and planes extending from surfaces of said flakes intersect with one another. The device provides a visible image of a single ring or curve when illuminated with a single light source, and three rings or curves are visible when three light sources illuminate the device. The device may be used as a printed light detector.
