Abstract:
1. An article comprising a substrate and a coating comprising pigment flakes, supported by the substrate; wherein each of the pigment flakes includes a magnetic or magnetizable material for magnetic alignment of the pigment flakes, and the pigment flakes are aligned so as to form an aligned pattern wherein a portion of the pigment flakes are parallel to the substrate along a continuous imaginary line on a surface of the substrate between first and second points thereof, and the pigment flakes form curved patterns in a plurality of cross-sections normal the continuous imaginary line so that radii of the curved patterns increase along the imaginary line from the first point to the second point; and, wherein, when light is incident upon the pigment flakes from a light source, light reflected from the aligned pattern forms a bright image which appears to gradually change its shape and move from one side of the continuous imaginary line to another side of the continuous imaginary line when the substrate is tilted with respect to the light source.
