1. A method of manufacturing an article comprising:
- providing a coating having pigment flakes dispersed in a binder to a first side of a substrate, wherein the pigment flakes include a magnetic or magnetizable material,aligning the pigment flakes with a magnetic assembly comprising a magnet and a diverter, andfixing the binder;
wherein the magnet has top and bottom surfaces, and a through cut between the top and bottom surfaces whereby the top surface has a top opening and the bottom surface has a bottom opening, wherein a magnetic axis of the magnetic assembly extends in a direction from one to another of the top and bottom surfaces, wherein the diverter is adjacent to the top surface of the magnet, wherein the top opening is only partially covered by the diverter.

Abstract
An article includes a substrate and a graphical component forming an image and an optical component which includes magnetic pigment flakes aligned so as to form a frame pattern which surrounds the image. When light is incident upon the pigment flakes from a light source, light reflected from the frame pattern forms a dynamic frame which surrounds the image and appears to move as the substrate is tilted with respect to the light source. The image appears to be stationary when the dynamic frame appears to move.

13. A method of manufacturing an article, comprising:
-
providing a coating having pigment flakes dispersed in a binder to a substrate, wherein the pigment flakes include a magnetic or magnetizable material; aligning the pigment flakes with a magnetic assembly comprising a stack of one or more magnets, the stack having top and bottom surfaces and a through cut between the top and bottom surfaces, whereby the top surface has a top opening and the bottom surface has a bottom opening smaller than the top opening, and wherein a magnetic axis of the magnetic assembly extends in a direction from one to another of the top and bottom surfaces; and fixing the binder. - View Dependent Claims (14, 15)

16. A method of making an article, comprising:
-
providing a first coating having pigment flakes dispersed in a binder to a first side of a substrate, wherein the pigment flakes include a magnetic or magnetizable material; aligning the pigment flakes of the first coating with a magnetic assembly; fixing the binder in the first coating; providing a second coating having pigment flakes dispersed in a binder to the first coating, wherein the pigment flakes of the second coating include a magnetic or magnetizable material; aligning the pigment flakes of the second coating with the magnetic assembly; and fixing the binder in the second coating; and wherein the magnetic assembly includes different magnets for aligning the first coating and the second coating. - View Dependent Claims (17, 18, 19)
