Multilayered magnetic pigment flakes are provided. The pigment flakes can be a symmetrical coating structure on opposing sides of a magnetic core, or can be formed with the encapsulating coatings around the magnetic core. The magnetic core can be a dielectric layer between magnetic layers. Some embodiments of the pigment flakes exhibit a discrete color shift so as to have distinct colors at differing angles of incident light or viewing. The pigment flakes can be interspersed into liquid media such as paints or inks to produce colorant compositions for subsequent application to objects or papers. |
