The present invention provides a magnetic multilayer pigment flake and a magnetic coating composition that are relatively safe for human health and the environment. The pigment flake includes one or more magnetic layers of a magnetic alloy and one or more dielectric layers of a dielectric material. The magnetic alloy is an iron-chromium alloy or an iron-chromium-aluminum alloy, having a substantially nickel-free composition. The coating composition includes a plurality of the pigment flakes disposed in a binder medium.

The present invention relates to particles comprising a core, in particular a magnetic core, and a first coating of a first shell material, wherein a second coating of a second shell material is applied to the surface of the first coating facing away from the core, the second shell material is different from the first shell material and has a higher refractive index than the first shell material.
