An article including at least one first metallic layer, at least one dielectric layer; and at least one second metallic layer is disclosed. The at least one dielectric layer can include at least one of (i) a photo-initiator, (ii) an oxygen inhibition mitigation composition, (iii) a leveling agent, and (iv) a defoamer.

A method is provided for producing platelet-shaped pigments, including the steps of: providing a film structure which has a carrier substrate, a water-soluble release layer and a pigment material layer; mechanically disrupting the pigment material layer, which is present in the film structure, at specific locations; soaking the film structure with aqueous solution; subjecting the film structure to a mechanical force so that the pigment material layer is detached from the carrier substrate as a plurality of pigments according to the ruptures present at the specific locations.

A pigment flake may comprise a multilayer optical structure. The multilayer optical structure may have a first surface with a first modulation that corresponds to a relief of a diffraction grating. The multilayer optical structure may have a second surface having a second modulation, with the second surface being opposite from the first surface and the second modulation being smaller than the first modulation such that the second surface is comparatively flatter than the first surface. The multilayer optical structure may exhibit diffraction colors for a first range of angles of the multilayer optical structure with respect to an angle of incident light, and may exhibit an interference color for a second range of angles of the multilayer optical structure with respect to the angle of the incident light.

A composition including a dual cavity color shirting pigment and a single cavity color shifting pigment is disclosed. A method of making the composition is also disclosed.
