-20. (canceled)
A pigment, comprising:
- a flake including a metal core having a first surface and a second surface, a first dielectric layer interfacing with a first surface of the metal core, and a second dielectric layer interfacing with a second surface of the metal core;
- a first inorganic layer encapsulating the flake;
- and
- an organic layer encapsulating the first inorganic layer;
- wherein the first inorganic layer includes an inorganic material chosen from oxides, nitrides, carbides, sulfides, fluorides, chlorides, bromides, compounds thereof, or combinations thereof.
