Abstract
A pigment, including 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 organic layer is disclosed. A colorant composition including the pigment is also disclosed. A method of making the pigment, and a method of making a colorant composition are also disclosed.
Claims18
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;
- an organic layer encapsulating the first inorganic layer;
- and
- a second inorganic layer encapsulating the flake.
