Abstract
An ink is disclosed. The ink includes a carrier fluid; an encapsulated metallic pigment particle further including a metallic pigment particle and a polymer, wherein the polymer covers between 70% and 100%, inclusive, of the surface area of the metallic pigment particle and wherein the morphology of the metallic pigment particle by itself is substantially the same as the morphology of the metallic pigment particle covered by the polymer; and a polymer resin.
Claims16
An ink including:
- a carrier fluid;
- an encapsulated metallic pigment particle including a metallic pigment particle, wherein the metallic pigment particle is acid-modified, and a polymer, wherein the polymer covers between 70% and 100%, inclusive, of the surface area of the metallic pigment particle and wherein the morphology of the metallic pigment particle by itself is substantially the same as the morphology of the metallic pigment particle covered by the polymer;
- a charge director, wherein the charge director is basic, and wherein the charge director negatively charges the metallic pigment particle;
- and
- a polymer resin.
