Abstract
In an example of a method for making polymer-encapsulated metallic ink pigment particles, a layer of a transparent resin dispersion is disposed on a flexible substrate. The resin dispersion layer is substantially dried, and a base resin layer is formed. A slurry is disposed onto the base resin layer. The slurry includes metallic pigment particles and polymer particles dispersed in a non-aqueous carrier. The slurry is dried to form a metallic pigment-polymer sheet. Another layer of the transparent resin dispersion is disposed on the metallic pigment-polymer sheet and is dried. A coating resin layer is formed. The metallic pigment-polymer sheet and the base and coating transparent resin layers form a tri-layer film having the metallic pigment particles encapsulated between the base and coating transparent resin layers.
