Abstract:
The present invention is drawn to a method of forming an encapsulated pigment dispersion and pigment dispersions that can be prepared therefrom. The method includes mixing a pigment particle in liquid vehicle dispersion with a mini-emulsion of monomers. A redox initiating agent is added to the liquid vehicle and the monomers are polymerized on the surface of the pigment particles. The resulting encapsulated pigment dispersion has a total solid content of at least 12 wt %.
