Abstract
The present invention is a method of manufacturing ink. The method includes providing a first organic phase of a solvent containing a dissolved polymer, an oil and a pigment. The organic solvent is dispersed in an aqueous phase containing a stabilizer to form an emulsion containing droplets of the organic phase. The solvent is removed from the droplets to form discrete particles having multiple domains of oil and pigment.
Claims15
A method of manufacturing ink polymer particles comprising:
- providing an organic phase comprising a solvent containing a dissolved polymer, an oil, and a pigment;
- dispersing the organic phase in an aqueous phase containing a stabilizer to form an emulsion containing droplets of the organic phase;
- and
- removing the solvent from the droplets to form discrete polymer particles comprising a solid phase having multiple domains of a liquid phase comprising oil and pigment contained therein;
- wherein the oil does not solubilize the solid phase of the discrete polymer particles.
