  • 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.
