Abstract
A method of making liquid toner for electrophotographic imaging by forming a mixture of a polyamide polymer, a good solvent therefor and a particulate pigment, heating the polymer/pigment/solvent mixture to form a solution thereof, cooling the resulting solution to precipitate fine polymer-encapsulated pigment particles of generally uniform size and morphology, removing the precipitated particles, removing the solvent and redispersing the resulting particles in dispersant medium along with a charge-control agent to form the liquid toner. A steric stabilizer can be added to the polymer-encapsulated pigment particle dispersion.
