ABSTRACT:
An ink for ink jet printing includes an emulsifiable polymer resin and a pigment, and may be made by: (a) combining (1) an emulsion of an emulsifiable polymer resin in an anionic medium with (2) a pigment and a cationic surfactant; and (b) aggregating particles in the mixture of step (a) to a desired particle size, thereby producing a solution of aggregated particles. The particles can optionally be coalesced to alter the particle size of the particles.
