An ink for ink jet printing includes a liquid vehicle comprising water and toner particles with a colorant dispersed in or associated with the toner particles. The ink composition combines the print quality advantages of xerographic printing with the economic advantages of ink jet printing, thereby providing waterfast, archival quality prints.
A process for the preparation of toner compositions comprising: (i) preparing a pigment dispersion, which dispersion is comprised of a pigment, an ionic surfactant, and optionally a charge control agent; (ii) shearing said pigment dispersion with a latex or emulsion blend comprised of resin, a counterionic surfactant with a charge polarity of opposite sign to that of said ionic surfactant and a nonionic surfactant; (iii) heating the above sheared blend below about the glass transition temperature (Tg) of the resin, to form electrostatically bound toner size aggregates with a narrow particle size distribution; and (iv) heating said bound aggregates above about the Tg of the resin.
