摘要： A process for the preparation of toner compositions comprising(i) preparing a pigment dispersion in water, which dispersion is comprised of a pigment, an ionic surfactant and optionally a charge control agent;(ii) shearing the pigment dispersion with a latex containing a controlled solid contents of from about 50 weight percent to about 20 percent of polymer or resin, counterionic surfactant and nonionic surfactant in water, counterionic surfactant with a charge polarity of opposite sign to that of said ionic surfactant thereby causing a flocculation or heterocoagulation of the formed particles of pigment, resin and charge control agent to form a dispersion of solids of from about 30 weight percent to 2 percent comprised of resin, pigment and optionally charge control agent in the mixture of nonionic, anionic and cationic surfactants;(iii) heating the above sheared blend at a temperature of from about 5.degree. to about 25.degree. C. about below the glass transition temperature (Tg) of the resin while continuously stirring to form toner sized aggregates with a narrow size dispersity; and(iv) heating the electrostatically bound aggregated particles at a temperature of from about 5.degree. to about 50.degree. C. about above the (Tg) of the resin to provide a toner composition comprised of resin, pigment and optionally a charge control agent.
