    摘要： A process for the preparation of toner compositions comprising:(i) preparing a latex or emulsion resin comprised of a polyester core encapsulated within a styrene based resin shell by heating said polyester emulsion containing an anionic surfactant with a mixture of monomers of styrene and acrylic acid, and with potassium persulfate, ammonium persulfate, sodium bisulfite, or mixtures thereof;(ii) adding a pigment dispersion, which dispersion is comprised of a pigment, a cationic surfactant, and optionally a charge control agent, followed by the sharing of the resulting blend;(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 electrostatically bound aggregates above about the Tg of the resin.
