摘要: A process for the preparation of toner comprising(i) preparing, or providing a cationic emulsion resin latex comprised of a resin derived from at least one olefinic nonpolar monomer, a cationic olefinic monomer, a cationic free radical initiator, and optionally a chain transfer agent in an aqueous mixture comprised of a nonionic surfactant and a cationic surfactant, and which mixture is heated at a temperature of from about 60.degree. C. to about 95.degree. C.;(ii) adjusting the pH of said cationic latex to from about 10 to about 14 by the addition of a base;(iii) preparing, or providing a pigment dispersion, which dispersion is comprised of a pigment and an anionic surfactant, and optionally a charge control agent;(iv) shearing said pigment dispersion with the pH adjusted latex of (ii) and heating below about the resin Tg to form electrostatically bound toner size aggregates, and optionally adding a cationic surfactant to stabilize the size of the toner aggregates; and(v) heating said electrostatically bound toner size aggregates above about the Tg of the resin to form coalesced toner particles; followed by optionally filtering, washing and drying the toner obtained.
