    摘要： A process for the preparation of a combination of color toners comprised of a cyan toner, a magenta toner, a yellow toner, and a black toner, each of said toners being comprised of resin and pigment, and wherein the pigment is cyan, magenta, yellow and black, each of the said pigments are dispersed in a nonionic, or neutral charge surfactant, and wherein each toner in the combination is prepared by (i) preparing a pigment dispersion, which dispersion is comprised of a pigment and nonionic water soluble surfactant; (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; and (iv) heating said bound toner size aggregates above about the Tg of the resin.

    摘要： A process for the preparation of toner comprising:(i) preparing a pigment dispersion, which dispersion is comprised of a pigment, and an ionic surfactant;(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, and wherein said resin contains an acid functionality;(iii) heating the above sheared blend below about the glass transition temperature (Tg) of the resin to form electrostatically bound toner size aggregates;(iv) adding anionic surfactant to stabilize the aggregates obtained in (iii);(v) coalescing said aggregates by heating said bound aggregates above about the Tg of the resin;(vi) reacting said resin of (v) with acid functionality with a base to form an acrylic acid salt, and which salt is ion exchanged in water with a base or a salt, optionally in the presence of metal oxide particles, to control the toner triboelectrical charge, which toner is comprised of resin and pigment; and(vii) optionally drying the toner obtained.
