    摘要： A process for the preparation of toner compositions with controlled particle size comprising:

    (i) preparing a pigment dispersion in water, which dispersion comprises a pigment, and an ionic surfactant in controlled amounts of from about 0 5 percent to about 10 percent based on the amount of water;
    (ii) shearing the pigment dispersion with a latex mixture comprised of a counterionic surfactant with a charge polarity of opposite sign to that of said ionic surfactant, a nonionic surfactant, and resin, thereby causing a flocculation or heterocoagulation of the formed particles of pigment and resin;
    (iii) further stirring of the resulting mixture to form electrostatically bound relatively stable toner size aggregates with a narrow particle size distribution;
    (iv) adding further surfactant to minimize further growth, or freeze the particle size in the coalescence step; and
    (v) heating above the glass transition temperature of the resin (Tg) to coalesce the statically bound aggregated particles to form said toner composition comprising resin and pigment.

    摘要： A process for the preparation of toner compositions comprising:

    (i) forming a dispersion of resin in an aqueous ionic surfactant solution from a latex prepared by emulsion polymerization utilizing an ionic surfactant and optionally a nonionic surfactant;
    (ii) preparing pigment dispersions in water of three different pigments each of a dissimilar color, each dispersion being comprised of a pigment dispersed in water and which preparation utilizes nonionic dispersants, and optionally an ionic surfactant of the same polarity as that employed in preparing the resin latex of step (i);
    (iii) blending the prepared resin dispersed as a latex with two, or optionally three of the different color pigment dispersions of step (ii), the total pigment loading in the water suspension being between 2 and 30 percent by weight of the solid contents of said suspension;
    (iv) adding an aqueous solution of counterionic surfactant as a coagulant to the formed resin-pigment blends, while continuously subjecting the mixture to high shear, to induce a homogeneous gel of the flocculated resin-pigments blend;
    (v)heating the above sheared gel at temperatures between about 20°C and about 5°C below the glass transition temperature (Tg) of the resin while continuously stirring at speeds between about 200 and about 500 revolutions per minute to form statically bound toner sized aggregates between about 0.5 and about 25 microns in average volume diameter with a narrow size dispersity and with a geometric size distribution (GSD) between 1.10 and 1.30, and subsequently optionally adding additional ionic surfactant in amounts of between 0.01 and 5 percent by weight of the solid content of the suspension, which ionic surfactant is of the same polarity as that utilized to form the resin and pigment dispersions, and wherein the ionic surfactant functions primarily to stabilize the particles against further growth during the following heating stage;
    (vi) heating the statically bound aggregated particles at temperatures of from between 25°C and 40°C above the Tg of the resin to form coalesced rigid particles of a toner composition comprised of polymeric resin, and pigment agent; and optionally
    (vii) separating and drying said toner.
