    摘要： A process involving, for example, the admixing of an emulsion latex, a colorant, and a tetra-alkylated quaternary ammonium halide salt complexing agent; and thereafter, heating in sequence about below the Tg of a resin contained in the latex and then heating about above the Tg glass transition temperature of a resin contained in the latex.

    摘要： A process for the preparation of toner including (i) gerating by emulsion polymerization in the presence of an initiator a first resin latex emulsion; (ii) generating by polycondensation a second resin latex optionally in the presence of a catalyst; (iib) dispersing the resin of (ii) in water; (iii) mixing (iib) with a colorant thereby providing a colorant dispersion; (iiib) mixing the resin latex emulsion of (i) with the resin/colorant mixture of (iii) to provide a blend of a resin and colorant; (iv) adding an aqueous inorganic cationic coagulant solution of a polymeric metal salt and optionally an organic cationic coagulant to the resin/colorant blend of (iiib); (v) heating at a temperature of from about 5 to about 10 degrees Centigrade below the resin Tg of (i), to thereby form aggregate particles and which particles are optionally at a pH of from about 2 to about 3.5; (vi) adjusting the pH of (v) to about 6.5 to about 9 by the addition of a base; (vii) heating the aggregate particles of (v) at a temperature of from about 5 to about 50 degrees Centigrade above the Tg of the resin of (i), followed by a reduction of the pH to from about 2.5 to about 5 by the addition of an acid resulting in coalesced toner; (viii) optionally isolating the toner.
