摘要:
A process for the preparation of toner comprising generating a latex emulsion of resin, water, and an ionic surfactant, and a colorant dispersion of a surface modified colorant and water, and wherein the latex emulsion is blended with the surface modified colorant dispersion; heating the resulting mixture below or equal to about the glass transition temperature (Tg) of the latex resin to form aggregates; optionally adding a second latex comprised of submicron resin particles suspended in an aqueous phase resulting in a shell or coating wherein the shell is optionally of from about 0.1 to about 1 micron in thickness, and wherein optionally the shell coating is contained on 100 percent of the aggregates; heating the resulting aggregate suspension above about the Tg of the latex resin; and optionally isolating the toner.
