Abstract:
A process for the preparation of toner comprising (i) blending (a) an aqueous pigment dispersion containing a first ionic surfactant and an optional charge control agent with (b) a latex blend comprised of linear polymer and crosslinked polymer particles, optional nonionic surfactant and a second ionic surfactant with a charge polarity opposite to that of said first ionic surfactant in said pigment dispersion; (ii) heating the resulting mixture at about below the glass transition temperature (Tg) of the linear latex polymer to form toner sized aggregates; and (iii) subsequently heating said aggregate suspension about above the Tg of the linear latex polymer to effect fusion or coalescence of said aggregates.
