Toner processes

Abstract

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