    • A process for the preparation of toner comprising mixing a colorant dispersion and a latex emulsion, and wherein there is accomplished a heating below about or equal to about the resin latex glass transition temperature to form aggregates followed by heating above about or equal to about the resin glass transition temperature to coalesce the aggregates; separating the toner formed, and subsequently adding to the toner in the form of a slurry a mixture of monomer and cleavable surfactant, cleaving the surfactant under basic conditions, and allowing the monomer to adsorb on the toner, then polymerizing and cooling, and wherein the cleavable surfactant is of the Formulas (I) or (II), or optionally mixtures thereof ##STR1## wherein R.sup.1 is a hydrophobic aliphatic, or hydrophobic aromatic group; R.sup.2 is selected from the group consisting of hydrogen, alkyl, aryl, alkylaryl, and alkylarylalkyl; R.sup.3 is hydrogen or alkyl; A is a hydrophilic polymer chain, and m represents the number of A segments
