    • 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
    • 一种制备调色剂的方法,包括混合着色剂分散体和胶乳乳液,并且其中完成低于大约或等于约树脂胶乳玻璃化转变温度的加热,以形成聚集体,然后加热至大约或等于约树脂 玻璃化转变温度以聚集聚集体; 分离形成的调色剂,然后将浆料形式的调色剂加入到单体和可切割表面活性剂的混合物中,在碱性条件下裂解表面活性剂,并使单体吸附在调色剂上,然后聚合和冷却,其中 可分解的表面活性剂是式(I)或(II)或其任选的其中R 1是疏水性脂族或疏水性芳族基团的混合物; R2选自氢,烷基,芳基,烷基芳基和烷基芳基烷基; R3是氢或烷基; A是亲水性聚合物链,m表示A链段的数目
