    摘要： A toner is disclosed that includes a toner binder of crystalline sulfonated polyester, wherein the crystalline sulfonated polyester is 90% by weight or more of the toner binder, and a colorant. In other embodiments, the toner includes a crystalline sulfonated polyester and a linear amorphous sulfonated polyester, and a colorant. In these embodiments, the crystalline sulfonated polyester is from about 20% to about 60% by weight of the toner binder and the linear amorphous sulfonated polyester is from about 40% to about 80% by weight of the toner binder. The toners possess excellent miniumum fixing temperatures in the range of from about 80° C. to about 130° C. Processes for preparing the toners are also described.

    摘要： A toner of a sulfonated polyester resin and at least one colorant is made to contain from about 0.01% by weigh to about 3% by weight of dry toner in total of lithium, sodium, zinc and calcium. The sulfonated polyester resin may be an alkali metal sulfonated polyester resin, wherein the alkali metal may be sodium and/or lithium. The toner may be formed in an emulsion aggregation process in which an alkali (II) metal salt such as a zinc salt and/or a calcium salt is used as an aggregating agent.

    摘要： A method of making particles suitable for use as toners includes forming a mixture of sulfonated olyester resin, a colorant dispersion and optionally a wax dispersion, homogenizing the mixture, adding a coagulant to the mixture to aggregate the mixture to form aggregated particles, and coalescing the aggregated particles to form coalesced particles. In the method, when a predetermined average particle size is achieved during the aggregation and/or coalescing step, a complexing agent that complexes with ions of the coagulant is added in an amount effective to substantially halt any further particle growth. The complexing agent is believed to halt further growth by complexing with free coagulant ions still in the solution.

    摘要翻译： 制备适合用作调色剂的颗粒的方法包括形成磺化的酯交酯树脂，着色剂分散体和任选的蜡分散体的混合物，使混合物均化，向混合物中加入凝结剂以将混合物聚集形成凝集颗粒，并将 聚集的颗粒形成聚结的颗粒。 在该方法中，当在聚集和/或聚结步骤期间达到预定平均粒径时，加入与絮凝剂的离子相配合的络合剂，其量可有效地基本上停止任何其它颗粒生长。 据信络合剂通过与仍在溶液中的游离凝结剂离子络合来停止进一步的生长。
