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。

摘要： Disclosed is an oil-less toner composition exhibiting good low temperature release and stripping in fixing, enhanced surface gloss of fixed image, and/or OHP transparency. By controlling one or more properties, such as the relative thermal energy input during the EA aggregation/coalescence process, using a wax having a certain dispersion size (D50), molecular weight and/or melting temperature, the toner particle produced thereby can achieve optimal surface wax protrusion with a surface wax content of about 12 to about 25 weight percent. This is based on the total amount of wax in the toner, as determined by x-ray photoelectron spectroscopy (XPS). The contamination of wax on developing rolls, photoreceptor and carriers, which lowers the reliability of the developer, is suppressed with the present exemplary embodiment.
摘要翻译：公开了一种无油调色剂组合物，其在定影中表现出良好的低温释放和剥离，增强固定图像的表面光泽度和/或OHP透明度。通过控制一个或多个性能，例如在EA聚集/聚结过程期间的相对热能输入，使用具有一定分散体尺寸（D50），分子量和/或熔融温度的蜡，由此产生的调色剂颗粒可以达到最佳表面蜡突起具有约12至约25重量％的表面蜡含量。这是基于通过x射线光电子能谱（XPS）测定的调色剂中蜡的总量。在本示例性实施例中，抑制了显影辊，感光体和载体上的蜡污染，这降低了显影剂的可靠性。
