Abstract: The present disclosure provides processes for reducing the particle size of latex resins and toners produced with such resins. In embodiments, a carboxylic acid may be added to materials utilized to produce a latex and reduce the particle size of the resulting latex particles and toner particles. In accordance with the present disclosure, one may be able to utilize materials for the production of latex resins and toners which may otherwise produce particles that are too large in the absence of the carboxylic acid.

Abstract: A washing process using one or more ionic liquids (ILs) as a washing aid agent for toners, including toners produced using such ILs, such as, low melt toners, is provided. ILs are environmentally sound, green solvents that act to swell toner particle surfaces so that surface absorbed and adsorbed pollutants, such as, surfactants and other manufacturing reactants, can be effectively removed. The resulting toners have good charging, charge maintenance and RH sensitivity.

Abstract translation: 提供了使用一种或多种离子液体（ILs）作为调色剂的洗涤助剂的洗涤方法，包括使用这种IL制备的调色剂，例如低熔点调色剂。 ILs是无害环境的绿色溶剂，其用于溶胀调色剂颗粒表面，从而可以有效地除去表面吸收和吸附的污染物质，例如表面活性剂和其它制备反应物。 所得调色剂具有良好的充电，充电维护和RH灵敏度。
