Abstract: A process for making a latex emulsion including contacting at least one amorphous polyester resin with at least two organic solvents to form a resin mixture, adding a neutralizing agent, and deionized water to the resin mixture, removing the solvent from the formed latex, and separating the solvent from water. Further, the process is carried out above the resin Tg for making the latex, which drives the latex particle size under 100 nm, where toners made from the latex show improved charging performance.
Abstract translation: 一种制备胶乳乳液的方法，包括使至少一种无定形聚酯树脂与至少两种有机溶剂接触以形成树脂混合物，向树脂混合物中加入中和剂和去离子水，从形成的胶乳中除去溶剂，并分离 来自水的溶剂。 此外，该方法在制造胶乳的树脂Tg之上进行，其驱动胶乳粒径在100nm以下，其中由胶乳制成的调色剂显示出改善的带电性能。
