description	To provide a solvent-free phase-inversion emulsification process for producing amorphous polyester resin emulsions.SOLUTION: A process includes: forming a mixture by adding to an amorphous polyester resin, i. a surfactant, ii. an aqueous solution of a neutralizing agent, and iii. a portion of water that is about 40% or less of the total amount of water used to form a phase-inversion emulsion; heating the mixture to dissolve the amorphous polyester resin to provide a dissolved amorphous polyester; and adding water up to the total amount of water to the dissolved amorphous polyester to form a latex of the amorphous polyester resin. The resultant latex is used in processes of making a toner composition. A latex of an amorphous polyester resins is made by such processes and have latex particles that are unimodal.SELECTED DRAWING: Figure 1 【課題】非晶性ポリエステル樹脂エマルションを製造するための溶媒を含まない転相乳化プロセスの提供。【解決手段】非晶性ポリエステル樹脂に、ｉ．界面活性剤、ｉｉ．中和剤の水溶液、及びｉｉｉ．転相エマルションを形成するために使用される水の総量の約４０％以下である水の一部、を添加することによって混合物を形成することと、混合物を加熱して非晶性ポリエステル樹脂を溶解させ、溶解した非晶性ポリエステルを提供することと、溶解した非晶性ポリエステルに水の総量まで水を添加して、非晶性ポリエステル樹脂のラテックスを形成することと、を含む。得られたラテックスは、トナー組成物の製造プロセスにおいて使用される。非晶性ポリエステル樹脂のラテックスは、このようなプロセスによって作製され、単峰性のラテックス粒子を有する。【選択図】図１
