Process for producing resin particle liquid dispersion for electrostatic image developing toner, electrostatic image developing toner and production process thereof
Abstract:
A process for producing a resin particle liquid dispersion for an electrostatic image developing toner, the process comprising: polycondensing a polycondensable monomer by utilizing an acid having a surface activating effect as a polycondensation catalyst, so as to obtain a polycondensed resin; and dispersing the polycondensed resin in an aqueous medium to which a base is added, so as to obtain a resin particle liquid dispersion in which a median diameter of resin particles is from 0.05 to 2.0 μm, or the process comprising: polycondensing a polycondensable monomer by utilizing an acid having a surface activating effect as a polycondensation catalyst in a co-presence of a polycondensed resin, so as to obtain a polycondensed resin-containing material; and dispersing the polycondensed resin-containing material in an aqueous medium, so as to obtain a resin particle liquid dispersion in which a median diameter of resin particles is from 0.05 to 2.0 μm.
Abstract(Chinese):

一种用于静电图像显影调色剂的树脂颗粒分散液的制备方法，该方法包括：通过利用具有表面活化作用的酸缩聚缩聚单体作为缩聚催化剂，以获得缩聚树脂; 并将该缩聚树脂分散在添加了碱的水性介质中，得到树脂粒子的中值粒径为0.05〜2.0μm的树脂粒子分散液，或者将聚缩聚单体缩聚为 在缩聚树脂的共存下，利用具有表面活化作用的酸作为缩聚催化剂，得到含缩聚树脂的材料; 并将含缩聚树脂的材料分散在水性介质中，以获得其中树脂颗粒的中值粒径为0.05-2.0μm的树脂颗粒液体分散体。
