Estimating the term…
The method for manufacturing of dispersion of fine resin particles of the present invention first emulsifies or disperses a polycondensable monomer for purposed fine resin particles into an aqueous medium. At this time, additives, such as a catalyst, a surfactant, and the like, are also added into the water soluble medium, as required. By subjecting this solution to, for example, heat, or the like, polycondensation proceeds. In this polycondensation, a strong acid salt is used as a polycondensation promoter. In addition, by using the obtained dispersion of fine resin particles, an electrostatic charge image developing toner is manufactured.
A polycondensation promoter comprising a strong acid salt.
A method for manufacturing a dispersion of fine resin particles comprising emulsifying or dispersing a polycondensable monomer in an aqueous medium;
A dispersion of fine resin particles in which the fine resin particles are dispersed in an aqueous medium, wherein the fine resin particles contain a polycondensation promoter comprising a strong acid salt.
A method for manufacturing an electrostatic charge image developing toner, comprising aggregating fine resine particles in a dispersion of the fine resine particles in an aqueous medium, the fine resin particles containing a polycondensation promoter comprising a strong acid salt, heating and fusing the aggregated fine resin particles.
An electrostatic charge image developing toner having a strong acid salt.
