    Abstract: A method for producing a resin particle dispersion includes: preparing a phase-inverted emulsion by phase inversion emulsification of a resin using an organic solvent and an aqueous medium; and removing the organic solvent from the phase-inverted emulsion contained in a distillation tank by reduced pressure distillation. During the reduced pressure distillation, the rate of pressure reduction in an environment in which the pressure inside the distillation tank is equal to or higher than vapor pressure and equal to or lower than (the vapor pressure+5 kPa) when the concentration of the organic solvent in the phase-inverted emulsion is in the range of 30% by mass or less to 1% by mass or more is from 0.01 kPa/min to 0.5 kPa/min inclusive until the pressure inside the distillation tank reaches a preset reduced pressure for the reduced pressure distillation.

  • Publication number: 20220306815
    Abstract: A method for producing a resin particle dispersion includes: obtaining a phase-inverted emulsion by adding a neutralizer to a resin solution prepared by dissolving a resin having an acid value in an organic solvent to thereby neutralize the resin and then adding an aqueous medium to the resulting resin solution to subject the resin to phase inversion emulsification; and removing the organic solvent from the phase-inverted emulsion. In the course of obtaining the phase-inverted emulsion, a maximum agitation power per unit mass (kg) of the resin when the resin solution containing the aqueous medium added thereto is agitated to perform the phase inversion emulsification is from 0.4 W to 20 W inclusive.
