| titleOfInvention | Method for producing dispersion of resin particles having acid group, and method for producing toner for developing electrostatic image using the dispersion |
| abstract | Even if there are variations in the physical properties of a resin having an acid group and the properties of a solution containing the resin, it is possible to stably obtain particles of the resin having a sharp particle size distribution and a desired particle size. The present invention provides a means for stably producing a toner having a sharp particle size distribution and a small amount of fine powder and coarse powder. A method for producing a dispersion of resin particles having an acid group using a phase inversion emulsification method including the following steps; Step 1: A step of mixing a resin having an acid group and an organic solvent to prepare a solution Step 2: A neutralizing agent is added to and mixed with the solution obtained in Step 1, and the liquid viscosity is 100 to 1000 mPa ยท Step of obtaining a neutralized mixed solution that is s Step 3: After confirming the liquid viscosity of the neutralized mixed solution obtained in Step 2, the amount is 0.5 to 50 with respect to 100 parts by mass of the resin having an acid group. Step of adding water at an addition rate of parts by mass / min to obtain an emulsion of resin particles having acid groups Step 4: Removal of the organic solvent from the emulsion obtained in Step 3 of the resin particles having acid groups A step of obtaining a dispersion. [Selection figure] None |
