RESIN DISPERSIONS HAVING UNIFORM PARTICLE DIAMETERS, RESIN PARTICLES AND PROCESSES FOR PRODUCING BOTH

摘要

The present invention provides a method of producing an aqueous dispersion which comprises dispersing a resin (b) or a solvent solution thereof, or a precursor (b0) of said resin (b) or a solvent solution thereof in an aqueous dispersion of resin particles (A) composed of resin (a) and causing the precursor (b0) to react in the case where the precursor (b0) or a solvent solution thereof is used, to prepare resin particles (B) composed of said resin (b) in said aqueous dispersion of resin particles (A) and thereby give an aqueous dispersion (X1) of resin particles (C) having a structure such that the resin particle (A) adheres to the surface of the resin particle (B). Further, an aqueous dispersion (X2) of resin particles (B) can be produced by a method which comprises cleaving the resin particle (A) and resin particle (B) from each other and removing resin particles (A), or which comprises dissolving resin particles (A). The present invention can make it possible to obtain resin particles of uniform particle diameter.
