METHOD FOR PRODUCING RESIN DISPERSION AND RESIN PARTICLE

摘要

Disclosed is a method for producing an aqueous dispersion (X1), which is characterized by comprising a step for obtaining an aqueous dispersion (X1) of a resin particle (C) having a structure wherein a resin particle (A) adheres to the surface of a resin particle (B), in which step an aqueous dispersion (W) of the resin particle (A) composed of a resin (a) is mixed with a precursor (b0) of a resin (b) or with an oily liquid (OL) composed of the precursor (b0) and an organic solvent, thereby dispersing the precursor (b0) or the oily liquid (OL) in the aqueous dispersion (W) and forming the resin particle (B) composed of the resin (b) by causing a reaction of the precursor (b0) in the aqueous dispersion (W). This method for producing an aqueous dispersion (X1) is also characterized in that at least one of the resin (a) and the resin (b) contains a polyester resin (p1) which is formed in the presence of a specific titanium catalyst (t), or a resin (p2) which has the polyester resin (p1) as a constitutional unit.
