Patent ID: 7005480

Claim:
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 giving 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), wherein said resin (b) is at least one resin selected from the group consisting of polyurethane resin, epoxy resin, polyester resin, polyamide resin, polyimide resin, silicon resin, phenol resin, melamine resin, urea resin, aniline resin and polycarbonate resin, and wherein the volume average particle diameter of resin particles (A)/volume average particle diameter of resin particles (B) is 0.001 to 0.3.
