Abstract:
1. A method for producing an aqueous dispersion (X1), the method comprising; providing an aqueous dispersion liquid (W) of resin particles (A) comprising a resin (a), wherein the resin (a) is an epoxy resin, a vinyl resin, or a polyester resin (p1); providing a precursor (b0) of a resin (b), or an oily liquid (OL) comprising the precursor (b0) and an organic solvent, wherein the resin (b) comprises the polyester resin (p1) or a polyurethane resin (p2) having the polyester resin (p1) as constituent unit; mixing the aqueous dispersion liquid (W) with the precursor (b0) or the oily liquid (OL) to disperse the precursor (b0) in the aqueous dispersion liquid (W); causing the precursor (b0) to react in the aqueous dispersion liquid (W) to form resin particles (B) comprising the resin (b); and obtaining the aqueous dispersion (X1) of resin particles (C) having a structure where the resin particles (A) are adhered on the surface of the resin particles (B), wherein the polyester resin (p1) has been formed in the presence of a titanium catalyst (t) represented by the following general formula (I): wherein R represents a hydrogen atom, ethyl, n-propyl, isopropyl, n-butyl or n-hexyl, Ti represents a titanium atom, O represents an oxygen atom, and X represents a residue formed by removal of a hydrogen atom of one carboxyl group from benzoic acids or phthalic acids atoms, wherein X may react with OR groups in the same molecule intramolcularly to form a cyclic structure or react with OR groups of other molecules intermolecularly to form a structure having 2 to 5 titanium atoms, m=1 to 3, n =1 to 3, and the sum of m and n is 4.
