Abstract:
1. A water-based dispersion (X1) of resin particles (C1) comprising resin particles (B) bearing resin particles (A) on the surface thereof and obtained by mixing a water-based dispersion (W) of the resin particles (A) comprising a first resin (a) with a second resin (b) or its solvent solution, alternatively a precursor (b0) of the resin (b) or its solvent solution and dispersing the resin (b) or its solvent solution, alternatively the precursor (b0) of the resin (b) or its solvent solution, further causing a reaction of (b0) in the case of using (b0) or its solvent solution, in the water-based dispersion (W); and thereby forming the resin particles (B) comprising (b) in the water-based dispersion (W) of (A), wherein resin (a) contains a constituent unit of the following organic acid metal salt (m), and/or (A) contains the following organic acid metal salt (m), and wherein resin (a) contains 20 to 80% by weight of vinyl acetate as constituent units, and resin (a) does not comprise a polyurethane resin, and is either thermoplastic resin or thermosetting resin, and wherein the resin (b) comprises a polyurethane resin: organic acid metal salt (m): one or more kinds of salts selected from carboxylic acid salts, sulfonic acid salts, and phosphoric acid salts of a metal selected from Ti, Cr, Mn, Fe, Zn, Ba, and Zr.
