(57) [Summary] [Structure] A polyol (A) having an ion-forming property, A polyurethane polyurea crosslinked fine particle dispersion having an average particle diameter of 1 μm or less, which comprises polyisocyanate (B) and polyamine (C) as essential components, and a method for producing the same. The present invention has excellent storage stability, avoids modification of the core substance contained in the particles, and has excellent water resistance. It is possible to provide a strongly crosslinked polyurethane polyurea crosslinked fine particle dispersion having an average particle diameter of 1 μm or less, which has solvent resistance and chemical resistance and has a film-forming ability by itself, and a method for producing the same. |
