Finely dispersed polyurethane polyurea crosslinked particles and process for producing the same |
摘要 |
<p>Finely dispersed polyurethane polyurea crosslinked particles having an average particle diameter of not greater than 1 mu m and essentially comprising (A) an ion-forming polyol, (B) a polyisocyanate, and (C) a polyamine; and a process for producing the same are disclosed. The present invention provides finely dispersed polyurethane polyurea crosslinked particles and a process for producing the same; the dispersed particles being firmly crosslinked and having an average particle diameter of not greater than 1 mu m, and the particle dispersion having high preservation stability, preventing the core substance, if encapsulated therein, from undergoing denaturation, and exhibiting per se film-forming properties to provide a film excellent in water resistance, solvent resistance and chemical resistance.</p> |
