Beschreibung
Zusammenfassung:	To provide an emulsion particle-containing aqueous dispersion that allows long-term storage and has excellent dispersion stability and a method for producing the emulsion particle-containing aqueous dispersion.SOLUTION: A method for producing an emulsion particle-containing aqueous dispersion includes mixing an isocyanate-containing compound with an aqueous medium; heating the resultant mixture, under stirring, to a temperature that is equal to or higher than the phase inversion start temperature of the mixture and is also lower than the boiling point of the aqueous medium; and then cooling the mixture to a temperature that is lower than phase inversion start temperature of the mixture.SELECTED DRAWING: None 【課題】本発明は、長期保管可能な分散安定性に優れたエマルション粒子含有水性分散体およびエマルション粒子含有水性分散体の製造方法を提供することを目的とする。【解決手段】イソシアネート含有化合物と水性媒体とを混合し、得られた混合物を攪拌下で当該混合物の転相開始温度以上であって水性媒体の沸点未満の温度に加熱した後、前記混合物を当該混合物の転相開始温度よりも低い温度に冷却するエマルション粒子含有水性分散体の製造方法である。【選択図】なし
