摘要： A task of the present invention is to obtain an aqueous polyurethane resin dispersion which is advantageous not only in that the dispersion exhibits excellent storage stability in an aqueous medium, but also in that after the dispersion is dried, a film having satisfactory flexibility is formed. In the present invention, there is provided an aqueous polyurethane resin dispersion comprising a polyurethane resin dispersed in an aqueous medium, wherein the polyurethane resin is obtained by reacting (A) a polyurethane prepolymer with (B) a chain extender, wherein the polyurethane prepolymer (A) is obtained by reacting (a) a polycarbonate polyol compound, (b) a polyisocyanate compound, (c) an acid group-containing polyol compound, and (d) a compound having one acid group and one hydroxyl group, wherein the chain extender (B) contains (B-1) a polyamine compound having three or more amino group(s) and/or imino group(s) in total.
摘要翻译：本发明的任务是获得水性聚氨酯树脂分散体，其优点在于不仅分散体在水性介质中表现出优异的储存稳定性，而且在分散体干燥后形成具有令人满意的柔性的膜。在本发明中，提供一种包含分散在水性介质中的聚氨酯树脂的水性聚氨酯树脂分散体，其中，聚氨酯树脂通过使（A）聚氨酯预聚物与（B）扩链剂反应得到，其中聚氨酯预聚物（ A）通过使（a）聚碳酸酯多元醇化合物，（b）多异氰酸酯化合物，（c）含酸基的多元醇化合物和（d）具有一个酸基和一个羟基的化合物反应而获得，其中链增量剂（B）含有（B-1）总共具有三个或多个氨基和/或亚氨基的多胺化合物。
