碳化二亚胺类水性树脂交联剂
Abstract:
本发明提供了一种在与水性树脂并存状态下的保存稳定性优良的碳化二亚胺类水性树脂交联剂，该碳化二亚胺类水性树脂交联剂含有聚碳化二亚胺(A)和聚碳化二亚胺(B)，且所述聚碳化二亚胺(B)相对于所述聚碳化二亚胺(A)的质量比[(B)/(A)]为20/80～95/5；所述聚碳化二亚胺(A)在两末端具有来自亲水性有机化合物的取代基，所述取代基中的至少一个取代基为来自分子量340以上的亲水性有机化合物的取代基；所述聚碳化二亚胺(B)在两末端具有来自分子量300以下的有机化合物的取代基。
Abstract(English):

Provided is a carbodiimide-based aqueous resin crosslinking agent that has an excellent storage stability when coexisting with an aqueous resin and that contains: a polycarbodiimide (A) that has, on both terminals, substituents derived from a hydrophilic organic compound, at least one of the substituents being derived from a hydrophilic organic compound having a molecular weight of at least 340; and a polycarbodiimide (B) that has, on both terminals, substituents derived from an organic compound having a molecular weight not exceeding 300, wherein the mass ratio [(B)/(A)] of the polycarbodiimide (B) to the polycarbodiimide (A) is 20/80 to 95/5.
