    摘要： A dispersing agent characterized in that said dispersing agent is prepared by reacting primary and/or secondary amino groups of an amine compound comprising a polyamine (C) with isocyanate groups of a urethane prepolymer (E) having two isocyanate groups in one terminal region, wherein said urethane prepolymer (E) has been prepared by reacting hydroxyl groups in a vinyl polymer (A) having two hydroxyl groups in one terminal region with isocyanate groups in diisocyanates (B), and in that an amine number of said dispersing agent is 1 to 100 mgKOH/g is disclosed. The dispersing agent of the present invention has excellent dispersibility, flowability, and storage stability when used in small quantities. A pigment-dispersed product can be prepared therefrom, independently of the kinds of binder resin or solvent used. Further, the present invention is suitable for offset ink, gravure ink, resist ink for a color filter, inkjet ink, coating composition, and colored resin composition.

    摘要翻译： 一种分散剂，其特征在于所述分散剂是通过在一个末端区域中使包含多胺（C）的胺化合物的伯和/或仲氨基与具有两个异氰酸酯基团的氨基甲酸酯预聚物（E）的异氰酸酯基团反应制备的，其中 所述氨基甲酸酯预聚物（E）通过在一个末端区域中具有两个羟基的乙烯基聚合物（A）中的羟基与二异氰酸酯（B）中的异氰酸酯基团反应制备，并且所述分散剂的胺值为1〜 公开了100mgKOH / g。 本发明的分散剂在少量使用时具有优异的分散性，流动性和储存稳定性。 颜料分散产物可以由其制备，而与所使用的粘合剂树脂或溶剂的种类无关。 此外，本发明适用于胶印油墨，凹版油墨，滤色器用抗蚀剂油墨，喷墨油墨，涂料组合物和着色树脂组合物。
