Abstract The present article explores the usage of functionalized urethane of robust affinity to pigment through the reaction of polyurethane adduct with different types of polyether in order to improve the pigment dispersion stability, color and wetting properties. The raw materials and prepared dispersants were characterized by FTIR, GPC, Non-volatile content. The properties and dispersing ability of the dispersants were also investigated by measuring ink viscosity, Rheology, surface tension and particle size. The prepared polymeric dispersants were employed as dispersing agents for solvent-based inkjet ink application. The adhesion and color properties of prepared ink also were studied. All dispersants possessed high gloss comparing to blank after storage stability and low particle size and surface tension except PUD 5, 6, all dispersants showed no negative affect on adhesion of ink on printed PVC film and possessed excellent dispersing ability and rheological properties indicated by low ink viscosity for most commonly used cyan pigment C.I. 15:4.

聚氨酯作为溶剂型喷墨油墨分散剂的生动应用

摘要 本文探讨了通过聚氨酯加合物与不同类型的聚醚反应，使用对颜料具有强亲和力的官能化氨基甲酸酯，以改善颜料分散稳定性、颜色和润湿性能。通过FTIR、GPC、非挥发物含量对原料和制备的分散剂进行表征。还通过测量油墨粘度、流变学、表面张力和粒径来研究分散剂的性质和分散能力。制备的聚合物分散剂用作溶剂型喷墨油墨应用的分散剂。还研究了制备的油墨的附着力和颜色特性。除了 PUD 5、6、
