    • The specification describes a process for making gelled ink resins which exhibit improved properties such as lower viscosity under low shear and less viscosity decrease with increasing shear. In a preferred embodiment, a rosin-based or hydrocarbon-based resin is mixed with an organic solvent and reacted with a polyamine reactant, such as melamine-formaldehyde resin or hexamethylene diamine, under conditions sufficient to produce a substantially covalently cross-link gelled resin. The resulting gelled resin resists viscosity breakdown under high shear conditions and may be used directly for making ink compositions, obviating the need for further gelation and avoiding the use of conventional organ-metallic gelling agents.
    • 本说明书描述了一种制备胶凝油墨树脂的方法,其表现出改进的性能,例如在低剪切下较低的粘度和较小的粘度随着剪切力的增加而降低。 在优选的实施方案中,将松香基或烃基树脂与有机溶剂混合,并在多胺反应物如三聚氰胺 - 甲醛树脂或六亚甲基二胺与足以产生基本上共价交联的胶凝树脂 。 所得胶凝树脂在高剪切条件下抵抗粘度破坏,并且可以直接用于制备油墨组合物,从而避免进一步凝胶化的需要,并避免使用常规的有机金属胶凝剂。
