    • A self-dispersible bipyridine-based metal complex includes a bipyridine-based ligand and a metal, and an ink composition including the metal complex. The bipyridine-based metal complex may be self-dispersed without requiring a dispersing agent and may be used as a colorant per se. Furthermore, the metal complex, when binding with a common colorant, may produce various colors and exhibit enhanced durability including light resistance. In addition, the metal complex includes a hydrophilic group-containing ligand coordinating with the metal, in addition to the bipyridine-based ligand, and thus, has a bulky structure. Therefore, dispersion stability is enhanced by a self-dispersion system based on a steric hindrance due to the bulky structure of the metal complex and an electrostatic repulsive force between the charged metal and the hydrophilic group-containing ligand, thus enhancing a long-term storage stability.
    • 自分散的联吡啶类金属络合物包括基于联吡啶的配体和金属,以及包含金属络合物的油墨组合物。 基于联吡啶的金属络合物可以自分散而不需要分散剂,并且可以用作着色剂本身。 此外,当与普通着色剂结合时,金属络合物可以产生各种颜色并表现出包括耐光性在内的增强的耐久性。 此外,金属络合物除了基于联吡啶的配体之外,还包括与金属配位的含亲水基团的配体,因此具有庞大的结构。 因此,由于金属络合物的体积庞大的结构和带电金属与含亲水基团的配体之间的静电排斥力,基于空间位阻的自分散系统增强了分散稳定性,从而增强了长期储存 稳定性。

    • An ink composition includes a self-dispersible coloring agent that includes an ionic group and a non-ionic linear or cyclic ester or amide moiety on a surface of the coloring agent at a mole ratio of about 1:10 to about 10:1, an organic solvent, and water. The coloring agent has a modified surface, so that stability of the ink can be increased due to an interaction between the coloring agent and the organic solvent, the particle size of the coloring agent can be kept uniform, an adhering force with respect to a substrate is increased to minimize bleeding between colors of a printed image, waterfastness and rubfastness in dry and wet conditions are increased to obtain an excellent colorfastness, and resulting in a high quality printed image and an excellent storage stability.
    • 油墨组合物包括自分散性着色剂,其在着色剂的表面上以约1:10至约10:1的摩尔比包含离子基团和非离子直链或环状酯或酰胺部分, 有机溶剂和水。 着色剂具有改性表面,由于着色剂和有机溶剂之间的相互作用,可以提高油墨的稳定性,着色剂的粒径可以保持均匀,相对于基材的粘合力 增加以最小化印刷图像的颜色之间的渗色,提高干燥和湿润条件下的耐水性和耐磨性,以获得优异的耐色牢度,并且导致高质量的印刷图像和优异的储存稳定性。
