    • Pigments that have been at least partially treated to form surface-attached functional groups are combined with long chain amine oxides in an ink-jet ink to provide waterfastness. The ink-jet ink for ink-jet printing comprises: (a) a vehicle comprising (1) 0 to about 30 wt % of at least one organic solvent, and (2) 0 to about 30 wt % of at least one water-soluble surfactant, and (3) about 0.1 to 10 wt % of at least one zwitterionic surfactant; (b) about 1 to 20 wt % of at least one chemically-modified, water-soluble macromolecular chromophore comprising a pigment having functional groups covalently attached thereto; and (c) the balance water. The inks of the invention evidence increased waterfastness with the presence of the zwitterionic surfactant, yet other properties, such as decap, kogation, and edge acuity, are not adversely affected by the presence of the zwitterionic surfactant. Indeed, decap and edge acuity are improved by the presence of the zwitterionic surfactant.
    • 已经至少部分处理以形成表面附着的官能团的颜料在喷墨油墨中与长链氧化胺组合以提供耐水性。 用于喷墨印刷的喷墨油墨包括:(a)载体,其包含(1)0至约30重量%的至少一种有机溶剂,和(2)0至约30重量%的至少一种水溶性油墨, 可溶性表面活性剂,和(3)约0.1〜10重量%的至少一种两性离子表面活性剂; (b)约1至20重量%的至少一种化学改性的水溶性高分子发色团,其包含具有共价连接到其上的官能团的颜料; 和(c)余量的水。 本发明的油墨随着两性离子表面活性剂的存在而提高了耐水性,而其它性能如脱皮,结垢和边缘敏锐度也不会受到两性离子表面活性剂的存在的不利影响。 实际上,通过两性离子表面活性剂的存在可以改善剥离和边缘的敏锐度。
