An ink and ink set characterized in that both a combination of a specific wetting agent, a penetrating agent, and a water-soluble organic solvent and use of a surfactant, particularly a fluorine surfactant are enabled by using a water dispersion in which polymer fine particles contain a coloring material. Even when a plain paper is printed at high speed by an ink-jet recording by using this ink and ink set, the ink and ink set can realize a pigment ink for ink-jet recording, an ink set, an ink-jet recording method, an ink cartridge, and a recorder which have an excellent ejection stability and an excellent preservability, and provide (1) good color tone, (2) high image density, (3) a recorded image free of unsharpness near a character or image and feathering and high in sharpness, (4) less boundary color bleedings between different colors, (5) an image adaptable to both-side printing and causing less strike-throughs, and (6) image fastness such as water resistance and light resistance.
一种墨水和墨水组,其特征在于,通过使用含有着色材料的聚合物微粒的水分散体,实现了特定润湿剂、渗透剂和水溶性有机溶剂的组合以及表面活性剂(尤其是氟表面活性剂)的使用。即使使用这种墨水和墨水组通过喷墨记录高速打印普通纸,该墨水和墨水组也能实现喷墨记录用颜料墨水、墨水组、喷墨记录方法、墨盒和记录器,这些墨水和墨水组具有出色的喷出稳定性和出色的保存性,并能提供 (1) 良好的色调、(2) 图像密度高;(3) 所记录的图像在字符或图像附近没有不清晰现象,没有羽化现象,清晰度高;(4) 不同颜色之间的边界渗色少;(5) 图像可适应双面印刷,造成的击穿现象少;(6) 图像牢度高,如防水和耐光。
