Abstract
An ink and ink set characterized in that both a combination of a specific wetting agent, penetrating agent, and water-soluble organic solvent and use of surfactant, particularly fluorine surfactant are enabled by using water dispersion in which polymer fine particles contain coloring material. Even when plain paper is printed at high speed by 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, ink cartridge, and recorder which have an excellent ejection stability and excellent preservability, and provide (1) good color tone, (2) high image density, (3) recorded image free of unsharpness near character or image and feathering and high in sharpness, (4) less boundary color bleedings between different colors, (5) image adaptable to both-side printing and causing less strike-throughs, and (6) image fastness such as water resistance and light resistance.
