Abstract
A water-based ink for ink-jet recording includes a coloring agent, water, and a water-soluble organic solvent. In the water-based ink after drying, a phase (δ) obtained by a tan δ measured at about 25° C. is constantly about 45 degrees or more. In other words, the phase (δ) never becomes less than about 45 degrees at a strain amount of about 0.1% to about 100%.
