Abstract
A water base ink for ink-jet recording contains a self-dispersing type pigment, glycol ether, and water. In the glycol ether, the number of carbon atoms of an ethylene oxide moiety is not less than 8, and the solubility in water at 25° C. is not less than 1%. The ink reduces the blurring of a recorded image which would be otherwise caused by the feathering on the paper surface. The ink is excellent in drying performance on the paper surface, and the ink makes it possible to stably disperse the pigment.
