摘要:
An ink for ink-jet recording is provided, in which an amount of water X (% by weight) in the ink and a saturation viscosity Y satisfy Y≦4.5e0.09X. The saturation viscosity Y is a viscosity (mPa·s) obtained when an ink residual liquid, which is obtained by evaporating volatile components of the ink until a change in weight of the ink is less than 0.05 g/day per 50 g of ink under a condition of a temperature of 60° C. and a humidity of 40%, is cooled to a temperature of 25° C. in an environment of a humidity of 40%. X satisfies 50≦X≦75. The ink exhibits satisfactory jetting stability when the ink is normally used. Further, the ink is easily restored to give a normal jetting state even after undergoing an abnormal condition, for example, when the ink is left to stand without any nozzle cap.
