WÄSSRIGE TINTE FÜR TINTENSTRAHLDRUCKER

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≤4.5e<0.09X>. 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 DEG C and a humidity of 40 %, is cooled to a temperature of 25 DEG 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.
