The polyvalent alcohol monoalkyl ether preferably has a vapor pressure not greater than 0.1 mm Hg at 20.degree. C. The ink exhibits superior recording properties (signal responsiveness, stability in liquid form, discharge stability, continuous recording ability over long periods of time, and ink discharge stability after use has been suspended for long periods of time), fluid stability, preservation stability, adherence to recording materials, quick drying, printing quality and low odor, thus being an excellent ink for various types of ink jet recording.
