An aqueous ink for inkjet printing which includes a pigment-containing polymer particle and/or a self-dispersible pigment, a compound represented by formula (1):
CH3-O-(CH2CH2O)n-R1 (1)
wherein R1 is hydrogen atom, an aliphatic group having 1 to 6 carbon atoms, or an alicyclic group having 3 to 6 carbon atoms, and n is an average molar number of addition of 6 to 20, and water in a content of 50 to 65% by weight. The content of the compound represented by formula (1) is 10 to 30% by weight. The aqueous ink is excellent in the curl prevention after print, curl prevention after its storage and print density as well as in the storage stability and jetting stability. In a method of inkjet-printing images on plain paper by one-pass print, the water content in the aqueous ink which is jetted onto unit area of the plain paper is regulated within 0.2 to 1.0 mg/cm2.
