<p>An aqueous ink for inkjet printing which includes a pigment, a compound represented by formula (1) and/or a compound represented by formula (2):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒR 1 -O-(CH 2 CH 2 O) n -H€ƒ€ƒ€ƒ€ƒ€ƒ(1)
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒR 1 -O-(CH 2 CH 2 O) m -R 2 €ƒ€ƒ€ƒ€ƒ€ƒ(2)
wherein R 1 and R 2 are each an aliphatic group having 2 to 5 carbon atoms or an alicyclic group having 3 to 5 carbon atoms, and n and m are each an average molar number of addition of 6 to 9, and water in a content of 50 to 65% by weight, The total content of the compound represented by formula (1) and the compound represented by formula (2) is 10 to 30% by weight. The aqueous ink is excellent in the curl prevention after print and print density as well as in the storage stability. In a method of inkjet-printing images using the aqueous ink 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/cm 2 .</p> |
