    • An aqueous ink for inkjet printing which includes a pigment, a compound represented by formula (1) and/or a compound represented by formula (2): R1—O—(CH2CH2O)n—H  (1) R1—O—(CH2CH2O)m—R2  (2) wherein R1 and R2 are each an aliphatic group having 2 to 5 carbon atoms or an alicyclic group having 3 to 5 carbon atoms, and n and in 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/cm2.
    • 用于喷墨印刷的水性油墨,其包含颜料,由式(1)表示的化合物和/或由式(2)表示的化合物:R1-O-(CH2CH2O)n-H(1)R1-O-(CH2CH2O )m-R2(2)其中R1和R2各自为具有2至5个碳原子的脂族基团或具有3至5个碳原子的脂环族基团,n和n各自的平均加成摩尔数为6至9, 和含水量为50〜65重量%的水。 由式(1)表示的化合物和由式(2)表示的化合物的总含量为10〜30重量%。 水性油墨在印刷和印刷密度以及储存稳定性之后的卷曲预防性优异。 在通过一次通过印刷在普通纸上使用水性墨水进行喷墨打印图像的方法中,喷射到普通纸的单位面积上的水性墨水中的含水量被调节在0.2至1.0mg / cm 2之内。
