<P>PROBLEM TO BE SOLVED: To provide inkjet ink capable of substantially improving print image quality by virtue of excellent ink ejecting stability. <P>SOLUTION: The inkjet ink includes a color material, a resin, water, a solvent in the range of 10 wt.% or more and 35 wt.% or less and a fluorine- or silicon-containing surfactant and has viscosity in the range of 20 cP or less. In the inkjet ink, the dynamic surface tension γ<SB POS="POST">30</SB>after 30 seconds by a plate method is in the range of 25 mN/m or more and 35 mN/m or less and the difference between the dynamic surface tension γ<SB POS="POST">30</SB>and the dynamic surface tension γ<SB POS="POST">600</SB>after 600 seconds satisfies γ600-γ30 ≤-1 mN/m. <P>COPYRIGHT: (C)2013,JPO&INPIT |
