    摘要： Provided herein is an aqueous ink, which is excellent in both image density and fixing ability irrespective of the kind of a recording medium even when the volume of an ink droplet is small and has such excellent properties that white stripes are not caused even when high-speed recording is conducted. The aqueous ink comprises at least water, a water-soluble organic solvent, a water-insoluble coloring material, a surfactant and a poor medium for the water-insoluble coloring material and/or a salt. The dynamic surface tension of the aqueous ink at a lifetime of 50 milliseconds determined by a maximum bubble pressure method is higher than 47 mN/m, and the dynamic surface tension at a lifetime of 5,000 milliseconds determined by the maximum bubble pressure method is 38 mN/m or lower.

    摘要： An inkjet ink contains at least one coloring material selected from the group of C. I. Direct Violet 107, C. I. Acid Red 14, C. I. Acid Red 52, C. I. Acid Red 87, C. I. Acid Red 289 and C. I. Reactive Red 180, and a coloring material including a compound expressed by general formula (I): wherein in the formula (I), each M independently represents hydrogen, an alkali metal, ammonium, or an organic ammonium. The ratio of the content in the inkjet ink of the compound expressed by general formula (I) to the total content of coloring materials in the inkjet ink is in the range of 15.0% by mass or more to 40.0% by mass or less.
