Summary: | To provide an inkjet ink that exhibits excellent wettability even on a non-ink absorbent medium, while being excellent in drying properties.SOLUTION: An ink includes a coloring agent, an organic compound other than the coloring agent and water. The organic compound contains, for instance, 1,5-pentanediol and a compound d in which an R1 in a formula (1) is a hydrocarbon group of C5-C6. If a content of the 1,5-pentanediol with regard to 100 pts.mass of the ink is (e) pts.mass and an entire content of the compound d is (d) pts.mass, the (d) is larger than 0.3, and a relation of 1<(e)/(d)≤50 is satisfied.SELECTED DRAWING: None
【課題】インク非吸収性メディア上においても良好な濡れ性を示し、且つ、乾燥性にも優れたインクジェット用インクを提供する。【解決手段】本発明のインクは、着色剤、上記着色剤を除く有機化合物、及び水を含有する。上記有機化合物は、例えば、1,5-ペンタンジオール、及び下記式(1)におけるR1がC5-C6の炭化水素基である化合物dを含み、インク100質量部中における1,5-ペンタンジオールの含有量を(e)質量部、化合物dの総含有量を(d)質量部としたとき、(d)が0.3より大きく、且つ、1<(e)/(d)≦50の関係を満たす。TIFF2023080084000025.tif29134【選択図】なし |
