Abstract:
The ink for ink jet recording includes a sparingly water-soluble alkanediol, a resin, and a coloring material, wherein the content of the coloring material is from 1 to 3% by mass based on the total mass of the ink, the surface tension is from 21 to 25 mN/m, and the thixotropic index (TI) represented by the following formula (1), as determined at a time point when its content becomes 40% by mass based on the total mass before the evaporation of the ink by the evaporation of the ink, is from 2 to 110: TI=η(1 s−1)/η(1000 s−1) (1).
