PURPOSE:To obtain the titled ink having a improved setting point and quick drying property of the ink, by compounding a water-soluble dye with polyhydric alcohols, an aliphatic monohydric alcohol and water at specific ratios to give a surface tension higher than a specific level. CONSTITUTION:The objective ink is produced by compounding (A) 0.5-0.7wt.% water-soluble ink, (B) 70-30wt.% polyhydric alcohols (e.g. glycerol), (C) 5-20wt.% aliphatic monohydric alcohol (e.g. methanol) and (D) water and adjusting the surface tension to >=45dyne/cm at 20 deg.C. |
