<p>PURPOSE:To provide a water ink which has excellent long-term stability, water resistance, dye developability and dry resistance when left standing in air over a long period of time, by blending a specified tert, amine compd. or a triazine derivative with an aq. soln. of a water-soluble dye. CONSTITUTION:A compd. of formula I (wherein 1<=a<=5; 1<=b<=5; 1<=c<=5) or a compd. of formula II (wherein 1<=n<=5) and optionally a solvent such as polyhydric alcohol, glycol, or glycol ether, a preservative, etc. are blended with an aq. soln. of a dye such as a water-soluble acid dye, direct dye or basic dye to obtain the desired ink. An example of the compd. of formula I is a compd. of formula III. An example of the compd. of formula II is a compd. of formula IV. These compds. are used in a quantity of pref. 0.5-3wt% based on that of the ink.</p> |
