Abstract

PURPOSE: To prepare a water-based ink composition having excellent evaporation resistance, storage stability, and water-resistance of written images, and suitable for writing utensils, stamp, printing, ink-jet recording, etc., by using a specific alkanol- amine salt together with a dye and water, as a component of the composition.
CONSTITUTION: Pref. 5W30wt% of an alkanol-amine salt of 2-pyrrolidone-5-carboxylic acid (e.g. 2-pyrrolidone-5-carboxylic acid triethanolamine salt) is added to an ink composition containing a dye (e.g. pref. 0.1W30wt% of a direct dye such as Deep-Black RBL) and if necessary, an additive such as ethylene glycol.
EFFECT: The addition of said alkanol-amine salt enables the dissolution of a part of even a hardly water-soluble acidic-, direct-, basic- and spirit-soluble dye, and improves the water-resistance of the written images.
