Abstract
PURPOSE: To prepare an ink having excellent water resistance, capable of preventing the discoloration of dye, and useful for writing utensils, printing, recording instrument, etc., by compounding a copolymer of ethyleneimine and ethylene oxide to a direct or acid dye, a water-soluble organic solvent, and water.
CONSTITUTION: The objective watr-based ink is prepared by mixing (A) a direct dye and/or a an acid dye, (B) a water-soluble organic solvent such as ethylene glyco l, (C) water, and (D) a copolymer of ethyleneimine and ethylene oxide, e.g. at room temperature. The amounts of (B), (C) and (D) are pref. 1W40wt%, 40W85%, and 0.5W10wt%, respectively.
