Abstract
PURPOSE: To provide a water-based ink having specific pH value and extremely excellent water resistance, and resistant to the dissolution of the dye even by immersing in water after writing, by compounding a specific coloring material having sulfonanilide structure, a water-soluble organic solvent, and water.
CONSTITUTION: The objective ink is prepared by mixing (A) a coloring material having sulfonailide structure of formula (Pc is metal-containing phthalocyanine residue; a is 2W4; b is 0W2; a+b is ≤4; x is Na or K), (B) a water-soluble organic solvent (e.g. ethylene glycol) and (C) water, and adjusting the pH of the mixture at ≥10 with a strong base such as sodium hydroxide. The amounts of the components (A)W(C) are pref. 0.5W20wt%, 5W50wt% and 50W95wt% of the ink, respectively. The component (A) is, e.g. copper phthalocyanine sulfonic acid anilide derivative, nickel phthalocyanine sulfonic acid anilide derivative, etc.
