Abstract

PURPOSE: To provide an aq. yellow ink which has good color tone, solubility and water resistance and is suitable for use in marking pens, containing a specified dye or dyes.
CONSTITUTION: There is provided an aq. yellow ink containing dyes of formula I and/or formula II (wherein Q is a radical of formula III or IV). Since these dyes have four or more amino gp., the dyes are easily bonded to the hydroxyl gp. of a cellulose. Further, the dyes have such a property that the dyes are easily agglomerated by sizing agents (acidic) contained in papers. Thus, the water resistance of the ink is improved. These dyes are used in an amount of pref. 0.5W20wt% based on the total weight of the ink.
