Abstract:
An aqueous ink ensuring less blurring and high color formation on plain paper, satisfactory color formation and fixing property on special paper and excellent ejection stability is realized by using a microcapsule of a colorant encapsulated with a polymer and rendered dispersible in water and specifying the amount of the aromatic ring in the polymer to be from 20 to 70 wt % of the polymer.
