ABSTRACT:
A water-in-oil dispersed ink comprising:
(A) a water-insoluble dispersion medium comprising 20% by weight--50% by weight of a water-insoluble polar solvent of an aromatic alcohol and/or an aliphatic glycol phenyl ether, 0.5% by weight--5.0% by weight of a water-insoluble organic amine, and 3% by weight--30% by weight of an oil-soluble dye, all percentages being based on the total weight of the ink; and
(B) a particulate dispersion phase including a dispersion stabilizing phase comprising a polyhydric alcohol that is formed on the surface of dispersed particles, the particulate dispersion phase comprising 20% by weight--50% by weight of the polyhydric alcohol, and a water-based dispersoid comprising 3% by weight--20% by weight of water, 0.3% by weight--2.0% by weight of a cross-linking acrylic acid polymer, and 0.5% by weight--4.0% by weight of triethanol amine, all percentages being based on the total weight of the ink, and wherein the dispersed particles are uniformly dispersed in the dispersion medium.
