<p>PROBLEM TO BE SOLVED: To obtain an aqueous gloss ink composition readily re-dispersible a pigment without generating a hard cake even preserving for a long period of time, having excellent writing property and useful for a brush pen, etc., by including a pearl pigment, etc., a polyolefin-based emulsion and water. SOLUTION: This ink composition contains at least (A) preferably 2.0-30 wt.% (based on total weight of the composition) of a pearl pigment such as titanium oxide and/or a metal powder pigment such as an aluminum powder pigment, (B) preferably 0.1-10 wt.% of a polyolefin-based emulsion such as a nonionic emulsion and (C) water. Preferably, a particle diameter of the component A is <=100μm and a using weight ratio of the pearl pigment/the metal powder pigment is (1/0.01)-(1/0.6).</p> |
