<p>PROBLEM TO BE SOLVED: To provide a visual-angle-dependent multicolor ink composition which can give a written line or coating film having an interference color (transition color) of a visual-angle-dependent multicolor type accompanied by a brightness feeling with brilliant glittering without being affected by the color of a substrate. SOLUTION: This ink composition contains a visual-angle-dependent multicolor pigment, a shear-thinning agent, a water-soluble organic solvent, and water. The visual-angle-dependent multicolor pigment comprises an aluminum substrate layer having an optically reflective plane with a flat surface and a titanium dioxide covering layer covering the aluminum substrate layer and causing light interference.</p> |
