(57) [Problem] To provide an ink composition for realizing a printed image having excellent light fastness. SOLUTION: The light resistance of the ink composition can be improved by adding a polymer having an ultraviolet absorbing ability and / or a light stabilizing ability and a film forming ability to the ink composition as fine particles. Therefore, with the coloring material, An ink composition comprising water, a water-soluble organic solvent, and polymer fine particles, wherein the polymer fine particles have a film-forming ability and a UV-absorbing ability and / or a light stabilizing ability. By using such an ink composition, a light-fast image can be realized. |
