PROBLEM TO BE SOLVED: To obtain an aqueous ink composition for inkjet recording that gives reliable printing performance and gives a recorded image having chroma equal to or superior to that of the corresponding dye-based ink prepared by using a water-soluble dye and has durability to a special paper and an ordinary paper. SOLUTION: The aqueous ink composition for inkjet recording comprises water as the main solvent, at least one vat dye and at least one micelle-forming component. The micelle-forming component forms a micelle in an aqueous solution having a pH of higher than 8 wherein the micelle has an average diameter of greater than 20 nm to smaller than 150 nm as measured by photon correlation spectrometry. |
