PROBLEM TO BE SOLVED: To provide an ink composition improved with dispersing property and fastness, and excellent in dispersion stability and re-dissolvability by using a dispersion in which a coloring matter is included by a cross-linked hydrophobic block segment in a dispersed polymer. SOLUTION: This ink composition containing an amphiphilic block polymer including the coloring matter and a solvent is provided with that the amphiphilic block polymer compound including the coloring matter forms a dispersion by using the hydrophobic block segments as inside core parts and the hydrophobic block segments are cross-linked.
