Abstract
The invention provides an ink composition, which is improved in dispersibility and fastness properties and is excellent in dispersion stability and re-solubility owing to dispersed particles in which a coloring material is included by a crosslinked hydrophobic block segment in a dispersing polymer. The ink composition contains an amphiphilic block polymer compound, in which a coloring material is included, and a medium, wherein the amphiphilic block polymer compound, in which the coloring material is included, forms a dispersed particle having the hydrophobic block segment as an internal core part, and the hydrophobic block segment is crosslinked.
