1. An ink composition comprising:
coloring particles that include a quinacridone solid solution pigment including two or more types of quinacridone-based compounds, a synergist including a basic group, and a high-molecular weight vinyl polymer; a water-soluble polymerizable compound; a polymerization initiator; and water,wherein the synergist includes a structural moiety derived from at least one type selected from the group consisting of a quinacridone derivative, a triazine derivative, an acridone derivative, and an anthraquinone derivative. |
