Zusammenfassung:An ink composition contains (component A) a high-molecular-weight polymerization initiator having a weight-average molecular weight of equal to or greater than 1,000, (component B) a polymerizable compound, and (component C) a colorant, in which the component A has an acylphosphine oxide structure, and the acylphosphine oxide structure is linked to a main chain or a core of the component A on the side of an acyl group thereof.
