Abstract: An ink composition comprises at least a coloring agent coated with a water-insoluble polymer and resin particles. The water-insoluble polymer is a polymer obtained by a solution polymerization process using at least a polymerizable unsaturated monomer and a polymerization initiator. The coloring agent coated with the water-insoluble polymer is a coloring material obtained by a phase inversion emulsification process in which, after the water-insoluble polymer is dissolved in an organic solvent, at least the coloring agent and water are added thereto, followed by mixing. The organic solvent is removed to perform dispersion in an aqueous system. The resin particles are a polymer obtained by an emulsion polymerization process using at least a crosslinking agent. The average particle size of the resin particles is from 20 to 80 nm.
