摘要： An object of the present invention is to provide an ink composition which can provide an image having excellent glossy texture to various recording media, particularly to a glossy recording medium, is decreased in bronzing phenomenon, and is also good in fixing property and scratch resistance such as gloss change. The invention relates to an ink composition containing at least a coloring agent coated with a water-insoluble polymer as a coloring material and a resin emulsion as an additive, wherein the weight average molecular weight of the water-insoluble polymer is from 50,000 to 150,000, and wherein the resin emulsion comprises a resin comprising a monomer component of the same kind as the monomer component constituting the water-insoluble polymer and having a weight average molecular weight of 1.5 to 4 times that of the water-insoluble polymer; and an ink composition containing at least a coloring agent coated with a water-insoluble polymer and resin particles, wherein the water-insoluble polymer is a polymer obtained by a solution polymerization process using at least a polymerizable unsaturated monomer and a polymerization initiator, wherein 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, and the organic solvent is removed to perform dispersion in an aqueous system, and wherein the resin particles are a polymer obtained by an emulsion polymerization process using at least a crosslinking agent.
