Abstract
An aqueous inkjet ink composition comprising a pigment, a pigment-dispersing resin, resin fine particles (A), water, and hydrophilic solvents (B), the resin fine particles (A) being formed by emulsion polymerizing ethylenically unsaturated monomers including: 20% to 80% by weight of an aromatic ethylenically unsaturated monomer (C) that does not have an ionic functional group; 0.6% to 6% by weight of water-soluble ethylenically unsaturated monomers (F) consisting of 0.5% to 3% by weight of a sulfonic acid group-containing ethylenically unsaturated monomer (D) and 0.1% to 3% by weight of a nonionic water-soluble ethylenically unsaturated monomer (E); and 0.1% to 10% by weight of a crosslinkable ethylenically unsaturated monomer (G), and the hydrophilic solvents (B) including a glycol-based solvent (H) and an ethylene glycol ether-based solvent (I) is provided.
