摘要

To provide an aqueous inkjet ink composition excellent in glossiness and other ink properties and imparted with a higher viscosity without the use of a tackifier, an acrylic resin emulsion for an aqueous inkjet ink is provided, which contains a particulate acrylic resin having an acid value of 1 to 100 mgKOH/g, wherein an acid-group-containing monomer is present at a content mole ratio (As) in surface regions of particles of the particulate acrylic resin and present at a content mole ratio (At) in the overall acrylic resin particles as measured with a 1 H spin diffusion time of 5 ms, and a ratio (As/At) of the content mole ratio (As) to the content mole ratio (At) is not less than 9.
