Provided is an active energy beam-curable water-based resin composition which is obtained by reaction of an acrylic resin (A) obtained by copolymerizing essential starting materials, namely an acrylic monomer (a1) including a polyoxyalkylene group, an acrylic monomer (a2) including a hydroxyl group, and an acrylic monomer (a3) other than the acrylic monomer (a1) and the acrylic monomer (a2); a polyisocyanate compound (B); and (meth)acrylate (C) having a hydroxyl group, followed by dispersion of the reaction product in an aqueous medium. The active energy beam-curable water-based resin composition has excellent storage stability, provides a good appearance of the cured coating film thereof, and exhibits high adhesion with a substrate even after immersion in hot water, and the composition is thus suitable for use in an active energy beam-curable water-based coating. |
