摘要： PROBLEM TO BE SOLVED: To provide an aqueous resin composition which ensures the good appearance of a coating film and superior compounding stability with an unsaturated polymerizable monomer polymer, a method for manufacturing the same, and a metallic coating material.SOLUTION: The aqueous resin composition and the metallic coating material are characterized in that an unsaturated polymerizable monomer polymer (A) is emulsified with a cationic group-containing polyurethane resin (B). The method for producing the aqueous resin composition includes: a step of dispersing in water a solution containing an unsaturated polymerizable monomer (a) and a cationic group-containing isocyanate group-terminated urethane prepolymer (b); a step of emulsifying a cationic group-containing polyurethane resin (B) by chain elongation of the cationic group-containing isocyanate group-terminated urethane prepolymer (b) with water and/or a polyamine; and a step of yielding an unsaturated polymerizable monomer polymer (A) by polymerizing the unsaturated polymerizable monomer (a).
