Abstract: PROBLEM TO BE SOLVED: To easily produce the subject resin having excellent weather resistance and alkali resistance in contrast with conventional urethane resins without using ordinary synthetic solvents by dispersing a polyurethane produced in the absence of solvent in water under specific condition and radically polymerizing the obtained aqueous dispersion. SOLUTION: A polyurethane having a number-average molecular weight of <=30,000 is produced by reacting a polyol with an organic polyisocyanate without using a solvent. The polyurethane is dispersed in water in the presence of a hydroxyl-containing organic solvent (preferably a solvent containing isopropyl alcohol) and an unsaturated monomer and the obtained aqueous dispersion of the polyurethane solution is radically polymerized. A stable dispersion is produced by using polyethylene glycol as the polyol. The amount of the hydroxyl-containing organic solvent is preferably 1-50 wt.% based on the polyurethane. The amount of the unsaturated monomer is preferably selected to give a water-based resin having a polyurethane content of 5-95 wt.%.
