The present invention is a urethane emulsion obtained by stirring a urethane prepolymer having a carboxyl group, a neutralizing agent, and a water-containing urethane prepolymer composition for the purpose of providing a urethane emulsion that becomes a cured product having excellent water repellency. The polyisocyanate compound in which a polymer has two or more isocyanate groups, the siloxane containing polyol compound which has two or more hydroxyl groups, and dimethylsiloxane, and / or the fluorine-containing polyol which has two or more hydroxyl groups, and a fluoroethylene, and a hydroxyl group It is a urethane emulsion obtained by making a carboxyl group-containing compound which has two or more and a carboxyl group react at a specific ratio. |
