PROBLEM TO BE SOLVED: To provide an aqueous polyurethane resin dispersion (UE) having good film forming properties and excellent mechanical properties of a dry film, and excellent durability such as water resistance and solvent resistance. And A polyurethane resin having a carboxyl group in the molecule (U 0), having reactivity with a carboxyl group, the difference between the SP value of the polyurethane resin (U 0) having a carboxyl group is 3 or less A polyurethane resin aqueous dispersion (UE) containing a polyurethane resin obtained by reacting a compound (P) having an SP value and water.
