<p>Disclosed is an aqueous polyurethane resin which is obtained by a reaction between a prepolymer having a terminal isocyanate group and a chain extender. The prepolymer having a terminal isocyanate group is obtained by reacting at least a polyisocyanate, which contains not less than 50% by mole of isocyanate groups of 1,4-bis(isocyanatomethyl)cyclohexane relative to the total mole number of the isocyanate groups, a high-molecular-weight polyol, and an active hydrogen compound containing a hydrophilic group.</p> |
