Beschreibung
Zusammenfassung:	The present invention provides a polyisocyanate curing agent including a structural unit derived from a diisocyanate, a structural unit derived from a polyester polyol, and a structural unit derived from the following general formula (1), wherein a content of the isocyanate group is 5.0 to 20.0% by mass and a molar ratio between a urethane group derived from a polyalkylene glycol alkyl ether and a urethane group derived from the polyester polyol is 0.03 to 2.5,(in formula (1), R1is an alkylene group having 1 to 4 carbon atoms, R2is an alkyl group having 1 to 4 carbon atoms, and an average number of n is 4.0 to 20.0).
