Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a two step curable polyisocyanate having a radiation curable group for a crosslinkage photochemically initiated and a blocked NCO group thermally cured. SOLUTION: This blocked polyisocyanate has at least one radiation curable group and at least one structural unit represented by formula (II) (wherein R1, R2and R3are each independently hydrogen or a 1-4C alkyl group or a cycloalkyl group, R4is a 1-4C alkyl group, a 6-10C cycloalkyl group or a 7-14C aralkyl group, and x is an integer of 1-5).
