Abstract:
The present invention provides a polyisocyanate composition wherein the composition is obtained from an aliphatic diisocyanate unit including 1,6-diisocyanatohexane, and has an isocyanurate group, a uretdione group, a uretonimine group, and an iminooxadiazinedione group, and the molar ratio of the uretonimine group to the isocyanurate group is 0.0010 to 0.0050, and the molar ratio of the iminooxadiazinedione group to the isocyanurate group is 0.00050 to 0.30.
