Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polyisocyanate composition which has low viscosity, storage stability, and moisture stability and exhibits good mixing stability with a main agent when used as an aqueous coating.SOLUTION: The polyisocyanate composition is obtained from an aliphatic diisocyanate containing 1,6-diisocyanatohexane and contains an isocyanurate group, a uretdione group, a uretonimino group, and an iminooxadiazinedione group. The molar ratio of the uretonimino group to the isocyanurate group is 0.0010-0.0050. The molar ratio of the iminooxadiazinedione group to the isocyanurate group is 0.00050-0.30. The polyisocyanate composition has a phosphorus concentration of 1-50 ppm in plasma emission spectroscopic analysis.SELECTED DRAWING: None 【課題】低粘度であり、貯蔵安定性及び湿気安定性を有し、水性塗料として用いたときの主剤との混合安定性が良い、ポリイソシアネート組成物を提供すること。【解決手段】１，６−ジイソシアナトヘキサンを含む脂肪族ジイソシアネートから得られ、イソシアヌレート基、ウレトジオン基、ウレトンイミノ基、及びイミノオキサジアジンジオン基を含有し、前記ウレトンイミノ基／前記イソシアヌレート基のモル比率が０．００１０〜０．００５０であり、前記イミノオキサジアジンジオン基／前記イソシアヌレート基のモル比率が０．０００５０〜０．３０であり、かつ、プラズマ発光分光分析におけるリン濃度が１〜５０ｐｐｍである、ポリイソシアネート組成物。【選択図】なし
