PROBLEM TO BE SOLVED: To provide a polyisocyanate composition which is excellent in heat resistance, allows reduction of the solvent amount as a coating composition and enables formation of a coating film excellent in smoothness and sharpness.SOLUTION: A polyisocyanate composition is obtained by using at least 1,6-diisocyanatohexane and has mol ratio of iminooxadiazine dione structure/isocyanurate structure of 6.0/100 to 20/100 and a mol ratio of uretdione structure/isocyanurate structure of 0.1/100 to 5.0/100, measured byC-NMR. |
