Title: POLYISOCYANATE COMPOSITION, COATING COMPOSITION, WATER-BASED COATING COMPOSITION, AND COATED BASE
Abstract:
The present invention provides a polyisocyanate composition obtained by reacting one or more hydrophilic compounds with a raw-material polyisocyanate composition which includes a polyisocyanate having an aliphatic diisocyanate unit. The polyisocyanate composition contains isocyanurate groups, uretdione groups, uretonimino groups, and iminooxadiazinedione groups, wherein the molar ratio of the uretonimino groups to the isocyanurate groups is 0.0010-0.0050 and the molar ratio of the iminooxadiazinedione groups to the isocyanurate groups is 0.00050-0.30.
