Abstract
The present invention provides a blocked polyisocyanate composition comprising a blocked polyisocyanate formed through blocking at least a part of isocyanate groups possessed by a polyisocyanate derived from one or two or more diisocyanates selected from the group consisting of an aliphatic diisocyanate and an alicyclic diisocyanate with an active methylene-based compound comprising a malonic acid diester, wherein a specific molar ratio calculated from contents (mol %) of isocyanurate groups, iminooxadiazinedione groups, uretdione groups, and allophanate groups is 0.05 or more and 0.60 or less.
