Abstract
A polyisocyanate composition having at least one isocyanate compound selected from an aliphatic isocyanate and an alicyclic isocyanate as a skeleton, wherein an average value of a total number of isocyanate groups blocked with a blocking agent and not blocked with a blocking agent per polyisocyanate molecule is 2 or more, and among the isocyanate groups in the polyisocyanate composition, 1 mol % or more and 99 mol % or less are blocked with a blocking agent, and the like.
Claims6
A primary cured film obtained by curing a polyisocyanate composition including at least one isocyanate compound selected from the group consisting of an aliphatic isocyanate and an alicyclic isocyanate as a skeleton, and an active hydrogen-containing composition, comprising
- at least one functional group X selected from the group consisting of a urethane group, a urea group, and an amide group produced by curing the active hydrogen-containing compound and the polyisocyanate composition,
- an active hydrogen group, and
- an isocyanate group blocked with a blocking agent.
