Title: POLYISOCYANATE COMPOSITION AND COATING COMPOSITION
Abstract:
A polyisocyanate composition is derived from at least one diisocyanate selected from the group consisting of an aliphatic diisocyanate and an alicyclic diisocyanate and has an isocyanurate structure, wherein, in spectra measured by gel permeation chromatography, there is detected a polymer which is derived from a 1-nylon compound having an UV absorption in a region corresponding to a diisocyanate 11-mer or higher, and the ratio of the height (B) of the UV absorption peak for the polymer derived from the 1-nylon compound to the height (A) of the UV absorption peak for a compound corresponding to a diisocyanate trimer, i.e., (B)/(A), is 0.1 to 30 inclusive.
