Abstract
A polyisocyanate composition is produced by reaction of bis(isocyanatomethyl) cyclohexane with trimethylolpropane, and contains a trimethylolpropane-monomolecular-body obtained by reaction of three molecules of bis(isocyanatomethyl) cyclohexane with one molecule of trimethylolpropane, and a trimethylolpropane-bimolecular-body obtained by reaction of five molecules of bis(isocyanatomethyl) cyclohexane with two molecules of trimethylolpropane; and the molar ratio of trimethylolpropane-monomolecular-body relative to trimethylolpropane-bimolecular-body (trimethylolpropane-monomolecular-body/trimethylolpropane-bimolecular-body) contained in the polyisocyanate composition is 1.5 or more and 4.5 or less.
