POLYISOCYANATE COMPOSITION, SOLAR CELL MEMBER COVERING MATERIAL, SOLAR CELL MEMBER WITH COVERING LAYER, MICROCAPSULE, AND INK BINDER

摘要

A polyisocyanate composition is obtained by reaction between bis(isocyanatomethyl)cyclohexane and trimethylolpropane, which comprises a trimethylolpropane monomolecular body obtained from a reaction of three molecules of bis(isocyanatomethyl)cyclohexane with a molecule of trimethylolpropane and a trimethylolpropane bimolecular body obtained from a reaction of five molecules of bis(isocyanatomethyl)cyclohexane with two molecules of trimethylolpropane, wherein the content molar ratio of the trimethylolpropane monomolecular body to the trimethylolpropane bimolecular body (trimethylolpropane monomolecular body/trimethylolpropane bimolecular body) is 1.5 to 4.5.
