Abstract
Abstract A resin composition comprising (A) a polyisocyanate having an isocyanurate ring obtained by reacting at least one diisocyanate selected from alkylene diisocyanates, cycloalkylene diisocyanates and aralkylene diisocyanates with a diol having 10 to 40 carbon atoms or with a polyester polyol containing 12-hydroexystearic acid as an essential component in the presence of an isocyanuration catalyst, and (B) a nonpolar organic solvent. The composition is useful, for example, as a point, an adhesive or a molding material.
