Water-dispersible polyisocyanate, aqueous polyurethane resin composition, and article

Abstract

A water-dispersible polyisocyanate contains an isocyanate group and a sulfone group. The water-dispersible polyisocyanate contains a reaction product of a polyisocyanate component and a hydrophilic active hydrogen component. The polyisocyanate component contains a bis(isocyanatomethyl)cyclohexane derivative. The hydrophilic active hydrogen component contains a sulfone group-containing active hydrogen compound. The bis(isocyanatomethyl)cyclohexane derivative contains an allophanate derivative and an isocyanurate derivative. The allophanate derivative is contained in an amount of 25% by mass or more and 75% by mass or less relative to the total amount of the allophanate derivative and the isocyanurate derivative.
