PROBLEM TO BE SOLVED: To provide a self-emulsifying polyisocyanate which has excellent defoaming properties and water dispersion stability, has a sufficient pot life in an aqueous dispersion state, and has good physical properties after curing. A water-based paint and a water-based adhesive are provided. SOLUTION: An active hydrogen group-containing ionic surfactant in which a compound (a1) containing an ethylenically unsaturated bond and an active hydrogen group and an ionic surfactant (a2) containing an ethylenically unsaturated bond are bonded by radical polymerization. Self-emulsification obtained by reacting an agent (A), an active hydrogen group-containing nonionic surfactant (B), and optionally an active hydrogen group-containing compound (D), and an organic polyisocyanate (C) And a water-based paint and a water-based adhesive using the same. |
