    摘要: The water-dispersed polyurethane composition of the present invention comprises a polyisocyanate component (a), a polyol component (b), and water as the essential components, wherein, at least, an isocyanate compound represented by general formula (I) below is used as the polyisocyanate component (a). The water-dispersed polyurethane composition of the present invention is excellent in adhesiveness, water resistance, corrosion resistance, heat resistance, weather resistance, water repellency, oil repellency, and the like, and can be suitably used as paint for surface-treated steel plates. wherein R1 represents an alkyl group having 10 to 30 carbon atoms, R2 represents —N═C═O or —NH—C(═O)C—O— R1, and A represents a residue other than two —N═C═O groups derived from a diisocyanate.
