Disclosed is a polyurethane dispersion capable of forming a polyurethane layer excellent in a dispersed state and excellent in gas barrier properties and adhesion, and a polyurethane laminate obtained by using the polyurethane dispersion. An active hydrogen group-containing compound containing a polyisocyanate component containing xylylene diisocyanate and / or hydrogenated xylylene diisocyanate, a diol having 2 to 6 carbon atoms, a low molecular weight polyol having 3 or more valences, and a hydrophilic group. It is obtained by reacting an isocyanate group-terminated prepolymer obtained by reacting a polyol component with a chain extender containing a primary amino group or an alkoxysilyl compound having a primary amino group and a secondary amino group. Polyurethane dispersion in which the polyurethane resin is dispersed in water. [Selection figure] None |
