Abstract
In a polyurethane dispersion obtained by water-dispersing a polyurethane resin, the polyurethane resin is a reaction product obtained by reacting at least a polyisocyanate component with an active hydrogen group-containing component containing an active hydrogen compound having an anionic group, a ratio of the total moles of a urethane group and a urea group is 1.5 mol or more with respect to 1 kg of the polyurethane dispersion, and the carbonate ion concentration is 700 ppm or less with respect to the polyurethane dispersion.
