The problem to be solved by the present invention is to provide an aqueous urethane dispersion that does not excessively penetrate into the base fabric and is excellent in peel strength and peelability. The present invention provides an aqueous urethane resin dispersion, which contains urethane resin (A), water (B), and a crosslinking agent (C), characterized in that the urethane resin (A) ) The viscosity at 50°C is in the range of 15,000 Pa·s to 34,000 Pa·s, the viscosity at 100°C is in the range of 1,000 Pa·s to 10,000 Pa·s, and the viscosity at 150°C is 100 Pa·s. ～1,300 Pa·s range. In addition, the present invention provides a synthetic leather having an adhesive layer formed from the aqueous urethane resin dispersion. In addition, the present invention provides a method for manufacturing the synthetic leather. |
