Aqueous dispersion of urethane resin, leather sheet, and method for producing leather sheet |
| abstract |
The present invention provides an aqueous dispersion of a urethane resin (X) that uses a nonionic group-containing compound (a1) as a raw material, the aqueous dispersion being characterized in that the usage percentage of the compound (a1) having a nonionic group is at most 5 mass% with respect to the total mass of raw materials constituting the urethane resin (X), the content of an anionic emulsifier (Y1) in the aqueous dispersion is at most 7 parts by mass with respect to 100 parts by mass of the urethane resin (X), and an organic solvent is not included during a production process. In addition, the present invention provides a leather sheet characterized in that a coagulation of the aqueous dispersion of the urethane resin is present in a fiber substrate. The leather sheet is preferable when the coagulation of the aqueous dispersion of the urethane resin is present in the fiber substrate. |
