Manufacturing method of leather-like sheet |
| abstract |
A problem to be solved by the present invention is to provide a method of producing a leather-like sheet excellent in chemical resistance and discoloration resistance by using an aqueous urethane resin composition. The present invention relates to a urethane resin having a urea bond content of 0.3 mol / kg or less obtained by reacting a polyol (a1) containing a carboxyl group-containing polyol (a1-1), an aromatic polyisocyanate (a2) and a chain extender (a3) There is provided a process for producing a leather-like sheet characterized in that a film obtained by coating a substrate with an aqueous urethane resin composition containing a nonionic emulsifier (A), a nonionic emulsifier (B) and an aqueous medium (C) . The coating is preferably used as a skin layer and / or a top coating layer of a leather-like sheet. |
