摘要：
The instant invention is a polyurethane dispersion, method of producing the same, coated articles, and method for coating articles. The polyurethane dispersion according to the present inventions includes (a) one or more polyurethane units derived from one or more prepolymers wherein the one or more prepolymers comprise the reaction product of a mixture dissolved in dipropylene glycol dimethyl ether in the presence of one or more first surfactants with one or more isocyanates, wherein the mixture comprises one or more natural oil based polyols, and one or more adipate polyols, and optionally one or more short diols; and (b) water.
