Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a dispersion of a polyurethane polymer excellent in strength properties, heat resistance, low temperature flexibility and weather resistance. SOLUTION: There are provided a polyurethane dispersion and products produced therefrom wherein the dispersion contains a polyurethane prepolymer produced from the a reaction of an excess of a polyisocyanate with an isocyanate-reactive molecule, and the isocyanate comprises (i) trans-1,4-bis(isocyanatomethyl)cyclohexane or (ii) an isomeric mixture of two or more of cis-1,3-bis(isocyanatomethyl)cyclohexane, trans-1,3-bis(isocyanatomethyl)cyclohexane, cis-1,4-bis(isocyanatomethyl)cyclohexane and trans-1,4-bis(isocyanatomethyl)cyclohexane (wherein the isomeric mixture contains at least about 5 wt.% of the trans-1,4-bis(isocyanatomethyl)cyclohexane).
