Abstract: A waterborne polyurethane dispersion is provided. The waterborne polyurethane dispersion is prepared by using a tri-functionality polyether polyol as part of the polyols for forming the prepolymer and a hydrophilic amino siloxane co-chain extender, and can exhibit superior performance properties such as enhanced color fastness, improved low temperature stability, good anti-stickiness, bally flex resistance, anti-abrasion and mechanical properties. A laminated synthetic leather article prepared with said waterborne polyurethane dispersion as well the method for preparing the synthetic leather article are also provided.
