Waterborne polyurethane dispersions for preparing polyurethane foam for synthetic leather and synthetic leather articles prepared with the same

A waterborne polyurethane dispersion for preparing polyurethane foam for synthetic leather, wherein the waterborne polyurethane dispersion is derived from:

• (1) from 40 wt % to 60 wt %, based on the total weight of the waterborne polyurethane dispersion, of a prepolymer,
• wherein the prepolymer is derived from the reaction of reactants comprising:
• from 20 wt % to 35 wt % of at least one aromatic isocyanate compound having at least two isocyanate groups, from 20 wt % to 45 wt % of an ethylene oxide-capped polyether triol, from 1 wt % to 20 wt % of at least one polyether diol, and from 20 wt % to 40 wt % of at least one polyester diol, based on the total weight of the prepolymer;
• (2) from 35 wt % to 55 wt % of water, based on the total weight of the waterborne polyurethane dispersion;
• and
• (3) from 0.5 wt % to 5 wt % of surfactant, based on the total weight of the waterborne polyurethane dispersion.
