Provided is a binder composition and its use in aqueous based paints and coatings and other applications. The binder composition comprises: a polyurethane dispersion containing water and a polyurethane polymer, wherein the polyurethane polymer is prepared by reacting a nitroalcohol compound, a polyol compound, a polyisocyanate compound, and optionally chain extenders, wherein the nitroalcohol compound is of formula I, wherein R, R1, and Z are as defined herein.
