This invention relates to urethane acrylic hybrid polymer dispersion with robust dry/wet adhesion and the basecoats prepared therefrom for automotive applications. In this system, the polyurethane dispersion (PUD) prepolymer is based on a combination of polyols and aliphatic diisocyanates. The acrylic portion is based on (meth)acrylated monomers. A combination of this hybrid polymer dispersion and other resins having defined glass transition temperature (T.sub.g) values, organic and/or inorganic rheology modifiers, and different additives including pigment, dispersant, and defoamer are used to prepare waterborne basecoats having modified appearance and performance. The final coatings show excellent dry/wet adhesion to the primer for automotive applications.
