ABSTRACT:
Compositions useful as coating compositions comprise the reaction product of a polyurethane polyol which contains acidic carboxyl groups with an alkylenimine. Particularly desirable coatings are produced by further combining the imine-modified polyurethane polyols with aminoplast resins. The compositions are characterized by improved pigment wetting properties and provide coatings having improved low temperature, flexibility and increased adhesion.
