  • Patent number: 5861188
    Abstract: The present invention is directed to traffic paint compositions, which dry faster than conventional waterborne traffic paints and to a method of producing traffic paint road markings made therefrom. The traffic paint composition of the present invention includes a blend of an anionically stabilized polymer binder, a polyfunctional amine polymer having an amine and an acid functionality therein and an amount of volatile base sufficient to raise the pH of the composition to a point where essentially all of the polyfunctional amine polymer is in a non-ionic state. The traffic paint composition of the present invention further provides improved storage stability.
