Abstract: A water-borne road marking paint composition which includes a chelating agent capable of chelating iron ions to form a substantially colorless complex is provided. A road marking produced from the traffic paint of the present invention substantially reduces or prevents yellowing of white road marking from iron and iron compound debris strewn on the road surfaces. A method of reducing or preventing yellowing of a newly-applied road marking on a road surface of a water-borne road marking paint is also disclosed. The method comprises incorporating in the water-borne road marking paint a chelating agent capable of chelating iron ions to form a substantially colorless complex. Further reduction of yellowing of the road marking is observed when a pigment dispersant is incorporated in the water-borne road marking paint.

Abstract: The present invention relates to the preparation of water based coating compositions having extended storage stability. The composition includes separately stored polymeric binder component and a crosslinking component.These components are mixed prior to application over surfaces, such as, road surfaces. The polymeric binder component includes an anionically stabilized binder polymer having at least one reactive functional pendent moiety, or a blend of the binder polymer with a polyfunctional amine.
