Abstract
The present invention is directed to aqueous coating compositions, such as paints, containing a film-forming latex polymer and a reactive surfactant and/or a low VOC humectant. The reactive surfactant, a polyglycerol ester or ether of an unsaturated fatty acid, reduces or eliminates the need for traditional water-soluble additives that lower the water resistance of the dry coating. Additionally, the reactive surfactants of the invention are capable of oxidative cross-linking during the curing process, forming a dry film that is more durable and water-resistant than traditional latex paint composition. The low VOC humectant polyglycerol, isosorbide, or a derivative of isosorbide can replace at least in part traditional humectants such as propylene glycol which contribute to VOCs, while maintaining an effective open time for application of the aqueous coating compositions.
