Abstract: The present invention is directed to a latex paint composition comprising polyunsaturated fatty acid containing additives derived from vegetable oils. In preferred embodiments, traditional water soluble additives such as thickeners, surfactants and dispersants are replaced with polyunsaturated fatty acid derivatives, adducts or polyunsaturated fatty acid containing polymers. The polyunsaturated fatty acid containing additives reduce or eliminate the need for traditional water soluble additives that lower the water resistance of the dry paint film. Additionally, the polyunsaturated fatty acid moieties are capable of oxidative crosslinking during the curing process, forming a dry paint film that is more durable and water-resistant than traditional latex paint compositions.
