Abstract
The invention relates to an improved water-based polymer coating composition comprising a polymer resin, water and surfactant. As an improvement over prior water-based polymer coating compositions an anionic and/or nonionic surfactant is present in an amount effective to plasticize the coating formed from the composition. A water-based polymer coating composition of the invention is also substantially free from cosolvents. The invention also relates to a method of coating a substrate and a substrate which has been coated with a coating formulation of the invention.
