ABSTRACT:
A water based coating composition provides a stain resistant layer which adheres well to a substrate and is resistant to chemical attack by common household cleaning solvents such as isopropyl alcohol. The coating composition has a very low volatile organic compound content, thus providing an environmentally desirable alternative to organic solvent based coatings. The low volatile organic compound content of the composition substantially or completely eliminates the problems and expenses associated with solvent recovery for meeting chemical emission standards, and the potential for human exposure to solvent vapor is substantially eliminated or significantly reduced. The coating composition is aqueous based and incorporates a crosslinkable acrylic polymer latex, an amino resin crosslinking agent and a crosslinking catalyst. The polymer, crosslinking agent and catalyst are dispersed and/or solubilized in an aqueous medium. The coating composition is particularly well suited for application to flexible vinyl chloride polymer substrates to produce upon curing and drying a stain resistant, easily cleanable laminate. The stain resistant laminates can be advantageously used in the manufacture of wallcoverings, luggage exteriors, upholstery, vehicle interior and seat coverings, golf bags and other sporting goods, table cloths, and other similar applications.
