ABSTRACT:
The present invention provides compositions that enable excellent hardness in coating applications, the compositions containing one or more copolymer having as copolymerized units one or more acrylic monomer with a phosphorus acid-functional group, a polymeric side chain containing multi-acid functional groups, a salt thereof, or a combination thereof, one or more polyurethane dispersion made from a high molecular weight polyol, and one or more coalescent having a normal boiling point of 190° C. or higher. The compositions may be ambient curable.
