Abstract:
The aqueous, substantially volatile organic compound (VOC)-free coating compositions of the invention include an acrylic latex and a vinyl acetate-ethylene latex including from about 10 to about 90 weight percent of a vinyl acetate-ethylene polymer, based on total weight of acrylic polymer and vinyl acetate-ethylene polymer, having a Tg from about −20 to about 20 degrees Celsius; and from about 10 to about 90 weight percent of an acrylic polymer, based on the total weight of acrylic polymer and vinyl acetate-ethylene polymer, the acrylic polymer comprising, in polymerized form, at least one ethylenically unsaturated (meth)acrylic monomer and from about 0.01 to about 10 weight percent, based on total weight of the acrylic polymer, of an acetoacetate moiety containing monomer, where the acrylic polymer has a Tg of from about −20 to about 20 degrees Celsius.
