Abstract
A two-component polyurethane composition comprising a polyisocyanate and an emulsion polymer having greater than 2.2% of hydroxy groups in the emulsion polymer and comprising structural units of a polymerizable surfactant, a first hydroxy-functional monomer, an acid monomer and/or a salt thereof, an additional monoethylenically unsaturated nonionic monomer, and optionally a second hydroxy-functional alkyl (meth)acrylate; the two-component polyurethane composition providing improved alcohol resistance without compromising both acid and alkali resistance.
