Abstract: Disclosed are aqueous, storage-stable, crosslinkable polymer compositions comprising: (a) an aqueous dispersion of a an acrylic polymer component containing certain carbonyl-containing functional-groups; (b) a nitrogen-containing compound having at least two carbonyl-reactive nitrogen groups; and (c) optionally, co-solvents, pigments, fillers, dispersants, wetting agents, anti-foam agents, UV absorbers, antioxidants, biocides, and stabilizers. Such compositions are useful as coatings or binders in coating compositions, or as adhesives.
