ABSTRACT:
Shelf-stable, one-package aqueous latices, which are curable with or without the application of heat, consist essentially of an alkaline-curable, self-crosslinking emulsion polymer, selected organic metal salts, and water. The alkali, alkaline earth, or heavy metal salts of C.sub.1 -C.sub.6 organic acids (e.g., sodium acetate) are post-added to th polymer emulsion or present during the polymerization. The polymer typically comprises about 90-99.9% by weight of one or more vinyl polymerizable monomers (e.g., acrylates, vinyl esters, and ethylene) and 0.1-10% by weight of a polymerizable non-ionic or cationic self-crosslinking monomer containing halohydrin groups (e.g., 3-chloro-2-hydroxypropyl (meth)acrylate or the reaction product of epichlorohydrin and N,N-dimethylaminopropyl methacrylamide or methacrylate).
