Patent ID: 7491778

Claim:
An article at least partially coated comprising at least one surface of said article at least partially coated with a superabsorbent polyacrylate polymer coating comprising: (i) at least one water-soluble superabsorbent polyacrylate polymer precursor in aqueous solution, which cures, when the coating is applied to said at least one surface, to form a superabsorbent polyacrylate polymer; (ii) a viscosity-modifying agent which is a polymeric solution or dispersion; and (iii) a film forming binder in an aqueous solution compatible with said superabsobent polyacrylate polymer precursor and said viscosity-modifying agent; wherein said film forming binder is selected from the group consisting of polyesters, polyurethanes, epoxies, acrylic latex, a styrene-butadiene latex, and mixtures thereof and wherein said superabsorbent polyacrylate polymer coating absorbs from about 50 to about 400 times its initial dry weight of water when immersed in an aqueous environment.
