Patent ID: 7115321

Claim:
A combination of an absorbent binder coating and a substrate, the combination comprising: an absorbent binder coating at least partially covering a substrate, wherein the absorbent binder coating includes a reaction product of about 15–99.8% by mass of monoethylenically unsaturated units; about 0.1–20% by mass polyacrylate ester units that include an alkoxysilane functionality; and about 0.1–75% by mass polymer units selected from polyolefin glycol units, polyolefin oxide units, or combinations thereof; wherein the reaction product includes a copolymer of at least the monoethylenically unsaturated units and the polyacrylate ester units; the copolymer establishes intimate contact with the substrate; the copolymer crosslinks after establishing intimate contact with the substrate; the copolymer assumes a final shape on the substrate to form the coating; and the coating absorbs water vapor at 22° C. and 50% relative humidity at a rate of at least 4 weight percent per hour, for at least two hours.
