Absorbent binder coating

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.
