Patent ID: 8163384

Claim:
An adhesive-containing labelstock useful in reducing microbial populations comprising: (A) a polymer film substrate comprising a terpolymer prepared from a mixture comprising (i) an olefin, (ii) at least one copolymerizable ethylenically unsaturated organic acid or ester, and (iii) carbon monoxide, said substrate having a first surface and a second surface, and (B) an adhesive layer underlying the second surface of the substrate, and (C) a polymeric topcoat layer having a first surface and a second surface wherein the second surface is in contact with the first surface of the polymer film substrate, and wherein at least one of the substrate, adhesive layer or topcoat layer contains an effective amount of an antimicrobial composition which comprises at least one metal chlorite and at least one solid inorganic hydrophilic material capable of reacting with the metal chlorite when exposed to water.
