Opaque Adhesives in Wet Condition for Label Application

摘要

Various opacifying adhesive compositions are described. The adhesives exhibit relatively high levels of opacity in wet conditions while maintaining acceptable adhesive properties. Also described are label assemblies and labeled containers using such adhesives. Related methods of use and preparation are also described.

1. A label adapted to remain opaque in wet condition, said label comprising:
an outer layer of facestock for receiving printed indicia; at least one opacifying adhesive layer underlying said facestock,
wherein said opacifying adhesive layer comprises an adhesive component and a pigment component in proportion sufficient to maintain opacity when exposed to an aqueous environment and a peel adhesion of at least 1 N/inch and a loop tack of at least 2 N/inch of the opacifying adhesive layer in a pressure sensitive application; and a liner, underlying said opacifying adhesive layer.
