Abstract
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.
Claims17
A label adapted to remain opaque in wet condition for pressure sensitive application, said label comprising:
- an outer layer of facestock for receiving printed indicia;
- a first opacifying adhesive layer and a second opacifying adhesive layer,
- wherein said first opacifying adhesive layer underlies said facestock,
- wherein said second opacifying adhesive layer underlies said first opacifying adhesive layer,
- wherein said first opacifying adhesive layer includes a first adhesive component and a first pigment component in a 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 said first opacifying adhesive layer in said pressure sensitive application,
- wherein said second opacifying adhesive layer includes a second adhesive component and a second pigment component in a 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 said second opacifying adhesive layer in said pressure sensitive application;
- and
- a liner underlying said second opacifying adhesive layer.
A method of preparation of an opacifying adhesive composition which is adapted to remain opaque in wet condition for pressure sensitive label application, said method comprising the steps of:
- mixing a proportionate amount of an adhesive component and pigment component with agitation;
- and
- wherein said opacifying adhesive does not cause any unacceptable loss of peel adhesion or tack of the adhesive component in pressure sensitive application.
