Claims23
An article comprising:
- a first substrate;
- and
- an adhesive layer disposed on the first substrate, the adhesive layer comprising a first adhesive region comprising a first adhesive and a second adhesive region comprising a second adhesive, wherein the first adhesive is different from the second adhesive and the first adhesive region forms an indicia.
A method of making an article comprising a step of disposing an adhesive layer on a first substrate, the adhesive layer comprising a first adhesive region comprising a first adhesive and a second adhesive region comprising a second adhesive, wherein the first adhesive is different from the second adhesive and the first adhesive region forms an indicia.
A method of using an article comprising steps of:
- providing an adhesive laminate comprising an adhesive layer disposed on a first substrate, the adhesive layer comprising a first adhesive region comprising a first adhesive and a second adhesive region comprising a second adhesive, wherein the first adhesive is different from the second adhesive and the first adhesive region forms an indicia;
- applying the adhesive laminate to a second substrate such that the adhesive layer is positioned between the first substrate and the second substrate;
- and
- separating at least a portion of the first substrate from at least a portion of the second substrate, wherein the separating provides a tamper evident feature.
