Abstract
A film-based article including a film layer having first and second major sides, an adhesive layer comprising a first surface adjacent to the second major side of the film and a second surface opposite the first surface, wherein the second surface of the adhesive layer comprises a structured surface comprising a plurality of outwardly extending protrusions, each having a base, wherein the bases of the plurality of protrusions comprise at least approximately 6 percent of a total surface area of the second surface of the adhesive layer, and an ink layer applied to the first major side of the film layer at an ink laydown of at least 100 percent.
Claims12
A film-based article comprising:
- a film layer having first and second major sides;
- an adhesive layer comprising a first surface adjacent to the second major side of the film and a second surface opposite the first surface, wherein the second surface of the adhesive layer comprises a structured surface comprising a plurality of outwardly extending protrusions, each having a base, wherein the bases of the plurality of protrusions comprise at least 6 percent up to 25% of a total surface area of the second surface of the adhesive layer, and wherein the second surface of the adhesive layer further comprises at least one channel;
- an ink layer applied to the first major side of the film layer at an ink laydown of at least 100 percent, and
- an overlaminate film over the ink layer.
A film-based article comprising:
- a film layer having first and second major sides;
- an adhesive layer comprising a first surface adjacent to the second major side of the film and a second surface opposite the first surface, wherein the second surface of the adhesive layer comprises a structured surface comprising:
- a plurality of outwardly extending protrusions, each having a base, wherein the bases of the plurality of protrusions comprise at least 6 percent up to 25% of a total surface area of the second surface of the adhesive layer;
- and an array of channels;
- and
- a solvent-based ink coating applied to the first major side of the film layer, wherein the solvent-based ink coating has an ink laydown of at least 100 percent, and
- an overlaminate film over the ink coating.
A method of applying a film-based article to a substrate, comprising the steps of:
- positioning a film-based article adjacent to an outer surface of a substrate, wherein the film-based article comprises:
- a film layer having first and second major sides;
- an adhesive layer comprising a first surface adjacent to the second major side of the film and a second surface opposite the first surface, wherein the second surface of the adhesive layer comprises a structured surface comprising a plurality of outwardly extending protrusions, each having a base, wherein the bases of the plurality of protrusions comprise at least 6 percent up to 25% of a total surface area of the second surface of the adhesive layer, and wherein the second surface of the adhesive layer further comprises at least one channel;
- a release liner adjacent to the second surface of the adhesive layer;
- and
- an ink layer applied to the first major side of the film layer at an ink laydown of at least 100 percent, and an overlaminate film over the ink layer;
- removing the release liner from the second surface of the adhesive layer;
- and
- applying the second surface of the adhesive layer to the outer surface of the substrate.
