Abstract

An adhesive article and a method of making the adhesive article are described. The adhesive article includes a facestock film having a first surface, a second surface and end edges wherein the second surface has a plurality of recesses formed therein that provide a path for fluid egress to at least one end edge; and a continuous layer of adhesive adhered to the second surface of the facestock film. The adhesive layer can compress, collapse or flex into the recesses of the embossed surface in response to a force to create a path for fluid egress.

Claims

1. An adhesive article comprising:

a facestock film having a first surface, a second surface and end edges;

a release liner; and

a continuous layer of adhesive having a thickness ranging from about 10 to about 125 microns and a coat weight of about 10 to about 50 grams per square meter and having a first surface and a second surface, wherein the first surface of the adhesive layer is adhered to the second surface of the facestock film,

the release liner having a release surface releasably adhered to the second surface of the adhesive layer,

wherein the second surface of the facestock film has a plurality of recesses having a depth ranging from about 1 mil to about 30 mils and a width ranging from about 0.5 mils to about 250 mils that are free of adhesive and form a path to at least one end edge of the facestock film that provide a path for fluid egress, and

upon application of the adhesive article to a surface of a substrate, the adhesive layer is capable of filling the plurality of recesses thereby creating a complementary path for air egress at an interface between the adhesive layer and the surface of the substrate.

2. The adhesive article of claim 1 wherein the plurality of recesses form a pattern.

3. The adhesive article of claim 2 wherein the pattern comprises a plurality of parallel lines.

4. The adhesive article of claim 2 wherein the pattern comprises a plurality of intersecting lines.

5. The adhesive article of claim 2 wherein the pattern comprises a plurality of interconnected shapes.

6. The adhesive article of claim 1 wherein the recesses are at least partially filled with a compressible foam.

7. The adhesive article of claim 1 wherein the facestock film comprises a multilayer film.

8. The adhesive article of claim 1 wherein the facestock film comprises a decorative wall covering or a graphic film.

9. The adhesive article of claim 1 wherein the adhesive layer comprises a pressure sensitive adhesive or a heat activated adhesive.

10. The adhesive article of claim 1 wherein the facestock film has a thickness of about 0.0127 mm to about 0.254 mm.

11. The adhesive article of claim 1 further comprising a print layer disposed on the first surface of the facestock film.

12. The adhesive article of claim 11 wherein the print layer comprises a radiation curable ink.

13. The adhesive article of claim 1 wherein the release surface of the release liner has a textured surface.

14. The adhesive article of claim 1 wherein the release liner has non-adhesive material forms adhered to or embedded into the release surface.

15. The adhesive article of claim 1 wherein the recesses are formed by embossing the second surface of the facestock.

16. The adhesive article of claim 1 wherein the recesses are formed by imprinting protrusions on the second surface of the facestock which delineate recesses on the second surface of the facestock.
