Claims
- 1. A method of making an adhesive article comprising the steps of:
providing a construction comprising a facestock with front and back surfaces and a layer of adhesive having an upper and lower surface, wherein the upper surface of the adhesive layer is in adhesive contact with the back surface of the facestock layer; applying a pattern of a non-adhesive material to the lower surface of the adhesive layer; and embedding the non-adhesive material into the adhesive layer.

- 15. The method of claim 1 wherein the embedding step comprises winding the material so that the patterned lower surface of the adhesive is in adhesive contact with the front surface of the facestock.
- 16. The method of claim 15 wherein the front surface of the facestock has a release surface.
- 17. The method of claim 1 wherein the adhesive comprises a pressure sensitive adhesive.
- 18. The method of claim 1 wherein the adhesive comprises a heat-activated adhesive.
- 19. The method of claim 1 further comprising applying randomly distributed non-adhesive particulate material onto the lower surface of the adhesive layer prior to the embedding step.
- 20. The method of claim 2 further comprising applying randomly distributed non-adhesive particulate material onto the release surface of the release liner prior to the embedding step.
- 21. The method of claim 20 further comprising at least partially embedding the randomly distributed non-adhesive particulate material into the release surface of the release liner prior to the embedding step.
- 22. The method of claim 2 wherein the release surface of the release liner has a non-adhesive material printed thereon.
- 23. The method of claim 22 wherein the non-adhesive material printed on the release surface of the release liner is embedded into the release surface.
- 24. The method of claim 1 further comprising applying a second layer of adhesive to the front surface of the facestock.
- 25. The method of claim 24 wherein a pattern of a non-adhesive material is applied to the second adhesive layer.
- 26. A method of making an adhesive article comprising the steps of:
providing a construction comprising a release liner having a release surface and a front surface, and a layer of adhesive having an upper and lower surface, wherein the lower surface of the adhesive layer is in releasable contact with the release surface of the release liner; applying a pattern of a non-adhesive material to the upper surface of the adhesive layer; and embedding the non-adhesive material into the adhesive layer.
- 27. The method of claim 26 further comprising applying a facestock to the upper surface of the adhesive layer.
- 28. The method of claim 26 wherein the applying step and the embedding step occur simultaneously.
- 29. The method of claim 26 wherein the pattern comprises a plurality of dots, lines or combinations thereof.
- 30. The method of claim 26 wherein the step of applying the pattern of non-adhesive material comprises printing, vacuum metalization or sputtering.
- 31. The method of claim 26 wherein the applying step comprises flexographic printing.
- 32. The method of claim 26 wherein the non-adhesive material comprises a UV curable ink.
- 33. The method of claim 26 wherein the non-adhesive material is embedded below the plane of the surface of the adhesive.
- 34. The method of claim 26 wherein the release liner has a Sheffield roughness of greater than about 50.
- 35. The method of claim 26 wherein the release surface of the release liner has a matte finish.
- 36. The method of claim 26 wherein the release surface of the release liner has a patterned finish.
- 37. The method of claim 26 wherein the non-adhesive material comprises a porous non-adhesive material.
- 38. The method of claim 37 wherein the porous non-adhesive material comprises an elastomer.
- 39. The method of claim 26 wherein the release surface of the release liner has a non-adhesive material printed thereon.
- 40. The method of claim 39 wherein the non-adhesive material printed on the release surface of the release liner is embedded into the release surface.
- 41. The method of claim 26 wherein the embedding step comprises applying a second release liner to the upper surface of the adhesive layer.
- 42. The method of claim 26 wherein the front surface of the release liner has a release coating thereon and one surface of the release liner has a higher release value than the other.
- 43. The method of claim 42 wherein the embedding step comprises winding the material so that the patterned upper surface of the adhesive is in adhesive contact with the front surface of the release liner.
- 44. The method of claim 26 wherein the embedding step comprises applying a facestock to the upper surface of the adhesive layer.
- 45. The method of claim 26 wherein the adhesive comprises a pressure sensitive adhesive.
- 46. The method of claim 26 wherein the adhesive comprises a heat-activated adhesive.
- 47. The method of claim 26 wherein the release surface of the release liner has randomly distributed non-adhesive particulate material applied thereto.
- 48. The method of claim 26 wherein the release surface of the release liner has randomly distributed non-adhesive particulate material embedded therein.
