Abstract

Composite layer comprising a plurality of longitudinal, generally parallel first zones comprised of a first polymeric material each encapsulated in a second polymeric material. There are at least 10 longitudinal first zones per cm.

Claims

1. A composite layer comprising a plurality of longitudinal, generally parallel first zones comprised of a first polymeric material each encapsulated in a second polymeric material, wherein there are at least 10 longitudinal first zones per cm.

2. The composite layer of claim 1, wherein each first zone has a maximum dimension perpendicular to the longitudinal direction of not greater than 1 mm.

3. The composite layer of claim 1, wherein each first zone has a center point, wherein there is a length between two center points separated by a second zone, wherein there is an average of said lengths, where the lengths between two center points separated by a second zone are within 20 percent of the average of said lengths.

4. The composite layer of claim 1, wherein the first polymeric material comprises first adhesive material.

5. A privacy article comprising the composite layer of claim 1.

11. The composite layer of claim 1, wherein, by volume, the ratio of the second polymeric material to the first polymeric material is at least 5:

1.

12. The composite layer of claim 4, wherein the first adhesive material has a first release.

13. The composite layer of claim 1, wherein the second polymeric material comprises second adhesive material.

14. The composite layer of claim 13, wherein the second adhesive material has a second release.

15. An assembly comprising a document having indicia on a first surface thereof and a privacy article of claim 5, wherein said privacy article is positioned on said first surface.

6. A composite layer comprising:

a first plurality of longitudinal, generally parallel first zones comprised of a first polymeric material each encapsulated in a second polymeric material, wherein there are at least 10 longitudinal first zones per cm, wherein each first zone has a center point, wherein there is a length between two center points separated by a second zone, and wherein there is an average of said lengths; and

a second plurality of longitudinal, generally parallel first zones comprised of the first polymeric material each encapsulated in the second polymeric material, wherein there are at least 10 longitudinal first zones per cm wherein there is a length between two center points separated by a second zone, and wherein there is an average of said lengths,

wherein there is an average length two center points separated by a second zone for the composite layer of the average of said averages lengths two center points separated by a second zone for the first and second pluralities, and wherein there is a third zone comprising the first or second polymeric material separating the first and second pluralities having a width wider than said average length two center points separated by a second zone for the composite layer.

7. The composite layer of claim 6, wherein each first zone has a maximum dimension perpendicular to the longitudinal direction of not greater than 1 mm.

8. The composite layer of claim 6, where the lengths between two center points separated by a second zone are within 20 percent of the average of said lengths between two center points separated by a second zone for the composite layer.

9. The composite layer of claim 6, wherein the first polymeric material comprises first adhesive material.

10. A privacy article comprising the composite layer of claim 6.

16. The composite layer of claim 6, wherein, by volume, the ratio of the second polymeric material to the first polymeric material is at least 5:

1.

17. The composite layer of claim 9, wherein the first adhesive material has a first release.

18. The composite layer of any of claim 6, wherein the second polymeric material comprises second adhesive material.

19. The composite layer of claim 18, wherein the second adhesive material has a second release.

20. An assembly comprising a document having indicia on a first surface thereof and a privacy article of claim 10, wherein said privacy article is positioned on said first surface.
