Claims
- 1. An article comprising:
a stack of sheets, each sheet having a first side surface, an opposite second side surface, and a side edge, and wherein each sheet independently comprises: (a) a film, the film having a first side having a surface area, an opposite second side surface having a surface area; (b) a bonding layer having a first side having a surface area and an opposite second side having a surface area, wherein the bonding layer is bonded via its first side to the second side of the film such that at least a center of the surface area of the second side of the film is in contact with the bonding layer, wherein at least about 50 percent of the surface area of the second side of the film has the bonding layer bonded thereto; wherein each sheet is stacked upon another sheet such that except for a bottom sheet of the stack of sheets, the bonding layer of a sheet is in contact with the film of a sheet below; wherein at least a portion of the side edges of the sheets are disposed in a vertically staggered arrangement relative to one another thereby forming a vertically staggered side edge having a staircase configuration, wherein the vertically staggered side edge includes at least one indexing surface; and wherein the bonding layer of each sheet extends to the vertically staggered side edge; wherein a topmost sheet can be removed from the stack of sheets by pulling it away from the stack such that the sheet being removed from the stack as well as the sheets remaining with the stack do not delaminate; wherein the stack of sheets when subjected to a visual acuity test using a 3 meter Snellen eye chart allows an observer with 6 meter/6 meter vision to read a line on the eye chart which is indicative of about 6 meter/9 meter vision or better.
- 2. The article of claim 1 wherein when subjected to a visual acuity test using a 3 meter Snellen eye chart allows an observer with 6 meter/6 meter vision to read the line on the eye chart which is indicative of about 6 meter/6 meter vision or better.
- 3. The article of claim 1 wherein the stack of sheets is transparent.
- 4. The article of claim 1 wherein each sheet has a penetration resistance of at least about 0.5 kg.
- 5. The article of claim 1 which comprises at least about 3 sheets.
- 6. The article of claim 1 wherein the film has a thickness ranging from about 25 to about 4000 microns.
- 7. The article of claim 1 wherein the film comprises multiple layers.
- 8. The article of claim 1 wherein the release layer is present.
- 9. The article of claim 1 wherein the vertically staggered side edge is located at an edge of said article.
- 10. The article of claim 1 wherein the vertically staggered side edge is located at a corner of said article.
- 11. The article of claim 1 wherein the indexing surfaces have a shape selected from the group consisting of crescent shaped, rectangular, semicircular, and trapezoidal.
- 12. The article of claim 1 wherein the vertically staggered side edge is positioned at a corner of said article and wherein the indexing surfaces are crescent shaped having one concave edge and one convex edge.
- 13. The article of claim 1 wherein the vertically staggered side edge has a width ranging from about 0.5 mm to 25.0 mm.
- 14. The article of claim 1 wherein the vertically staggered side edge has a length ranging from about 1 cm to 50 cm.
- 15. The article of claim 1 wherein the vertically staggered side edge is in a staircase configuration.
- 16. The article of claim 1 wherein the vertically staggered side edge is in a reverse staircase configuration.
- 17. A construction comprising:
(i) an article comprising:
a stack of sheets, each sheet having a first side surface, an opposite second side surface, and a side edge, and wherein each sheet independently comprises: (a) a film, the film having a first side having a surface area, an opposite second side surface having a surface area; (b) a bonding layer having a first side having a surface area and an opposite second side having a surface area, wherein the bonding layer is bonded via its first side to the second side of the film such that at least a center of the surface area of the second side of the film is in contact with the bonding layer, wherein at least about 50 percent of the surface area of the second side of the film has the bonding layer bonded thereto; wherein each sheet is stacked upon another sheet such that except for a bottom sheet of the stack of sheets, the bonding layer of a sheet is in contact with the film of a sheet below; wherein at least a portion of the side edges of the sheets are disposed in a vertically staggered arrangement relative to one another thereby forming a vertically staggered side edge having a staircase configuration, wherein the vertically staggered side edge includes at least one indexing surface; and wherein the bonding layer of each sheet extends to the vertically staggered side edge; wherein a topmost sheet can be removed from the stack of sheets by pulling it away from the stack such that the sheet being removed from the stack as well as the sheets remaining with the stack do not delaminate; wherein the stack of sheets when subjected to a visual acuity test using a 3 meter Snellen eye chart allows an observer with 6 meter/6 meter vision to read a line on the eye chart which is indicative of about 6 meter/9 meter vision or better; and (ii) a substrate to which the article is bonded via the bonding layer of the bottom sheet.
- 18. The construction of claim 17 wherein the substrate comprises a material selected from the group consisting of glass, metal, plastic, painted surfaces, wood, fabric, wallpaper, ceramic, concrete, mirrored surfaces, plastic/glass laminates, and combinations thereof.
- 19. The construction of claim 17 wherein the substrate is part of a structure.
- 20. The construction of claim 19 wherein the structure is selected from the group consisting of windows, walls, partitions, signs, bill boards, artwork, buildings, elevators, vehicles, furniture, and doors.
- 21. The construction of claim 20 wherein the structure comprises a window;
- 22. The construction of claim 20 wherein the structure comprises a vehicle comprising a window; and wherein the article is bonded via the bonding layer of the bottom sheet to the window.
- 23. The construction of claim 22 wherein the vehicle is selected from the group consisting of buses, trains, and subways.
- 24. The article of claim 1 further including a release layer coated on the first side of the film; wherein each sheet is stacked upon another sheet such that except for a bottom sheet of the stack of sheets, the bonding layer of a sheet is in contact with the release layer of a sheet below.
