Graffiti and/or environmental protective article having removable sheets, substrates protected therewith, and a method of use

A construction comprising:

• (i) an article comprising:
• a stack of sheets, wherein each sheet independently comprises:
• (a) a film, the film having a first side having a surface area and an opposite second side 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 with respect to each sheet the first side of the film is not bonded to a bonding layer of the same sheet;
• (c) 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;
• 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 can allow an observer with 6 meter/6 meter vision to read a line on the eye chart which is indicative of about 6 meter/12 meter vision or better;
• and
• (ii) a substrate to which the article is bonded via the bonding layer of the bottom sheet.

A method comprising the steps of:

• (a) applying an article comprising:
• a stack of sheets, wherein each sheet independently comprises:
• (i) a film, the film having a first side having a surface area and an opposite second side having a surface area;
• (ii) 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 with respect to each sheet the first side of the film is not bonded to a bonding layer of the same sheet;
• (iii) 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;
• 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 can allow an observer with 6 meter/6 meter vision to read a line on the eye chart which is indicative of about 6 meter/12 meter vision or better;
• to a substrate via the bonding layer of the bottom sheet of the article;
• (b) allowing the topmost sheet of the article to be damaged;
• (c) removing the damaged topmost sheet of the article by gripping the sheet and pulling it away from the stack, in a manner such that neither the sheet being removed nor the stack of sheets which remains delaminates, in order to expose a lower sheet of the article which thence becomes the topmost sheet of the article.

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 polyester film, the polyester 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 polyester film such that at least a center of the surface area of the second side of the polyester film is in contact with the bonding layer, wherein at least about 50 percent of the surface area of the second side of the polyester film has the bonding layer bonded thereto;
• (c) an optional release layer coated on the first side of the polyester 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 polyester film or release layer, if present, of a sheet below;
• 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 can allow 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.
