Abstract
Electrostatically charged graphic sheets are additionally provided with a preapplied activatable adhesive. Such sheets may be oriented on a display substrate using the electrostatically induced adhesion, and more securely fastened to the display substrate using the activatable adhesive.
Claims26
A graphic sheet comprising a film having a top and bottom surface, said film having an electrostatic charge, said bottom surface further comprising a preapplied activatable adhesive, said electrostatic charge being sufficient to support said sheet on a vertical clean insulated surface and said activatable adhesive having an exposed surface.
A graphic sheet comprising a film having a top and bottom surface, said film having an electrostatic charge, said bottom surface of said film further comprising a preapplied pressure sensitive adhesive with a removable release liner, said electrostatic charge being sufficient to support said sheet on a vertical clean insulated surface.
A graphic sheet comprising a film having a top and bottom surface, said film having an electrostatic charge sufficient to support said sheet on a vertical clean insulated surface, said bottom surface of said film further comprising preapplied activatable adhesive.
A method of applying a graphic sheet to a display substrate, comprising:
- a) providing a graphic sheet comprising a film having a top and bottom surface, said film having an electrostatic charge, said bottom surface of said film further comprising a preapplied pressure sensitive adhesive with a removable release liner, said electrostatic charge being sufficient to support said sheet on a vertical clean insulated surface;
- b) applying the bottom surface of the film to the intended location on the display substrate, thereby temporarily adhering the sheet to the display substrate through the electrostatic charge of the film;
- c) orienting said sheet on the display substrate;
- d) removing the release liner from the pressure sensitive adhesive, thereby exposing said adhesive;
- and
- e) applying said exposed adhesive to the display substrate, thereby securely adhering the sheet to the display substrate.
