ABSTRACT:
Known laminates can be used to apply graphics to glass panels to present an etched or sand-blasted appearance. Such graphics, which have been cut from a decorative polymeric film of a laminate, can be applied more easily, quickly, and with greater precision when the cover sheet of the laminate is a vented transparent polymeric sheet which bears a layer of vented removable pressure-sensitive adhesive that has been pressed against the graphics. Coextensive with each of the graphics is a layer of aggressive pressure-sensitive adhesive by which the graphics can be applied to a glass panel while wet with a detergent/alcohol/water solution that permits them to be repositioned by a user who can see the graphics through the vented transparent sheet. Positioning is enhanced when the vents are perforations arranged in an orderly pattern such as a rectangular grid.
