Abstract
An article includes a plurality of stacked sheets. Each sheet includes a film having a first side, with a print receptive or primed layer, and a second side, with an optional release treated layer; and a bonding layer that is coated at 100% solids on the first side of the film to releasably attach a second side of a film of an overlying sheet to the first side of an underlying sheet. Each sheet is stacked upon another sheet such that except for a topmost sheet of the stack the bonding layer is in contact with the second side of a film of an overlying sheet. The bonding layer of the topmost sheet defines an outer surface of the stack that protects the topmost sheet of the stack from environmental damage.
