Abstract
A polymeric film having a translucent first layer of polymeric material, a transparent second layer of polymeric material on at least one surface of the first layer, and an adherent layer comprising an acrylic resin on the surface of the second layer remote from the first layer is disclosed. Both the first and second layers are preferably formed of biaxially oriented polyethylene terephthalate. The first layer contains an inorganic filler opacifying agent. The polymeric film is particularly suitable for use as an upper sheet in a re-usable label employing the "magic slate" principle.
