Abstract
Abstract A pressure sensitive product is disclosed which comprises: (a) a plastic film; (b) a layer of pressure sensitive adhesive attached to the film, optionally, with a backing material therebetween, said layer of adhesive containing non-leafing metallic flakes; and (c) optionally, a release liner attached to the surface of the adhesive. After application of bonding pressure, the product exhibits superior adhesion as compared to a control product not containing the metallic flakes.
