Non-limiting examples of pressure sensitive adhesives useful with the present invention include those adhesives described in U.S. Pat. Nos. Re. 24,906 (Ulrich); 2,973,826; Re. 33,353; 3,389,827; 4,112,213; 4,310,509; 4,323,557; 4,732,808; 4,917,929; 5,141,790 (Calhoun et al.); 5,229,207 (Paquette et al.); and 5,296,277 (Wilson et al.) and European Publication 0 051 935, the disclosures of which are incorporated by reference herein. A presently preferred adhesive is an acrylate copolymer pressure sensitive adhesive formed from a 90/10 weight percent monomer ratio of 2-methylbutyl acrylate/acrylic acid in a 65/35 heptane/acetone solvent system (39-41% solids) and having an inherent viscosity of about 0.7-0.85 dl/g.
