Tackified crosslinked acrylic adhesives

Normally tacky and pressure-sensitive adhesive tape comprising a sheet material having, on at least one surface, a thin layer of normally tacky and pressure-sensitive adhesive containing trace amounts of solvent and consisting essentially of an at least substantially surfactant-free blend of (a) a crosslinked pressure-sensitive copolymer of 100 parts by weight of monomers consisting essentially of iso-octyl acrylate and 3-7 parts by weight of acrylic acid, said copolymer, prior to crosslinking being soft, tacky, and having an inherent viscosity on the order of 0.75-1.5 dl/g, (b) a small amount of an antioxidant that is based on either a hindered phenol or a sulfur-containing organo-metal salt, and (c) a tackifying rosin ester, said adhesive having the properties of (1) a rolling ball tack value of less than 6 cm, (2) an ability to bond firmly to stainless steel, ABS terpolymer, low density polyethylene, and isotactic polypropylene, and (3) a shear value of at least 5,000 minutes at 70.degree.
