Abstract
The present invention provides an acrylate/silicone pressure-sensitive adhesive tape having improved adhesion to painted surfaces and low temperature performance. The pressure-sensitive adhesive tape comprises: PA1 (a) a pressure-sensitive adhesive layer comprising a polymerized pressure sensitive adhesive composition wherein said pressure sensitive adhesive composition comprises: PA2 (I) about 25 to about 99 weight percent of polymer of the formula ##STR1## wherein: X, Y, D, R, R.sup.1, R.sup.2, R.sup.3, R.sup.4, and n are defined in the specification; PA2 (II) about 1 to about 75 weight percent free radically polymerizable vinyl monomer which is capable of copolymerizing with the polymer wherein said free radically polymerizable monomer comprises: PA3 (i) about 5 to about 100 parts by weight of an acidic monomer selected from the group consisting of methacrylic acid, acrylic acid, and mixtures thereof; PA3 (ii) about 0 to about 95 parts by weight of an acrylate monomer selected from the group consisting of esters of acrylic acid comprising 4 to 21 carbon atoms and esters of methacrylic acid comprising 5 to 21 carbon atoms and mixtures thereof; based upon 100 parts total by weight…
