ABSTRACT:
By incorporating hydrophobic silica into acrylic pressure-sensitive adhesive tape, the shear strength at elevated temperatures is significantly improved, and adhesion and physical properties are maintained or improved. The hydrophobic silica preferably has a surface area from 50 to 400 m.sup.2 /g. A preferred acrylic pressure-sensitive adhesive layer comprises a copolymer of (a) at least one alkyl acrylate having an average of 4-12 carbon atoms in its alkyl group and (b) from 3 to 20% by weight of copolymerizable monomer having a polar group such as acrylic acid.
