1. A double-sided adhesive tape which can be released from a substrate to which it is adhered without leaving a residue on said substrate and without destruction of said substrate, said double-sided adhesive tape comprising:
- a) an intermediate support having a length and a width defining two opposite sides, which intermediate support cleaves along the entirety of its length and along the entirety of its width into two pieces when subjected to a torsional force, lever force and/or peel force; and
b) pressure-sensitive adhesive composition coated on both sides of the intermediate support.

Abstract
Double-sided adhesive tape (fixer) which can be re-released without residue or destruction for hidden bonding on substrates that are to be bonded, with high peel strength, high shear strength and high tip-shear strength, characterized by
- a) an intermediate support which cleaves under the action of torsional forces, lever forces and/or peel forces,
- b) pressure-sensitive adhesive composition coated on both sides of the intermediate support, which composition can be released without residue or destruction by stretching in the direction of the bond plane.

17. A double-sided adhesive tape which can be released from a substrate to which it is adhered without leaving exposed adhesive on the substrate, said tape comprising:
-
a) an intermediate support having a top surface and a bottom surface; and
b) pressure-sensitive adhesive coatings on the top and bottom surfaces;
wherein the intermediate support is cleavable into two pieces along a surface that extends entirely between the top and bottom surfaces when the intermediate support is subjected to a torsional force, a lever force and/or a peel force, with each of the two pieces adjacent to only one of the adhesive coatings.
