  • Double-sided pressure-sensitive adhesive tape, laminated structure comprising the same, and method of use of same
    Patent number: 5372865
    Abstract: In the double-side pressure-sensitive tapes (A and B) of the first embodiment of the present invention, a first pressure-sensitive adhesive layer (2) comprising a blend of 100 parts by weight of an acrylic or rubber-based pressure-sensitive adhesive composition with from 0.01 to 30 parts by weight of a silicone polymer is formed on one side of a substrate and an acrylic or rubber-based pressure-sensitive adhesive layer is formed as a second pressure-sensitive adhesive layer (3) on the other side. By this, a double-side pressure-sensitive tape in which the pressure-sensitive adhesives, even when being bonded to each other, can thereafter be easily separated is obtained.

  • Pressure-sensitive tape, pressure-sensitive tape-fixing structure, and roll of pressure-sensitive tape
    Patent number: 5264264
    Abstract: A pressure-sensitive tape, a pressure-sensitive tape-fixing structure comprising a member made of a material having a rough surface, having fixed thereto the pressure-sensitive tape, and a roll of the pressure-sensitive tape are disclosed, the pressure-sensitive tape comprising a pressure-sensitive tape comprising a tape substrate, a first pressure-sensitive adhesive area provided on one side of the tape substrate in a tape substrate part which is close to one end of the tape substrate, and a second pressure-sensitive adhesive area provided on one side of the tape substrate in a tape substrate part which is close to the other end of the tape substrate, wherein either or both of said first pressure-sensitive adhesive area and said second pressure-sensitive adhesive area have a strongly adhesive area at an end part thereof to which an external peeling force is to be applied first, and said strongly adhesive area has a peel strength higher than that of the other part of the pressure-sensitive adhesive area.
