DOUBLE-FACED ADHESIVE TAPE, LAMINATE STRUCTURE THEREOF, ADHESIVE TAPE, AND METHOD OF USING SAID TAPES

摘要

Adhesive tapes, one of which is a first double-faced adhesive tape (A, B) one surface of the base material of which is coated with a first adhesive layer (2) constituted of 100 parts by weight of acrylic or rubber adhesive composition mixed with 0.01 to 30 parts by weight of silicone polymer and the other surface with a second adhesive layer (3) constituted of acrylic or rubber adhesive layer. Thus, a double-faced adhesive tape capable of being easily released and separated from each other after stuck to each other can be obtained. A second adhesive tape is composed of a second adhesive layer (54) on one (53a) of the lapped both inner surfaces of a base material (53) as well as of a first adhesive layer (55) on the other inner surface (53b) in such manner that the both layers are respectively constituted of compositionally different adhesives so as to be released from each other and, further, composed of a third adhesive layer (56) on a proper part other than said lapping surfaces of the base matieral (53) thereof. In this way, the strength of the tape for fixed adhesion can be increased without enlarging the area of the base material.
