ABSTRACT:
An adhesive material which protects against being reused, which comprises a released sheet (12), an adhesive layer (14) laminated on one main surface of said release sheet (12), a second layer (16) which can be cut or torn by fingers and laminated on said adhesive layer (14), an adhesion layer (18) laminated on said second layer (16), and a first layer (20) laminated and adhered temporarily on said adhesion layer (18). According to the present invention, the first and second layers are adhered temporarily by the adhesion layer in such a state that re-adhering is hardly possible. Thus when attempting to tear off the adhering material, the first layer is separated from the second layer and re-adhering is impossible.
