Abstract
This invention provides an adhesive tape which can easily be cut in the lateral direction by hand, and a process for preparation thereof. The adhesive tape comprises (1) a fabric base in which the warp and filling are made of thermoplastic yarns, the denier of the warp yarns is lower than that of the filling yarns and the number of warp yarns per inch is larger than the number of filling yarns per inch; (2) a first thermoplastic layer which is laminated on the surface of said fabric base; (3) a second thermoplastic layer which is laminated on at least one of the surfaces (1) and (2); and a pressure-sensitive adhesive which is applied to at least one of the surfaces of (1), (2) and (3).
