PROBLEM TO BE SOLVED: To provide a film having excellent adhesiveness to a curved surface and to provide an adhesive tape formed of the film. SOLUTION: The film comprises at least one PVC polymer and at least one plasticizer, and further comprises 2-25 pts.wt. of an additive polymer in the form of a crosslinked or PVC-incompatible polymer per 100 pts.wt. of the PVC polymer and 25-37 pts.wt. of a polymer plasticizer per 100 pts.wt. of the PVC polymer, excluding the additive polymer. Consequently, the film has high stretchability and good hand tearability and allows production of advantageous adhesive tapes, especially adhesive masking tapes. COPYRIGHT: (C)2010,JPO&INPIT |
