    • A multilayer adhesive tape having a backing based on an oriented thermoplastic film, whose upper face is coated, if desired, with a release coating and to whose lower face the following layers have been applied: a) a primer layer which is not applied over the full area and which anchors very well to the thermoplastic film, b) a first release layer which is applied over the full area of the applied primer layer, and the free thermoplastic film surface, the first release layer anchoring better to the primer layer than to the thermoplastic film, c) a second release layer which is applied over the full area of the first release layer and which is anchored better on the first release layer than the first release layer on the film surface and which has worse adhesion to the first release layer than adhesive composition to the adhesion substrate, d) a pressure-sensitive adhesive composition which is applied over the full area of the second release layer and which is anchored better on the second release layer than the second release layer on the first release layer.
    • 一种多层粘合带,其具有基于定向热塑性膜的背衬,如果需要,其上表面用剥离涂层涂覆,并且其下表面已经施加以下层:a)未涂覆在底层上的底漆层 全部区域,并且其非常好地锚定到热塑性膜上,b)施加在所施加的底漆层的整个区域上的第一释放层和游离热塑性膜表面,第一释放层更好地锚定到底漆层,而不是 所述热塑性膜,c)第二剥离层,其施加在所述第一剥离层的整个区域上并且比所述膜表面上的第一剥离层更好地锚固在所述第一剥离层上,并且对所述第一剥离部的粘附性较差 层,而不是粘合剂组合物; d)压敏粘合剂组合物,其施加在第二释放层的整个区域上并且在第二释放层上更好地锚定 释放层比第一释放层上的第二释放层。
