双面粘合带和研磨构件
摘要：
本发明提供一种双面粘合带和研磨构件。一种双面粘合带，具有：基材，丙烯酸类粘合剂层，橡胶类粘合剂层，设置在橡胶类粘合剂层的外侧的第一剥离衬垫，和设置在丙烯酸类粘合剂层的外侧的第二剥离衬垫。第一剥离衬垫分别具有聚合物层和纸基材层。另外，第二剥离衬垫分别具有聚合物层和纸基材层。根据JIS K评价的各聚合物层表面的动摩擦系数小于1.0。
摘要（英）：

The invention provides a double-faced adhesive tape and a polishing member. The double-faced adhesive tape has a substrate, an acrylic pressure-sensitive adhesive layer, a rubber pressure-sensitive adhesive layer, and a first release liner that is formed on an external side of the rubber pressure-sensitive adhesive layer, and a second release liner that is formed on an external side of the acrylic pressure-sensitive adhesive layer. The first release liner each has a polymer layer and a paper substrate layer. Further, the second release liner each has a polymer layer and a paper substrate layer. Dynamic friction coefficient on the surface of each polymer layer is less than 1.0, when the coefficient is measured according to JIS K.
