    • PROBLEM TO BE SOLVED: To provide a release sheet in which a linear protruded part is formed on the surface, the release sheet being attached to an attaching surface without involving foam and attached to the attaching surface after readily eliminating foam even when foam is involved, when releasing the release sheet and then attaching an adhesive to an adherend.
      SOLUTION: The release sheet is used for forming a recessed part on the surface of the adhesive layer of the adhesive sheet. The release sheet includes: a release sheet substrate; a first continuous linear protruded part formed on the sheet substrate; and a second continuous linear protruded part, wherein the first continuous linear protruded part is mutually crossed with the second continuous linear protruded part. As a result, many lattices each composed of four sides having acute angle parts are formed on the longitudinal direction side of the release sheet.

    • PROBLEM TO BE SOLVED: To provide a cloth adhesive tape having a foamed adhesive layer having many closed cells homogeneously dispersed in the hot-melt type adhesive layer and formed by the volatilization of a volatile material, and to provide a method for producing the cloth adhesive tape. SOLUTION: The cloth adhesive tape is produced by forming the hot-melt type adhesive layer on the woven fabric face side of a base material having a layered structure obtained by arranging a synthetic resin layer as a lining material on one surface of the woven fabric. The synthetic resin layer of the lining material, or a second synthetic resin layer formed on the woven fabric face is a synthetic resin layer formed out of a synthetic resin composition containing 30-300 pts.wt. of a porous filler based on 100 pts.wt. of a synthetic resin. The hot-melt type adhesive layer is the foamed adhesive layer containing the many closed cells formed by the volatilization of the volatile material. The method for producing the adhesive tape is also provided. COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:提供一种具有发泡粘合剂层的布胶带,该发泡粘合剂层具有均匀分散在热熔型粘合剂层中并且通过挥发性物质的挥发而形成的许多闭孔,并提供一种生产方法 布胶带。 解决方案:通过在具有层叠结构的基材的织物表面侧上形成热熔型粘合剂层而制成布胶带,所述层叠结构通过在合成树脂层的一个表面上布置合成树脂层作为衬里材料 无纺布。 衬里材料的合成树脂层或在织物表面上形成的第二合成树脂层是由含有30-300重量份的合成树脂组合物形成的合成树脂层。 基于100重量份的多孔填料 的合成树脂。 热熔型粘合剂层是包含通过挥发性物质的挥发而形成的许多闭孔的发泡粘合剂层。 还提供了生产胶带的方法。 版权所有(C)2011,JPO&INPIT
