<p>PROBLEM TO BE SOLVED: To obtain a thermally releasable type tacky sheet capable of forming and ensuring a sufficient interval between cut pieces formed by cutting processing of an adherend and withstanding heat treatment at the time of expanding a thermally expandable layer. SOLUTION: This thermally releasable type tacky sheet is obtained by forming a thermally expandable layer containing thermally expandable microspheres and a tacky layer containing a tacky substance on at least one surface of a substrate 1 having heat resistance and stretchability. The substrate 1 can be composed of a heat stabilizer-containing flexible vinyl chloride film, a stretchable polyester film, a flexible polyolefin film or a sheet, a rubber-based polymer sheet or a multilayered film or sheet, or the like, comprising the substrate materials. The thermally expandable layer and the tacky layer may integrally be formed. The thermally expandable layer 2 and the tacky layer may be formed on one surface of the substrate 1 and the tacky layer containing the tacky substance may be formed on the other surface of the substrate 1.</p> |
