PRESSURE-SENSITIVE ADHESIVE SHEET EXFOLIATIVE WITH HEAT

摘要

A pressure-sensitive adhesive sheet exfoliative with heat having, on at least one side of a substrate, a thermally expandable layer containing thermally expandable microspheres and an adhesive layer containing an adhesive material, wherein the substrate has good thermal resistance and elasticity. The inventive adhesive sheet is advantageous in that, when a body having a sheet adhered thereon is cut, the use of the inventive sheet results in a high operability and workability in an exfoliation and recovery step, since pieces formed by cutting can hold a satisfactory distance from one another and are resistant to a heat treatment applied for expanding the thermally expandable layer.
