<P>PROBLEM TO BE SOLVED: To provide an easily-releasable pressure-sensitive adhesive sheet and an easily-releasable pressure-sensitive adhesive tape which are easily released even when they have been subjected to a process under a high temperature atmosphere. <P>SOLUTION: The easily-releasable pressure-sensitive adhesive sheet is formed by mixing a side-chain crystalline polymer with at least one selected from a straight silicone oil, and a non-reactive silicone oil, and the adhesive strength thereof is reduced at a temperature lower than the melting point of the side-chain crystalline polymer. The easily-releasable pressure-sensitive adhesive tape is formed by arranging an adhesive layer on at least one surface of a substrate film, the adhesive layer is formed by mixing a side-chain crystalline polymer with at least one selected from a straight silicone oil and a non-reactive silicone oil, and the adhesive strength thereof is reduced at a temperature lower than the melting point of the side-chain crystalline polymer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
