Abstract: A pressure-sensitive adhesive sheet including a pressure-sensitive adhesive layer having an adhesive strength reducible by an adhesive strength-reducing action. For example, the pressure-sensitive adhesive layer is a thermally releasable pressure-sensitive adhesive layer (11), and the adhesive strength-reducing action is heating of the pressure-sensitive adhesive layer (11). This pressure-sensitive adhesive sheet for build stage use is suitable for allowing an object to be formed over a build stage of an additive manufacturing apparatus to be attached to the build stage during building up, and to be readily detached from the build stage after building up. An additive manufacturing apparatus can employ the pressure-sensitive adhesive sheet for build stage use and includes a build stage, and adhesive strength-reducing means for performing an adhesive strength-reducing action to a pressure-sensitive adhesive layer of the pressure-sensitive adhesive sheet for build stage use affixed to the stage.

Abstract: A pressure-sensitive adhesive sheet (X1), which is a pressure-sensitive adhesive sheet for build stage use according to the present invention, has a multilayer structure typically including a substrate (11) and a pressure-sensitive adhesive layer (12). The pressure-sensitive adhesive sheet (X1) has a puncture strength of 3.3 to 12 N, where the puncture strength is determined as a maximum load during a process in which a probe having a hemispherical head with the radius of curvature of 0.5 mm pierces the pressure-sensitive adhesive sheet at a travel speed of 0.2 mm/s. The pressure-sensitive adhesive sheet for build stage use is suitable for detachment of an object, which is formed on a build stage typically of an additive manufacturing apparatus, from the build stage while less causing the significant damage to the object.

Abstract: There is provided an electrically peelable adhesive composition that is for forming an adhesive layer which has high adhesion and can be easily peeled off by applying a voltage for a short time even at a low voltage. In addition, there is provided an adhesive sheet including an adhesive layer formed of the composition that has high adhesion and can be easily peeled off by applying a voltage for a short time even at a low voltage, and a joined body of the adhesive sheet and an adherend. The electrically peelable adhesive composition of the invention includes a polymer and an ionic liquid, in which an anion of the ionic liquid is a bis(fluorosulfonyl)imide anion. A content of the ionic liquid is preferably 0.5 to 30 parts by weight with respect to 100 parts by weight of the polymer.
