Abstract: A double-sided adhesive sheet has a laminate structure including a first adhesive layer containing an electrolyte, a second adhesive layer, and a conduction substrate. A double-sided adhesive sheet joined body includes, for example, an adhesive sheet having such a laminate structure, a first conductive adherend to which the first adhesive layer adheres, and a second adherend to which the second adhesive layer adheres. A method for joining/separating adherends includes joining first and second adherends to each other via the adhesive sheet, then applying a voltage to the first adhesive layer so as to generate a potential difference in a thickness direction of the first adhesive layer, and separating the first and second adherends from each other.

Abstract: Provided is a PSA sheet having a PSA layer. The PSA layer includes a layer A forming at least one surface thereof. The PSA sheet has an adhesive strength N0 of 2.0 N/10 mm or greater, after one day at room temperature following application of the layer A side to a surface of an alkaline float glass plate as an adherend having a contact angle of 5°-10° with distilled water; has an N1 to N0 reduction rate of 30% or lower, wherein N1 is a water-resistant adhesive strength measured after stored at room temperature for one day, immersed in water for 30 minutes, taken out from the water and then residual water is wiped off, and has an N2 to N0 reduction rate of 40% or higher, wherein N2 is a water-peel strength measured after stored at room temperature for one day, 20 μL distilled water is dropped onto the adherend and is allowed to enter a PSA layer/adherend interfacial edge. N2 is measured at a tensile speed of 300 mm/min at a peel angle of 180°.

Abstract: Provided is a method for peeling a PSA sheet adhered on a polarizing plate. The PSA sheet has a PSA layer. The PSA layer includes a layer A forming at least one surface of the PSA layer. Of the polarizing plate, the surface to which the PSA sheet is adhered is corona-treated or plasma-treated. The peeling method includes a water-peel step in which the PSA sheet is peeled from the polarizing plate, in a state where an aqueous liquid exits at the interface between the polarizing plate and the PSA sheet at the front line of peeling the PSA sheet from the polarizing plate, with the aqueous liquid allowed to further enter the interface following the movement of the peel front line.
