Abstract: The present invention relates to a method for manufacturing a laminate, including: a laminating step of laminating a side of a thermal transfer layer of a thermal transfer sheet having a release sheet and the thermal transfer layer on at least a part of a surface of a resin member by heat bonding, in which the release sheet has no yield points, and has an elongation at break of 100% to 600% in a stress-strain curve measured by a tensile test at a molding temperature Tβ° C. in the laminating step.

Abstract: An adhesion method including: a step (1), disposing a stickable-curable adhesive layer on a first adherend; a step (2), disposing a curing agent layer on a second adherend, the curing agent layer being able to cure the stickable-curable adhesive layer by contacting and reacting with the stickable-curable adhesive layer; and a step (3), bringing the stickable-curable adhesive layer into contact with the curing agent layer so that they are sandwiched by the first adherend and the second adherend.

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.
