Document Type and Number:
WIPO Patent Application WO/2019/131555
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a stacked body including an adherend, and an adhesive piece which partially covers the adherend. The manufacturing method includes, in this order: an affixing step of affixing to the adherend an adhesive sheet including a base material layer and an adhesive layer stacked onto at least the adherend-side surface of the base material layer; a cutting step of performing a cutting process along a boundary of a first region of the adhesive sheet constituting the adhesive piece, and a second region not constituting the adhesive piece; a partial removal step of removing the second region from the adherend by peeling, while leaving the first region on the adherend; and an adhesive force raising step of raising the adhesive force of the first region with respect to the adherend. Here, the adhesive force raising step includes a heating process, and the adhesive layer contains a polymer A of which Tg is less than 0°C, and which includes N-vinyl cyclic amide as a constituent monomer component, and a polymer B which is a copolymer of a monomer having a polyorganosiloxane skeleton and a (meth)acrylic monomer.
