Document Type and Number:
WIPO Patent Application WO/2018/181769
Kind Code:
A1
Abstract:
Provided is an adhesive sheet comprising a layered body in which an adhesive layer (X1) and a non-adhesive thermally expandable substrate (Y) are directly layered in this order. The layered body is formed by directly layering, in this order, a material for forming the adhesive layer (X1), namely, a coating film (x1') comprising a composition (x1), and a material for forming the thermally expandable substrate (Y), namely, a coating film (y') comprising a composition containing a resin and thermally expandable particles, then simultaneously irradiating the coating film (x1') and the coating film (y') with an energy beam. The adhesive sheet leaves little adhesive residue on the surface of an adherend after being heated and peeled off, has good interfacial adhesion between the substrate and the adhesive layer, and exhibits excellent adhesion during temporary fixing and excellent peelability when heated.
