Title (EN) ADHESIVE SHEET
(FR) FEUILLE ADHÉSIVE
(JA) 粘着シート
Abstract:
(EN) 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) containing an adhesive resin, and a material for forming the thermally expandable substrate (Y), namely, a coating film (y') comprising a composition (y) containing a resin and thermally expandable particles, then simultaneously drying the coating film (x1') and the coating film (y'). 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.
(FR) La présente invention concerne une feuille adhésive comprenant un corps stratifié dans lequel une couche adhésive (X1) et un substrat non adhésif thermiquement expansible (Y) sont directement stratifiés dans cet ordre. Le corps stratifié est formé en stratifiant directement, dans cet ordre, un matériau pour former la couche adhésive (X1), à savoir, un film de revêtement (x1’) comprenant une composition (x1) contenant une résine adhésive, et un matériau de formation du substrat thermiquement expansible (Y), à savoir, un film de revêtement (y’) comprenant une composition (y) contenant une résine et des particules thermiquement expansibles, puis en séchant simultanément le film de revêtement (x1’) et le film de revêtement (y’). La feuille adhésive laisse peu de résidu adhésif sur la surface d’une partie adhérée après avoir été chauffée et décollée, présente une bonne adhérence interfaciale entre le substrat et la couche adhésive, et fait preuve d’une excellente adhérence durant la fixation temporaire et d'une excellente pelabilité lorsqu’elle est chauffée.
(JA) 粘着剤層(X1)及び非粘着性である熱膨張性基材(Y)がこの順で直接積層されている積層体を有する粘着シートであって、 前記積層体が、 粘着剤層(X1)の形成材料である、粘着性樹脂を含む組成物(x1)からなる塗膜(x1')と、 熱膨張性基材(Y)の形成材料である、樹脂及び熱膨張性粒子を含む組成物(y)からなる塗膜(y')と、 をこの順で直接積層した後、塗膜(x1')及び塗膜(y')を同時に乾燥して形成されたものである、粘着シートを提供する。 当該粘着シートは、加熱剥離後の被着体表面の糊残りが少なく、基材と粘着剤層の間の界面密着性が良好であり、仮固定時の接着性及び加熱剥離性に優れる。
