description Disclosed is a heat-expandable/peelable acrylic pressure-sensitive adhesive tape or sheet which includes at least a pressure-sensitive adhesive layer containing a blowing agent, a peelable or peel-assisting film layer comprising an oriented poly(ethylene terephthalate), and a viscoelastic substrate containing microparticles, in which at least the peelable or peel-assisting film layer and the microparticle-containing viscoelastic substrate constitute a multilayer structure, and the multilayer structure is arranged on or above at least one side of the pressure-sensitive adhesive layer so that the blowing agent-containing pressure-sensitive adhesive layer is in contact with the peelable or peel-assisting film layer with or without the interposition of another layer. La présente invention a pour objet une bande ou une feuille adhésive thermo-expansible / pelable en acrylique sensible à la pression qui comprend au moins une couche adhésive sensible à la pression contenant un agent gonflant, une couche de film pelable ou favorisant l'écaillage comprenant un poly (éthylène téréphtalate) orienté, et un substrat viscoélastique contenant des microparticules, dans laquelle au moins la couche de film pelable ou favorisant l'écaillage et le substrat viscoélastique contenant des microparticules constituent une structure multicouche, et la structure multicouche est disposée sur ou au-dessus d'au moins un côté de la couche adhésive sensible à la pression de sorte que la couche adhésive sensible à la pression contenant l'agent gonflant soit en contact avec la couche de film pelable ou favorisant l'écaillage avec ou sans l'interposition d'une autre couche.
