Abstract

L'invention concerne une feuille multicouche (1) comprenant une feuille de support souple (2) et une couche d'adhésif (3) sensible à pression permettant de fixer ladite feuille multicouche sur une surface lisse et rigide (5). Ledit adhésif sensible à la pression s'enlève intégralement de la surface (5) et est chois pour présenter, en couche de 300 µm d'épaisseur, une résistance au pelage à 90· comprise entre 20 et 85 N/pouce sur le verre après un temps de repos de 3 jours, à une température de 70 ·C. La feuille de support (2) comprend de préférence au moins une couche endommageable (4) et présente une rupture intracouche lorsqu'on détache la feuille multicouche de la surface (5). L'invention porte aussi sur un adhésif sensible à la pression que l'on produit en polymérisant un précurseur comprenant a) un composant monomère qui contient un ou plusieurs acrylates d'alkyle dont les groupes alkyle comprennent en moyenne 4 à 14 atomes de carbone et 2 à 8 phr d'au moins un monomère copolymérisable ayant un groupe polaire; b) 5 à 15 phr de silice hydrophobe; c) un ou plusieurs initiateurs de polymérisation, et d) un ou plusieurs composés de réticulation en concentration donnant une densité de réticulation que l'on obtient en utilisant de l'hexanedioldiacrylate comme composé de réticulation de référence en concentration comprise entre 0,06 et 0,14 phr. L'invention se rapporte également à un adhésif sensible à la pression que l'on obtient en polymérisant un précurseurs comprenant: a) un composant monomère contenant un ou plusieurs acrylates d'alkyle dont les groupes alkyle ont en moyenne 4 à 14 atomes de carbone, et 8 à 20 phr d'au moins un monomère copolymérisable ayant un groupe polaire; b) 5 à 15 phr de silice hydrophobe; c) un ou plusieurs initiateurs de polymérisation et d) un ou plusieurs composés de réticulation en concentration donnant une densité de réticulation que l'on obtient en utilisant de l'hexanedioldiacrylate comme composé de réticulation de référence en concentration comprise entre 0,06 et 0,11 phr.
