Abstract:
(EN) This adhesive sheet is formed from an adhesive composition which contains: 100 parts by weight of (A) an acrylic resin that is a copolymer obtained from a monomer mixture which contains 95-99.9% by weight of a (meth)acrylic acid ester and 0.1-5% by weight of an unsaturated monomer having a polar functional group; 0.01-5 parts by weight of (B) a crosslinking agent; 0.2-8 parts by weight of (C) an ionic compound having an organic cation and a melting point of from 25°C to 50°C (inclusive); (D) a silane compound having a boiling point of 350°C or less; and (E) an organic solvent. This adhesive sheet is configured such that the weight ratio of silicon atoms derived from the silane compound (D) relative to the adhesive sheet is 160 mg/kg or more.
(FR) La feuille adhésive ci-décrite est formée à partir d'une composition adhésive qui contient : 100 parties en poids de (A) une résine acrylique qui est un copolymère obtenu à partir d'un mélange de monomères qui contient 95-99,9 % en poids d'un ester d'acide (méth)acrylique et 0,1-5 % en poids d'un monomère insaturé ayant un groupe fonctionnel polaire ; 0,01-5 parties en poids de (B) un agent de réticulation ; 0,2-8 parties en poids de (C) un composé ionique ayant un cation organique et un point de fusion de 25 à 50°C (inclus) ; (D) un composé de silane ayant un point d'ébullition de 350°C ou moins ; et (E) un solvant organique. Cette feuille adhésive est conçue pour que le rapport en poids des atomes de silicium dérivés du composé de silane (D) par rapport à la feuille adhésive soit de 160 mg/kg ou plus.
