Abstract:
(EN) The purpose of the present invention is to provide: an adhesive composition for flexible image display devices which includes a (meth)acrylic polymer formed from specific monomers; an adhesive layer for flexible image display devices which is formed from the adhesive composition; a laminate for flexible image display devices which, as a result of using the adhesive layer and an optical laminate, exhibits excellent bending resistance and adhesive properties, and does not peel even after repeated bending; and a flexible image display device in which the laminate for flexible image display devices is provided. The adhesive composition for flexible image display devices includes a (meth)acrylic polymer including, as monomer units: at least one monomer having a reactive functional group selected from the group consisting of hydroxyl group-containing monomers, carboxyl group-containing monomers, amino group-containing monomers, and amide group-containing monomers; and a (meth)acrylic monomer having a straight-chain or branched-chain C1-24 alkyl group. The adhesive composition for flexible image display devices is characterized in that the at least one monomer having the reactive functional group accounts for 0.02-10 wt% of all monomers forming the (meth)acrylic polymer.
(FR) Le but de la présente invention est de fournir une composition adhésive pour des dispositifs d'affichage d'image souples qui comprend un polymère (méth)acrylique formé à partir de monomères spécifiques ; une couche adhésive pour des dispositifs d'affichage d'image souples qui est formée à partir de la composition adhésive ; un stratifié pour des dispositifs d'affichage d'image souples qui, du fait de l'utilisation de la couche adhésive et d'un stratifié optique, présente d'excellentes propriétés d'adhésion et de résistance au pliage, et ne se décolle pas même après des pliages répétés ; et un dispositif d'affichage d'image souple comportant le stratifié pour dispositifs d'affichage d'image souples. La composition adhésive pour dispositifs d'affichage d'image souples comprend un polymère (méth)acrylique comprenant, en tant qu'unités monomères : au moins un monomère comportant un groupe fonctionnel réactif choisi dans le groupe constitué par les monomères contenant des groupes hydroxyle, des monomères contenant des groupes carboxyle, des monomères contenant des groupes amino et des monomères contenant des groupes amide ; et un monomère (méth)acrylique comportant un groupe alkyle en C1 à C24 à chaîne linéaire ou ramifiée. La composition adhésive pour dispositifs d'affichage d'image souples est caractérisée en ce que ledit monomère comportant le groupe fonctionnel réactif représente de 0,02 à 10 % en poids de tous les monomères formant le polymère (méth)acrylique.
