An adhesive composition according to embodiments of the present invention comprises an acryl-based copolymer, an organometallic compound, and an isocyanate compound, wherein the acryl-based copolymer comprises a polymer of a monomer blend comprising 80 to 97 wt% of an alkyl(meth)acrylate monomer having an alkyl group having a carbon number of 8 or greater, and 3 to 20 wt% of a polar monomer, and 3 wt% or less of an acid group-containing polar monomer. This adhesive sheet comprising an adhesive layer can provide excellent recovery rate, adhesive force, and folding properties. Une composition adhésive selon des modes de réalisation de la présente invention comprend un copolymère à base acrylique, un composé organométallique et un composé isocyanate, le copolymère à base acrylique comprenant un polymère d'un mélange de monomères comprenant de 80 à 97% en poids d'un monomère de (méth)acrylate d'alkyle ayant un groupe alkyle ayant un nombre de carbones de 8 ou plus, et de 3 à 20% en poids d'un monomère polaire, et 3% en poids ou moins d'un monomère polaire contenant un groupe acide. Cette feuille adhésive comprenant une couche adhésive peut fournir un excellent taux de récupération, une excellente force adhésive et des propriétés de pliage. 본 발명의 실시예들에 따른 점착제 조성물은 아크릴계 공중합체, 유기 금속 화합물 및 이소시아네이트 화합물을 포함하며, 아크릴계 공중합체는 탄소수 8 이상의 알킬기를 갖는 알킬(메타)아크릴레이트 단량체 80 내지 97중량%, 극성 단량체 3 내지 20중량% 및 3중량% 이하의 산기 함유 극성 단량체를 포함하는 단량체 블렌드의 중합체를 포함한다. 점착제층을 포함하는 점착 시트는 우수한 복원율, 밀착력 및 폴딩 특성을 제공할 수 있다.
