Abstract

본 발명의 점착제 조성물은 (메타)아크릴계 공중합체; 하기 화학식 1로 표시되는 올리고머형 실록산; 및 가교제를 포함하며, 상기 (메타)아크릴계 공중합체는 지환족, 방향족 또는 이들의 조합을 함유하는 것을 특징으로 한다: [화학식 1] (상기에서, R1, R2 및 R3는 각각 독립적으로 탄소수 1~5의 알킬기이고, R4 및 R5는 각각 독립적으로 탄소수 1~6의 알킬기 또는 탄소수 6~12의 아릴기이며, n은 3~25의 정수이고, m은 1~10의 정수임)
PURPOSE: An adhesive composition is provided to have excellent durability, tailor ability, and workability and to effectively suppress the resistance alteration of an electrode layer under the severe condition while minimizing indium tin oxide (ITO) corrosion. CONSTITUTION: An adhesive composition comprises a meth-acrylic group copolymer; oligomeric siloxane; and a cross-linking agent. The meth-acrylic group copolymer contains a cycloaliphatic group and an aromatic group or the combination thereof. The R1, the R2 and the R3 are respectively C1-5 alkyl groups in a chemical formula 1. The R4 and the R5 are respectively C1-6 alkyl groups or the C6-12 aryl groups. The N is the fixed number of 3-25. The m is the fixed number of 1-10. The glass transition temperature of the meth-acrylic group copolymer is (-50)-0°C.
