Title
(KO) 단차 흡수성이 향상된 광학 투명 점착 테이프 및 이의 제조방법
Abstract
(KO)
본 발명은 광학 투명 점착 테이프에 관한 것으로, 아크릴레이트계 화합물 및 광개시제를 부분 중합한 예비중합체 시럽, 1차 경화용 광개시제 및 2차 경화용 광개시제를 포함하는 광학 투명 점착 조성물로부터 제조되고, 상기 광학 투명 점착 조성물이 1차 경화됨으로써 반경화 상태가 유지되고, 반경화 상태로 단차를 갖는 기판에 점착된 후, 2차 경화됨으로써 완전 경화되는 단차 흡수성을 갖는 광학 투명 점착 테이프이다. 본 발명의 광학 점착 테이프는 단차 흡수성 및 내구성이 우수한 효과가 있다.
