Abstract
(ⅱ) 상기 기재 필름의 식각 처리된 표면에 코팅되어 있으면 실리콘계 화합물 및 실란계 화합물 중에서 선택된 1종을 포함하는 프라이머층(B); 및
(ⅲ) 상기 프라이머층(B) 표면에 코팅되어 있으며, 실리콘 고무, 방열필러 및 내열향상제를 포함하는 조성물을 경화시켜 제조되며, 상기 방열필러의 함량이 방열 실리콘 고무층 전체중량 대비 10~90중량%이고, 열전도도가 0.4~4.0 W/mk이고, 길이방향 표면조도 및 폭방향 표면조도가 0.01~4.0㎛인 방열 실리콘 고무층(C); 으로 구성된다.
본 발명은 연속 압착에 대한 복원력과 열전도 효율도 우수하여 연속적으로 열 압착이 가능하고, 표면조도 및 평활성도 우수하여 도전필름(ACF)에 대한 이형성과 도전볼 형성, 드라이브I·C의 오염방지에도 큰 장점이 있다. 이러한 장점 때문에 폭이 50 인치 이상의 광폭 액정디스플레이(LCD) 제조에도 충분히 적용이 가능하다.
