Title
(KO) 박리제 조성물, 박리 시트, 편면 점착 시트 및 양면 점착 시트
Abstract
(KO)
본 발명의 박리제 조성물은 폴리에스테르 수지(A)와 아크릴 폴리머(B)를 포함하고, 상기 아크릴 폴리머(B)가, 하기 구조식(1)을 구성 단위로 가지고 있으며, 상기 폴리에스테르 수지(A)의 배합량과 상기 아크릴 폴리머(B)의 배합량의 비율은 질량비로 (A):(B)=50:50~95:5의 범위인 것을 특징으로 한다. 본 발명에 따르면, 이러한 박리제 조성물로 형성되는 박리 시트, 편면 점착 시트 및 양면 점착 시트를 제공할 수 있다. 또한, 박리제 조성물로 형성되는 박리 시트를 롤형상으로 권취했을 때 박리 시트의 기재 표면으로 박리제 조성물이 이행되는 것을 억제함과 아울러, 박리 시트에 경박리성을 부여할 수 있다. (식 중, R은 H 또는 CH, R는 분기 구조를 가진 탄소수 10 이상 30 이하의 알킬기이다.) JPEG 112017089866302-pct00006.jpg 34 105 1 3 2
