Abstract

표면에 3차원의 패턴을 갖는 연속 이형시트의 3차원의 패턴이 있는 면에 열가소성 수지를 압출하여 따라서 상기 열가소성 수지의 표면에 상기 패턴을 전사하고 동시에 불균일한 패턴 또는 거울 표면을 갖는 냉각롤로 상기 열가소성 수지의 다른 면을 접촉시켜 따라서 상기 냉각롤과 접촉하여 있는 상기 열가소성 수지의 표면으로 상기 패턴 또는 거울표면을 전사하는 단계, 그리고 냉각후 상기 열가소성 수지로부터 상기 이형 시트를 박리하여 분리하는 단계로 얻어지는, 광학 기능이 부여된 연속시트를 개시한다. 연속시트는 선 자국이나 흠집이 없고 원하는 크기와 형태로 자유로이 자를 수 있다.
