Abstract
본 발명은 광-편광 특성을 나타내는 이외에, 청색방출(blue leakage)이 존재하지 않음을 특징으로 하는, 폴리아세틸렌과 요오드를 광-편광 물질로서 함유하는 편광필름에 관한 것이다.
Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
Claims (4)
- 폴리아세틸렌과 요오드를 광-편광 물질로서 함유함을 특징으로 하는, 폴리비닐 알콜계 편광 필름
- 아세틸렌을 폴리비닐 알콜 용액 속에서 중합시키고, 폴리아세틸렌을 함유하는 폴리비닐 알콜 용액을 필름으로 가공하며, 필름을 이의 최초 길이의 4내지 13배로 연산시킨 다음 요오드를 가공된 필름내로 확산시킴을 특징으로 하여, 광-편광 물질로서 폴리아세틸렌과 요오드를 모두 함유하는 폴리비닐 알콜계 편광 필름을 제조하는 방법.
- 제2항에 있어서, 연산시키는 동안 필름을 bo/lo의 비(여기서, bo는 최초 폭이고 lo는 압체되는 경우에 필름의 최초 길이이다)가 확실이 3이하가 되도록 압체시킴을 특징으로 하는 방법.
- 제1항에 있어서, 폴리아세틸렌을 니켈 촉매 중합반응을 사용하여 폴리비닐 알콜 속에서 제조합을 특징으로 하는, 편광필름※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
