역 반사성 시이팅 용의 투명한 다층 커버필름
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 렌즈가 내장된 역반사성 시이팅을 제공하기 위하여 역반사 기층물질에 대해 투명한 다층 커버필름을 적용한 것을 나타내는 횡단면도이다.
제2도는 또 다른 렌즈가 내장된 역반사성 시이팅을 제공하기 위하여 다른 형태의 역반사 기층물질에 대하여 투명한 다층 커버필름을 적용한 것을 나타내는 횡단면도이다.
제3도는 투명한 다층 커버필름을 갖는 렌즈가 캡슐화된 역반사성 시이팅을 나타내는 횡단면도이다.

Claims (15)

  1. 커버필름이 다층 필름이며, 외층은 메틸메타크릴레이트와 또 다른 아크릴레이트 또는 메타크릴레이트를 비롯한 모노머의 아크릴 공중합체를 포함하며, 그것의 알킬 또는 아르알킬기는 8개까지의 탄소원자를 포함하며, 메틸메타크릴레이트는 20 내지 90중량 퍼센트의 모노머를 포함하며 내층은 열가소성 지방족 우레탄 중합체를 포함하는 것을 특징으로 하는, 평면의 투명커버필름을 가지는 역반사성 시이팅.
