Abstract

본 발명은 착색된 피복 조성물 및 착색되지 않은 피복 조성물을 캐리어 필름상에 동시에 압출시키는, 미리 계량첨가되는 압출 피복 공정을 사용하여 교차-웹 방향으로 다양한 두께 및 색의 구배를 갖는 복합 피복제를 제공한다. 이러한 복합 피복체는 착색 구배 띠를 갖는 자동차 바람막이와 같은 적층 구조물을 제조하는데 유용하다.

Description

상기 실시예는 다이의 공동을 적절하게 디자인함으로써 교차-웹 방향으로의 두께 변화를 얻을 수 있다는 것을 보여준다.

  7. 제1항에 있어서, 상기 층을 동시에 부착시키는 방법.
  8. 균일한 두께를 갖는 착색되지 않은 중합체성 접착체 수지층(28), 및 웹의 중앙 또는 가장자리로부터 측정하였을 때 교차-웹 방향으로 다양한 두께 및 색의 구배(a-b, c-d)를 갖는 착색된 중합체성 접착제 수지층(26)을 특징으로 하는 복합 피복층이 위에 있는 캐리어 필름(30).
  9. 제8항에 있어서, 상기 접착제 수지가 폴리비닐 부티랄인 캐리어 필름.
  10. 제8항에 있어서, 상기 착색제가 안료인 캐리어 필름.
  11. 제8항에 있어서, 상기 각각의 층의 최대 건조 피복 두께가 100μ인 캐리어 필름.
  12. 제8항에 있어서, 상기 필름이 폴리에스테르, 폴리프로필렌, 폴리아미드 및 폴리비닐 플루오라이드 필름으로 구성된 군에서 선택된 것인 캐리어 필름.
