Abstract

이상과 같이 본 발명은 입자를 함유하는 열가소성수지 A로서 이루어지는 층(A)을 열가소성수지 B로서 이루어지는 층(B)의 적어도 한표면에 적층하여 이루어지는 2측 배향열가소성 수지필름이다.
상기한 필름은 A층의 두께 "t"와 열가소성수지 A에 함유된 입자의 평균직경 "d"의 특정비 t/d, A층의 표면에 존재하는 돌기중 0.7-2.6㎛의 직경을 갖는 돌기의 특정수 및 상기한 범위의 직경을 갖는 돌기수 L에 대한 더 작은 직경을 갖는 돌기수 S의 특정비 L/S를 보유한다.
상기 필름은 권취시 우수한 권취성 및 비데오 테이프에 사용될 때 우수한 내더빙성을 얻을 수 있다.
