Abstract

윤활성, 내마모성과 투명성이 뛰어난 열가소성 수지필름 및 그 제조방법에 관한 것으로, 그 필름은 수지층에, 실리카와 실리카 이외의 무기 산화물의 1종 또는 2종 이상으로 이루어지는 특정의 복합산화물 미립자를 0.005∼20중량% 함유한다. 열가소성 수지는 폴리에스테르 필름인 것이 바람직하고, 열가소성 수지필름의 베이즈는 5% 이하인 것이 바람직하다. 이 열가소성 수지필름은 자기테이프, 콘덴서, 사진필름, 점착테이프, 등의 용도에 적합하다. 열가소성 수지필름은, 알칼리금속, 암모늄 또는 유기염기의 규산염과, 알칼리가용의 무기화합물을, pH 9 이상의 알칼리용액 중에 동시에 첨가하고, 이 반응액의 pH를 제어하지 않고 복합 산화물 미립자를 생성시켜서 얻어진 졸을, 열가소성 수지 및/또는 그 반응계에 첨가하여 필름가공하므로써 제조할 수가 있다.
