A coated, highly transparent film based on cellulose triacetate, is proposed that includes a) a support film acting as support layer and a cellulose triacetate or a mixture of cellulose esters and cellulose triacetate as main component, the cellulose triacetate or mixture being defined by a haze value of <0.5%, measured on the cellulose triacetate or mixture drawn out to a film after having been dissolved in dichloromethane or acetone, and b) a multi-functional coating applied in a coating solution to one or both sides of the support film. A dissolver medium can also be used as an enclosure medium. The highly transparent films of the invention can be used as window film, sunglasses film, laminating film, furniture foil, enclosing film, slide film for microscopy, cover slip replacement film and/or protective film, adhesive to glass, wood, metal, ceramic, cellulose derivative films or plastics following incipient dissolution or heat treatment.
提出了一种基于三醋酸纤维素的涂布型高透明薄膜,它包括 a) 作为支撑层的支撑膜和作为主要成分的三醋酸纤维素或纤维素酯与三醋酸纤维素的混合物,三醋酸纤维素或混合物的雾度值小于 0.5%,这是在二氯甲烷或丙酮中溶解后拉成薄膜的三醋酸纤维素或混合物上测得的值,以及 b) 在支撑膜的一侧或两侧涂上涂层溶液中的多功能涂层。溶解介质也可用作封闭介质。本发明的高透明薄膜可用作窗膜、太阳镜膜、层压膜、家具箔、封闭膜、显微镜载玻片膜、盖玻片替换膜和/或保护膜、玻璃、木材、金属、陶瓷、纤维素衍生物薄膜或热处理后的塑料的粘合剂。
