HIGHLY SCRATCH-RESISTANT FILM FOR PREVENTING ADHESION OF STAIN

摘要

PROBLEM TO BE SOLVED: To provide a highly scratch-resistant film for preventing the adhesion of stain which is arranged on the surface of an object having to be prevented from the adhesion of the stain and the occurrence of a scratch not only to prevent surface staining but also to reduce an external impact.

SOLUTION: The highly scratch-resistant film for preventing the adhesion of a stain is obtained by laminating an inorganic thin film layer and a water repelling resin layer on a base film in this order and the inorganic thin film layer is formed by a vacuum film forming method while the water repelling resin layer is composed of a fluororesin having a silicon atom at the terminal of the polymer main chain thereof. By this constitution, the silicon atom positioned at the terminal of the polymer main chain of the fluororesin constituting the water repelling resin layer is bonded to the constituent atom of the inorganic thin film layer to enhance the adhesion of the water repelling resin layer and the inorganic thin film layer. The adhesion of the stain to the water repelling resin layer is prevented by the fluororesin, the coefficient of surface friction of the water repelling resin layer is reduced by the fluoroplastic to reduce the impact due to foreign matter to the film.
