PROTECTIVE FILM

摘要

PURPOSE: A protective film is provided to minimize temporal change of electronic ink when the protective film is used for an eBook, and to prevent aging of the film with low UV permeability. CONSTITUTION: An anti-glare coating layer(1) is formed on the first surface of a first transparent plastic substrate having the first surface and the second surface. A silicon oxide coating layer is formed on the first surface of a second transparent plastic substrate having the first surface and the second surface. The silicon oxide coating layer(3b) is formed on the first surface of a third transparent plastic substrate. The silicon oxide coating layer is formed with the thickness of 300 ~ 1,000Å.
