    摘要: A composite film is disclosed, comprising a protective layer comprising an adhesion-modified polyolefin film, a coating layer comprising the reaction product of a crosslinkable compound, an initiator, and a binder; and a polycarbonate layer; wherein the coating layer is disposed between the protective layer and the polycarbonate layer, and the peel strength between the protective layer and the polycarbonate layer, as measured both before and after thermal treatment or a combination of thermal and UV treatment of the composite film, is about 1 to about 20 centi-Newtons per centimeter measured using 180° angle peel measured at a peel rate of 25.4 cm/min. A method for forming a composite film, and an article comprising the composite film, are also disclosed.
