<p>PROBLEM TO BE SOLVED: To provide a surface protective film that can achieve conflicting characteristics at high levels such as prevention of oligomer crystallization after heat treatment and adhesiveness to a functional layer, for example, a hard coat layer.SOLUTION: The surface protective film is obtained by applying a coating layer on one surface of a multilayer polyester film having a multilayer structure of at least three layers, in which a softening point of outermost surface polyester layers is higher than a softening point of an intermediate layer, and then forming a pressure-sensitive adhesive layer on the other surface of the film. The coating layer is formed from a coating liquid containing 70 wt.% or more of a crosslinking agent with respect to a nonvolatile component.</p> |
