<p><P>PROBLEM TO BE SOLVED: To provide a surface protective film which provides a low peeling strength (low unwinding force) on own back side even by using a rubber-based pressure-sensitive adhesive and is excellent in adhesion reliability on an adherend, and to provide an optical film obtained by using the same. <P>SOLUTION: A surface protective film 1 has a pressure-sensitive adhesive layer 12 laminated to one side of a base layer 10 and a release treatment layer 14 laminated to the other side of the base layer 10, in which the pressure-sensitive adhesive layer 12 is formed of a rubber material, and the release treatment layer 14 is formed of an acrylic silicone graft polymer. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
