<p><P>PROBLEM TO BE SOLVED: To provide an inexpensive surface protective film which is excellent in the ability to protect an adherend (especially an optical sheet) and capable of carrying out an inspection of a defect on the adherend (in particular, the optical sheet) in high resolution, at the state that a surface-protective film (a pressure-sensitive adhesive sheet) is adhered to the adherend. <P>SOLUTION: The inexpensive surface protective film which prevents the adherend (especially optical members, such as optical sheet) from being electrostatically charged during processing or transportation of the adherend (in particular, optical sheet), is provided. A removable pressure-sensitive adhesive sheet which comprises a pressure-sensitive adhesive layer formed on one side of a base layer thereof, and the anti-static layer on the surface of the other side, is characterized in that the anti-static layer above described contains a polymer type anti-static agent comprising an olefin block and a hydrophilic block. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
