This invention suppresses the peeling force with respect to the adhesive layer of a separator by specifying thickness in the polyester base material which comprises the separator laminated | stacked on the optical surface protection film, and providing a cavity, and peelability and workability The excellent surface protection film for optics provided with the separator which can suppress generation | occurrence | production of the dents resulting from a separator by the separator which is excellent and also has excellent cushioning property. The optical surface protection film provided with the separator of this invention has a separator which has a separator in the surface opposite to the surface which contact | connects the optical surface protection film which has an adhesive layer on the at least single side | surface of a base film, and the adhesive layer of the said base film. It is an optical surface protection film provided, The said separator has a mold release layer and a polyester base material, The said polyester base material has a cavity, The thickness of the said polyester base material is 25-100 micrometers, The 180 ° gauge peel force with respect to the pressure-sensitive adhesive layer is characterized in that 0.7N / 50mm or less. |
