Surface protective films and optical laminates

Abstract

The objective of this invention is to provide a surface protective film that prevents deformation of the end of the adhered object and an optical laminate having the surface protective film. As a solution, the protective film of an embodiment of the present invention comprises a substrate film and an adhesive layer; the aforementioned protective film has a peel force of 0.025 N / 25 mm or more on an adhered object with a water contact angle of 70° or more and less than 90°; and a tensile shear force of 5.0 N or more in the in-plane direction on the adhered object; here, the tensile shear force in the in-plane direction on the adhered object is the breaking force measured according to JIS K 6850:1999.
