Abstract:
The problem to be solved by the present invention is to provide a protective adhesive film that can prevent damage to a polarized plate or the like caused by touch entry or the like even if disposed on the surface of the polarized plate without an interposed glass substrate. The present invention relates to a protective adhesive film comprising an adhesive layer with a thickness of at least 15 µm on at least one surface of a hard-coated film and having a total thickness of at least 150 µm, wherein the hard-coated film comprises a hard-coating layer on at least one surface of a resin film with a thickness of at least 130 µm, and the hard-coating layer has on the surface thereof a Martens hardness of at least 250 N/mm2, such hardness being measured by pressing a Vickers indenter that has face angles of 136° into the surface of the hard-coating layer with a load of 1 mN.
