PROBLEM TO BE SOLVED: To obtain excellent glass scatter preventive properties by providing a release layer containing releasable polymer having siloxane bond as a main ingredient and having specific thickness on one side surface of a polyethylene naphthalate film having a specific thickness. SOLUTION: This laminated film comprises a release layer containing releasable polymer having siloxane bond as a main ingredient and a thickness of 0.005 to 0.2μm on one side surface of a polyethylene naphthalate film having a thickness of 4 to 150μm, and an adhesive layer provided on one side surface. The one side surface of the longitudinally uniaxially oriented naphthalate film of the release layer is coated with aqueous solution containing at least one type of polymer selected from a group consisting of silane coupling agent, silane coupling agent oligomer, silicone resin and modified silicone resin, dried and then heat treated at 150 to 260 deg.C after the orienting. |
