ORIENTED LAMINATED FILM

摘要

PROBLEM TO BE SOLVED: To provide a film which is long, can be wound up, is improved in adhesion and is suitable as a material for a polarizing plate or a liquid crystal display.

SOLUTION: An oriented laminated film is formed by laminating an A layer consisting of a thermoplastic resin and a B layer consisting of an alicyclic polyolefin resin using at least one of each. When the glass transition temperature of the thermoplastic resin is indicated by TgA(°C), that of the alicyclic polyolefin resin by TgB(°C), the average thickness of the oriented laminated film by T (μm), the total average thickness of the A layer by TS(μm) and the planar orientation coefficient of the A layer by P, the following relationships are satisfied: (a) TgA+10(°C)≤TgB(°C); (b) 0.03*TS<0.1*T; and (c) P≤1.0*10-3.
