Document Type and Number:
WIPO Patent Application WO/2014/084154
Kind Code:
A1
Abstract:
[Problem] To provide: a multilayer film for producing a polarizing film, which is not susceptible to breakage during drawing even in cases where a thin PVA film is used therefor, and which is capable of easily producing a polarizing film having excellent polarization performance; and a multilayer film which is not susceptible to breakage during drawing even in cases where a thin PVA film is used therefor, and which is capable of very easily producing a polarizing film or the like having excellent polarization performance. [Solution] A multilayer film for producing a polarizing film, wherein a PVA film and a thermoplastic resin film are adjacent to each other and the bonding strength between these two films is 200 mN/15 mm or less; and a multilayer film wherein a PVA film and a thermoplastic resin film are adjacent to each other and the bonding strength between these two films is less than 1.5 mN/15 mm.
