A polyvinyl alcohol film and a process for producing the same |
| abstract |
To provide a PVA-based film not forming fine cracks or voids in a polarizing film even if increased in its draw ratio in order to obtain the polarizing film having a high degree of polarization for the purpose of achieving the high contrast of a liquid crystal monitor or television and capable of manufacturing the polarizing film of high quality in a high yield, and its manufacturing method. The PVA-based film has a three-layered structure wherein a core layer C is present between skin layers A and B and satisfies formula (I): DeltanMDA/DeltanMDB=1.0 to 1.5 and formula (II): DeltanMDB-DeltanMDC >= 0.2x10<-3> and at least either one of the formula (III): DeltanMDA < 3.0X10<-3> and the formula (IV): 0 <= |FA/FC-FB/FC| <= 0.1 (wherein DeltanMDA, DeltanMDB and DeltanMDC are each the birefringence in the length direction of the skin layer A, the skin layer B and the core layer C and FA, FB and FC are each the degrees of orientation of the skin layer A, the skin layer B and the core layer C). The manufacturing method of the PVA-based film is also disclosed. |
