摘要:
The present invention provides a polyvinyl alcohol film which has a width of 3 m or more, an in-plane retardation value of 30 nm or less and a fluctuation of in-plane retardation value of 15 nm or less.
摘要:
The present invention provides a polyvinyl alcohol film having a film thickness of 30 to 70 μm and a kinetic friction coefficient against a stainless-steel roll of 0.03 or less and a process for producing a polyvinyl alcohol film.
摘要:
The present invention provides a polyvinyl alcohol film having a correlation length of 200 nm or less, the correlation length being derived from the result of light scattering measurement using a He—Ne laser having a wavelength of 633 nm as a light source.
