Kind Code:
A1
Abstract:
One embodiment of the present invention relates to a polymer film which contains at least a polymer of a polymerizable compound and an organic solvent-soluble resin, and wherein: the content ratio of the polymer is 70% by mass or more and the content ratio of the organic solvent-soluble resin is more than 1% by mass in a first surface-side surface layer part; the content ratio of the polymer is 50% by mass or less and the content ratio of the organic solvent-soluble resin is 35% by mass or more in a second surface-side surface layer part, said second surface being on the reverse side of the first surface; the organic solvent-soluble resin is present in a region that is positioned between the first surface-side surface layer part and the second surface-side surface layer part; and the content ratio of the polymer continuously changes from the first surface-side surface layer part toward the second surface-side surface layer part. Another embodiment of the present invention relates to a multilayer film, a method for producing a polymer film, a polarizing plate or an image display device.
