Title:
OPTICAL-FILM MATERIAL, OPTICAL FILM, METHOD FOR MANUFACTURING POLARIZER, AND POLARIZER
Document Type and Number:
WIPO Patent Application WO/2014/148408
Kind Code:
A1
Abstract:
The present invention provides an optical-film material that allows the provision of a thin polarizer. Said optical-film material contains the following: a layer that comprises a stretched film having a surface that has been subjected to a rubbing treatment; an optically anisotropic layer; and an optically isotropic acrylic-polymer layer. The optically anisotropic layer is formed by polymerizing a liquid-crystal compound by shining light on a polymerizable composition that contains said liquid-crystal compound and has been directly applied to the abovementioned surface. The acrylic-polymer layer is formed by curing a (meth)acrylate-containing polymerizable composition that has been directly applied to the surface of the layer formed from the abovementioned polymerizable composition containing a liquid-crystal compound. The acrylic-polymer layer is thicker than the optically anisotropic layer. The present invention also provides the following: an optical film obtained by separating the stretched-film-comprising layer from the abovementioned optical-film material; a polarizer containing said optical film; and a manufacturing method therefor.
