The present invention relates to a base film, a laminate, and a method for producing a polarizing film. In the present invention, a substrate that can effectively produce a polarizing film having a thickness of about 10 μm or less, about 8 μm or less, about 7 μm or less, about 6 μm or less, or about 5 μm or less and having excellent functions such as polarization performance. A film, laminate or manufacturing method is provided. According to the present invention, it is possible to prevent the occurrence of breakage and curl during the stretching process and to easily stretch a polarizing functional material such as a PVA-based resin to produce a polarizing film. |
