| titleOfInvention | Low birefringence film, method for producing the same, and optical film |
| abstract | An optical film having reduced birefringence, which is a problem with a stretched film or the like, is provided. A multilayer biaxially stretched film having A layer / B layer / C layer, wherein the A layer contains 45 to 96% by mass of syndiotactic polystyrene and 55 to 4% by mass of polyphenylene ether, The layer contains atactic polystyrene, and the C layer contains 45 to 96% by weight of syndiotactic polystyrene and 55 to 4% by weight of polyphenylene ether, which gives the maximum refractive index in the film plane perpendicular to the thickness direction. When the refractive index in the direction nx is Nx, the refractive index in the direction ny perpendicular to the direction nx in the film plane perpendicular to the thickness direction is Ny, and the refractive index in the thickness direction nz is Nz, Nx and Ny The absolute value of the difference | Nx−Ny | is 0.05 or less, and the absolute value of the difference between the average value of the refractive indexes Nx and Ny and the refractive index Nz in the thickness direction nz | (Nx + Ny) / 2-Nz | is a low birefringence film of 0.05 or less.
