| abstract |
The film of the present invention is composed of a resin having a thiourethane bond, and the molar ratio (S / N) of sulfur and nitrogen contained in the resin is 0.8 or more and less than 3, According to the present invention, the balance of high refractive index, low birefringence and light transmittance is excellent, and the balance of mechanical properties such as toughness, rigidity and dimensional stability is excellent, and the influence of deformation during processing is extremely small. A film having excellent solvent resistance is provided. |
