Abstract
Disclosed is a film composed of a resin having a thiourethane bond, wherein the molar ratio (S/N) of sulfur to nitrogen contained in the resin is equal to or more than 0.8 and less than 3. A method for manufacturing a film is also disclosed. The disclosed film is excellent in a balance among high refractive index, low birefringence and light transmittance, and further excellent in a balance of mechanical characteristics such as toughness, hardness and dimensional stability, so that effects of deformation and the like during processing are very small, and the film is further excellent in solvent resistance as well.
