摘要：Disclosed is a method for producing an optical film composed of a transparentresin and a metal oxide, which film has high light transmittance and light diffusion
property even it is formed thin. Also disclosed is such an optical film. Specificallydisclosed is a method for producing an optical film having a total light transmittance ofnot less than 70% and a haze value of not less than 20%, which comprises a step (A)wherein a metal compound to form a metal oxide through a sol-gel reaction is subjectedto a sol-gel reaction in a solvent; a step (B) for providing a solution containing atransparent resin as a solute; a step (C) for mixing the mixture obtained in the step (A)with the solution obtained in the step (B); and a step (D) wherein the mixture obtained inthe step (C) is applied or spread over a substrate or container and then heated forevaporating the solvent, thereby forming a film thereon.
