Highly transparent optical film |
abstract |
The present invention can provide a highly transparent optical film produced by using particles with no difference in refractive index in polyethylene terephthalate (PET), which is a commonly used polyester film, thereby having 1.5% or less haze and particles invisible to the naked eye so as to have high transparency, thereby being suitable for optical use and capable of improving rollability by forming a roughness of 4 nm or more. |
