Abstract
The present invention is suitable for optical applications with excellent transparency through a haze value of 1.5% or lower and particles that are hardly visible to the naked eye, by producing a film using particles having little difference in refractive index in polyethylene terephthalate (PET), which is a commonly-used polyester film, and can provide a highly transparent optical film capable of improving a winding property by forming surface roughness of 4 nm or higher.
