Abstract
This invention discloses an anti-glare film comprising a recycled PET substrate and an anti-glare coating disposed on the recycled PET substrate, wherein the recycled PET contains at least 50% recycled PET resin, and the anti-glare coating comprises an acrylic binder resin and a plurality of amorphous inorganic microparticles. The anti-glare film of this invention forms an uneven surface on the surface of the anti-glare coating by the amorphous inorganic microparticles, which can effectively shield impurity particles and / or microbubbles in the recycled PET film material for application in displays.
