DIFFUSION PROTECTING FILM AND METHOD FOR PREPARING THE SAME

摘要

A diffusion protecting film is provided, which has advanced optical properties by embedding organic particle in the optical diffusion layer and is capable of preventing curling phenomenon by laminating optical diffusion layer after laminating prism protecting layer. The diffusion protecting film comprises: transparent plastic material(2); diffusion protecting film including optical diffusion layer(1) mixed organic particle with ultraviolet hardening resin which contains oligomer, monomer, photopolymerization solvent and organic solvent, which is laminated on the one side of the transparent plastic material at least. The method of manufacturing the diffusion protecting film comprises steps of: ultraviolet hardening by laminating prism protecting layer(3) on either side of a transparent plastic material(2); ultraviolet hardening by laminating optical diffusion layer(1) on the other side of the transparent plastic material(2).
