The surface of a polyester optical film is coated with a coating. The formula contains 8-8.75wt% of acrylic graft modified polyurethane resin, 1.0-1.5wt% of crosslinking agent, and 1.95 by weight. 2.1wt% filled particle solution, 6.51wt% additive and 81.34-81.99wt% water solvent; among them, the composition of the filled particle solution contains surface-modified inorganic particles to improve the anti-sticking property of the coating The effect; the physical properties of the polyester optical film after the coating is high transparency, low haze, excellent anti-sticking, excellent adhesion and slippery properties, suitable for use as a backlight module of liquid crystal displays Substrate, for example, diffusion film or brightness enhancement film. |
