Abstract

The present invention relates to an ultra-hydrophilic antireflective coating composition, to an ultra-hydrophilic antireflective film using the same, and to a method for preparing the ultra-hydrophilic antireflective film, wherein the ultra-hydrophilic antireflective coating composition can form a coating layer having a low refractive index and ultra-hydrophilicity. More particularly, the present invention relates to an antireflective film and to a method for preparing same wherein the antireflective film has excellent hydrophilicity and minimize the reflectivity by forming the coating layer using an ultra-hydrophilic antireflective coating composition including a siloxane compound as a binder. The ultra-hydrophilic antireflective film using the ultra-hydrophilic antireflective coating composition has excellent antireflective effects and a self-cleaning function. Therefore, it is expected that the ultra-hydrophilic antireflective film can be applied to various display devices such as devices for the outdoors.
