ANTIREFLECTIVE COATING COMPOSITION, ANTIREFLECTIVE FILM, AND PREPARATION METHOD THEREOF

摘要

The present invention relates to an antireflective coating composition which is divided into at least two layers through phase separation after single layer coating, and more specifically, to an antireflective coating composition comprising hollow particles surface-coated with a fluorine-based compound having a refractive index of 1.3-1.4 and a surface tension of 10-25 mN/m, an antireflective film prepared therefrom, and a preparation method thereof. The antireflective coating composition according to the present invention allows at least two layers to be spontaneously formed even with one coating process by smooth phase separation within a coating layer. Particularly, since the interface of each layer formed by phase separation is actually chemical bonded or crosslinked, delamination of each layer can be minimized. In addition, a film having excellent scratch resistance and antireflection can be prepared with a more simplified method by using the antireflective coating composition according to the present invention.
