Abstract

The present invention relates to a photocurable coating composition for forming a low refractive layer, a method for preparing an antireflection film using the photocurable coating composition, and an anti-reflective film prepared by using the photocurable coating composition. According to the present invention, a low refractive layer is formed of a photocurable coating composition containing two or more types of photo-polymerizable compounds, a photoinitiator, surface-treated hollow inorganic nanoparticles, and surface-treated solid inorganic nanoparticles.
