RADIATION CURABLE COATING COMPOSITION, LOW-REFRACTIVE-INDEX LAYER, AND ANTIREFLECTIVE FILM

摘要

The present invention relates to a radiation curable coating composition for forming a low-refractive-index layer, a low-refractive-index layer comprising a radiation cured product of the radiation curable coating composition, and an antireflective film comprising the low-refractive-index layer. The radiation curable coating composition for forming a low-refractive-index layer comprises: a photopolymerizable compound; inorganic microparticles; a polysilsesquioxane substituted with one or more reactive functional groups; a fluorine-based compound containing a photoreactive functional group; and a photopolymerization initiator, wherein 0.5-25 parts by weight of the polysilsesquioxane substituted with one or more reactive functional groups is contained on the basis of 100 parts by weight of the photopolymerizable compound.
