Abstract
The present application relates to a high-refractive composition. The composition of the present application exhibits excellent transparency, moisture resistance, heat resistance, water resistance, weather resistance, light resistance, and durability, and enables formation of a highly refractive film having a high index of refraction. The composition exhibits little outgassing during or after a process and can be applied to a solution application method, and thus can be effectively used in various electronic optical devices.
