    Abstract: The present invention relates to a curable composition for a glass substitute. By using a curable composition, excellent wear resistance and high hardness at a glass level can be obtained, and two-dimensional planar plastic film and three-dimensional plastic film without cracks or curls can be provided. The plastic films can be a substitute for existing glass, thereby enabling manufacturing of various electronic products, such as a display and the like, which are light and will not be easily damaged by external pressure.
