(a) Field of the Invention
The present invention relates to a plastic film. More particularly, the present invention relates to a plastic film which exhibits high hardness, impact resistance, self-healing property and excellent processability.
The plastic film of the present invention includes
a support substrate; and
a coating layer formed on at least one side of the support substrate, including a crosslinked copolymer, in which a tri- to hexafunctional acrylate-based monomer and a caprolactone group-containing multifunctional acrylate-based compound are copolymerized at a weight ratio of 5:5 to 8:2, and an inorganic fine particle dispersed in the crosslinked copolymer.
