Abstract
A method of preparing a hard coating film by applying a first hard coating composition onto one side of a supporting substrate, performing a first photocuring by irradiating one side of the supporting substrate, applying a second hard coating composition onto the other side of the supporting substrate, performing a second photocuring by irradiating the other side of the supporting substrate which the second coating composition applied on, with ultraviolet having a first wavelength and a second wavelength longer than the first wavelength.
