Abstract: A coating method includes coating a first coating composition including a heterogeneous photoinitiator having a first photoinitiator and a second photoinitiator on a substrate, irradiating ultraviolet rays having a first wavelength into the first coating composition to form a first coating layer and cure the first photoinitiator, coating a second coating composition on the first coating layer, and irradiating ultraviolet rays having a second wavelength different than the first wavelength into the second coating composition to form a second coating layer.
