Abstract: Disclosed is a panel for vehicles enabling a three-dimensional pattern to emit light including a panel body having a three-dimensional pattern portion having an engraved three-dimensional pattern on a rear surface thereof, a coating portion provided on an upper surface of the three-dimensional pattern portion, and a lighting portion disposed inside of the panel body configured to emit light to the panel body. The lighting portion includes a light guide plate provided at a position corresponding to the panel body, a light source provided on a side of the light guide plate, and a reflective sheet provided on an inner side of the light guide plate.

Abstract: Disclosed are an ink composition including light-absorbing nanoparticles and a photonic crystal structure formed using the same. The ink composition may include inorganic particles; monomer; photoinitiator; and nanoparticles light-absorbing nanoparticles to provide the photonic crystal structure. As consequence, problems such as low color sharpness, which makes photonic crystals visible, and attaining high productivity may be eliminated. Moreover, white scattering can be reduced, and thus a distinctive color can be exhibited even when there is a difference between a reflection angle and an observation angle of light, thereby improving visibility.
