PURPOSE: An ink composition forming a light diffusion layer is provided to output light from a light source for conversion to a crystal light pattern, thereby conveying aesthetic and pleasing light effects. CONSTITUTION: An ink composition forming a light diffusion by receiving light from a light source and outputting a crystal light pattern comprises: an ink binder which cures the light diffusion ink composition by comprising an epoxy resin and polyamide resin mixture; polymethylmethacrylate particles for comprising the crystal light pattern, and an ink solvent. The polymethylmethacrylate particles are polymethylmethacrylate beads of which the average particle diameter is 10-50 microns. The refractive index of the ink binder is 1.52, the refractive index of the PMMA particles is 1.49. |
