PRINTING INK COMPOSITION FOR LIGHT DIFFUSION PLATE OF LIGHT DEVICE AND LIGHT DIFFUSION PLATE OF LIGHT DEVICE PREPARED BY USING THE SAME

摘要

PURPOSE: An ink composition for printing a light diffusion plate for illumination is provided to print various patterns and designs without the degradation of light transmissivity on the light diffusion plate for illumination. CONSTITUTION: An ink composition for printing a light diffusion plate for illumination comprises: 25~35 weight% of an acrylic resin; 6~25 weight% of a light diffusion agent selected from the group consisting of silica(SiO2), silicone beads, and polymethylmethacrylate beads; and 40~60 weight% of a solvent. The acrylic resin is synthesized by mixing acrylate-based monomers, organic solvents and reactive initiators through a solution polymerization method. The diameter of silica(SiO2), silicone beads, and polymethylmethacrylate beads is 0.7~8 micron.
