LIGHT DIFFUSIVE INK COMPOSITION AND LIGHT GUIDE PANEL UNIT USING THE SAME

摘要

PURPOSE: A light diffusive ink composition makes an aesthetic feeling by outputting milky or cloudy light and obtains illumination light with clear and beautiful design by a light guiding panel in a glass material. CONSTITUTION: A light diffusive ink composition comprises an ink binder which includes one of an epoxy resin and a polyamide resin and cures the light diffusive ink composition by being mixed with the other; a light diffusing agent selected from silicone beads or silica; and an ink solvent. The light diffusing agent has an average granularity of 0.8-4 μm. A light guiding panel (110) includes a light-diffusing layer formed by the light diffusive ink composition; and a light guiding member (111) in a glass material, having the light-diffusing layer.
