Leuco dyes, well-known multi-functional material, can exhibit excellent thermochromic properties by combining with developer molecule which is organic compound having a hydroxyl group and long alkyl chain. Our purpose of this research is to fabricate multifunctional material enabling control of both emission and coloration by combining leuco dye-developer system with emission materials. In this study, we investigated novel thermo-responsive dual-mode displaying media showing both reflective and emissive modes in red-green-blue (RGB) three primary colors. We employed the two kinds of leuco dye derivatives into the polymeric film as thermochromic material in order to improve the switching contrast of the emissive mode. As a result, we successfully demonstrated the control of coloration and emission in RGB colors with large contrast by thermal treatments.
