This article describes recent research progress in colorants and liquid crystals developed by FUJIFILM Corporation. Recent topics in colorants based on three key technologies are as follows; 1)application of photo-induced energy conversion technology to dyes for DVD, 2)development of dye for Dye Diffusion Thermal Transfer (D2T2) and inkjet printing system based on chromogenesis technology, and 3)syntheses of new heterocyclic compounds such as 2-aminopyrroles for useful intermediates and triazines for UV absorbers. Liquid crystal technology from the representative discotic compound is directed toward four areas that are 1)synthetic technology for stable supply of the discotic compound on an industrial scale, 2)new functional materials using discotic liquid crystals such as ubricants, 3)expansion to calamitic liquid crystals for “selective reflective type” color filter for LCD, and 4)application to guest-host liquid crystal mode. In the last part “base and core technology” of organic materials owned by FUJIFILM is introduced. We are continuously studying to produce innovative materials with the key message “Change the world with light and color”.
