(57) [Summary] [Structure] A sulfonated diarylethene compound having a conjugated double bond chain represented by the following general formula (1). [Chemical 1] (However, in the formula, n represents an integer of 2 to 5. A is a general formula (2) R 1 and R 2 are alkyl groups, and R 3 to R 6 are hydrogen atoms, alkyl groups, dialkylamino groups or alkoxy groups. B is represented by the general formula (3): R 7 represents an alkyl group, and R 8 to R 15 represent a hydrogen atom, an alkyl group, a dialkylamino group, an alkoxy group, a cyano group or a nitro group. [Effect] It is possible to obtain a reversible optical recording material having excellent heat stability, moisture resistance, sensitivity, and photochromic properties with good durability against repeated coloring and decoloring, and the like. |
