Title:
DIARYLETHENE COMPOUND
Document Type and Number:
WIPO Patent Application WO/2018/038145
Kind Code:
A1
Abstract:
Provided is a diarylethene compound which does not require an additional component such as an acid for color development, while suitably exerting functions such as a switching function (coloring by means of ultraviolet light irradiation), excellent stability of a colored state under visible light, and irreproducible decoloring due to temperature increase in a low temperature environment (for example, room temperature or less).
A diarylethene compound which is represented by general formula (1).
