Summary:To provide a benzotriazole-based compound which is useful as a light absorber.SOLUTION: Provided is a triazole-based compound represented by formula (1A). (In the formula, R1 and R2 each independently represent a halogen atom, a cyano group, a hydroxyl group, a sulfone group, a substituted or unsubstituted alkyl group, and the like; n represents an integer of 2 or more; L represents an n-valent linking group; n1 represents an integer of 0-4, n2 represents an integer of 0-4, and n1+n2 is 0-7; when a plurality of R1's are present, the plurality of R1's may be the same or different and may be bonded to each other to form a ring; and when a plurality of R2 are present, the plurality of R2 may be the same or different and may be bonded to each other to form a ring.)SELECTED DRAWING: None 【課題】光吸収剤として有用なベンゾトリアゾール系化合物を提供する。【解決手段】式(1A)で表されるベンゾトリアゾール系化合物。JPEG2024039652000064.jpg34112(式中、R1及びR2は、それぞれ独立に、ハロゲン原子、シアノ基、水酸基、スルホン基、置換若しくは無置換のアルキル基等を表す。nは2以上の整数を表し、Lはn価の連結基を表す。n1は0~4の整数を表し、n2は0~4の整数を表し、n1+n2が0~7である。R1が複数存在する場合において、複数のR1は、同じであっても異なっていてもよく、互いに結合して環を形成してもよい。R2が複数存在する場合において、複数のR2は、同じであっても異なっていてもよく、互いに結合して環を形成してもよい。)【選択図】なし
