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
