Zusammenfassung: | To provide an optical filter useful for a display device or the like.SOLUTION: The present invention provides an optical filter containing a compound represented by formula (I) [where R-Rindependently represent a hydrogen atom or an optionally substituted C1-6 monovalent hydrocarbon group. Tand Tindependently represent a hydrogen atom or an optionally substituted C1-6 monovalent hydrocarbon group. One of Yand Yis an optionally substituted monovalent aromatic group and the other is an optionally substituted monovalent aromatic group, a hydrogen atom, a halogen atom or an optionally substituted C1-6 monovalent hydrocarbon group (the hydrocarbon group is a group other than a monovalent aromatic group, -CH- included in the hydrocarbon group is optionally substituted with -O- or -CO-)].SELECTED DRAWING: None
【課題】表示装置等に有用な光学フィルタを提供する。【解決手段】式(I)で表される化合物を含む光学フィルタ。[式中、R1〜R4は、それぞれ独立して、水素原子又は置換基を有していてもよい炭素数1〜6の1価の炭化水素基を表す。T1及びT2は、それぞれ独立して、水素原子又は置換基を有していてもよい炭素数1〜6の1価の炭化水素基を表す。Y1及びY2は、いずれか一方が置換基を有していてもよい1価の芳香族基を表し、他方が置換基を有していてもよい1価の芳香族基、水素原子、ハロゲン原子又は置換基を有していてもよい炭素数1〜6の1価の炭化水素基(該炭化水素基は1価の芳香族基以外の基であり、該炭化水素基に含まれる−CH2−は、−O−又は−CO−に置き換わっていてもよい。)を表す。]【選択図】なし |
