PROBLEM TO BE SOLVED: To provide a novel fluorescent material having absorption in a high heat resistance and high compatibility ultraviolet to visible short wavelength region. SOLUTION: General formula (I) [Chemical 1] Wherein X 1 , X 2 , X 3 and X 4 are the same or different and are a hydrogen atom or an alkyl group having 1 to 8 carbon atoms, an alkoxy group having 1 to 8 carbon atoms, an amino group or an alkyl group having 1 to 8 carbon atoms. An alkylamino group having an alkyl group, a dialkylamino group, and Indicate R 1 and R 2 are the same or different and each represents a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, Y represents O, S or NR 3 R 4 , R 3 and R 4 are the same or different and each represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms; m represents 0 or 1, n represents 0, 1 or 2) Provided is a fluorescent material-containing metal foil-clad laminate containing the above compound.
