FLUORESCENT DYE COMPOUND HAVING BENZOTHIADIAZOLE STRUCTURE AND WAVELENGTH CONVERSION-TYPE SEALING MATERIAL COMPOSITION USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a fluorescent dye compound being excellent in processability, optical property/stability and suppressing precipitate generation, and a wavelength conversion-type sealing material composition using the same.;SOLUTION: A fluorescent dye compound is represented by the general formula. X₁ and X₂ each independently represent -O-, -(C=O)O-, -O(C=O)-, -CH₂O-, CH₂O(CO)-or a single bond, Y₁ and Y₂ represent each independent or substituted alkyl group with a carbon number of 2 to 18 having a carbon-carbon double bond group, Z₁ and Z₂ represent each independent or substituted alkyl group with a carbon number of 1 to 18 (for Y1, Y2, Z1 and Z2, a non-adjacent C atom in the alkyl group may be substituted by an O atom) or the like, m, n, o and p each independently represents an integer of 0 to 4 (both m+n and o+p are 4 or less).;COPYRIGHT: (C)2015,JPO&INPIT
