To 150 mL of NMP (N-methylpyrrolidone), 1.22 g of compound d-1-7 and 1.62 g of compound d-1-6 were added, followed by stirring at 70 C. for 3 hours under a nitrogen atmosphere. Then, 1.63 g of compound d-1-8 was added thereto, followed by stirring under heating at 160 C. for 8 hours. Then, 10.7 g of ammonium thiocyanate was added thereto, followed by stirring at 160 C. for 8 hours. After concentration, water was added, followed by filtration. The filtrate was purified by a silica gel column chromatography to obtain compound d-1-9, followed by adding the obtained compound to a mixed solvent of 30 mL of acetone and 40 mL of a 1N sodium hydroxide aqueous solution, and stirring for 24 hours at external temperature of 65 C. After bringing the temperature to room temperature, the pH was adjusted to 1.5 with hydrochloric acid, and the precipitate was filtrated, to give 3.3 g of crude product D-1-1a. (0270) This was dissolved in a methanol solution together with TBAOH (tetrabutylammonium hydroxide), and purified by SephadexLH-20 column. The fraction of the main layer was collected and concentrated, and then a solution of 0.1M trifluoromethanesulfonic acid was added thereto so as to adjust the pH thereof to 3, and the precipitate was filtered, thereby obtaining 2.4 g of exemplified dye D-1-1a. (0271) The structure of exemplified dye D-1-1a obtained was confirmed by MS measurement. (0272) MS-ESI m/z=928.1 (M-H)+
