[0234] (a-1)
[0235] With 22.63g (0.2 mol) of ethyl cyanoacetate represented by the following structural formula [1], 3-oxobutyric acid ethyl ester represented by the structural formula [2] of 26.03g (0.2 mol) and 14.63g (0.2 mol) The n-butylamine represented by the structural formula [3] of ) was dissolved in 20ml of ethanol, and after dripping 6ml of piperidine, half reflux was carried out under stirring conditions for 26 hours. After the reaction solution was cooled, it was stirred in 200 ml of 10% hydrochloric acid aqueous solution, and then a solid was precipitated. After the precipitated solid was filtered and washed with water, it was suspended in 100 ml of hexane solution, filtered after stirring for about 30 minutes, and the filtrate was heated and dried in vacuum to obtain 11.3 g (yield 27.4%) of the following compound [4 ] (1-n-butyl-3-cyano-4-methyl-6-hydroxy-2-pyridone).

[0266] Suspend 18.61 g of the following citrazinic acid [7] in 500 ml of ethanol, drip 27 ml of concentrated sulfuric acid at room temperature under stirring, and then reflux for 4 hours. After the reaction solution was cooled, it was put into 1000 ml of water to precipitate solid. The precipitate was filtered, washed with water, and dried in vacuum to synthesize 14.88 g of the following compound [8] (67.7% yield).

[0291] Next, metal complex (60) to metal complex (73) were synthesized by the same method as the above-mentioned synthesis method, and a coating film was formed in the same manner as in Example 1, and the absorption spectrum of the coating film was measured. The maximum absorption wavelength (λmax) in solution (chloroform), the molar absorptivity, and the maximum absorption wavelength (λmax) of the coating film of these compounds were measured (octafluoro-n-pentanol was used as the coating solvent).
