摘要：The properties and the diazotisation process of 1-ethyl-5-cyano-6-hydroxy-4-methyl-5-amino-2-pyridone were described. The conditions of the coupling reaction were also discussed and a series of new azo dyes using 1-ethyl-5-cyano-6-hydroxy-4-methyl-3-amino-2-pyridone as diazo components were synthesized. The absorption properties of these new azo dyes were investigated in various solvents and the mixture solvent of chloroform/DMSO with different volume ratios. (C) 2002 Elsevier Science Ltd.
