| 초록 |
Disperse dyes derived from heterocyclic compounds such as phenylindole, pyridone, diaminopyridine,
and carbazole have been known to exhibit high light fastness and bathochromic shift compared
to the corresponding aminoazobenzene. The synthetic method to obtain diaminopyridine derivatives, which
can be used as coupling components, was chlorination of pyridone with phosphorous oxychloride, followed
by substitution with various primary amines. Four azo disperse dyes were synthesized by coupling four
diaminopyridines with 2-cyano-4-nitroaniline as a diazo component. Structures of these dyes were confirmed
by 1H NMR spectroscopy. The wavelengths of maximum absorption of the synthesized disperse dyes were
in the range of 517∼528nm, and molar extinction coefficients were 45,700∼50,100. The dyeability of four
disperse dyes toward PET fiber was generally good. Wash and rubbing fastnesses were excellent, while light
and dry heat fastness were good. |
