摘要
本文对１８个吡啶酮偶氮染料，在不同条件（ｐＨ值、温度、溶剂）下的吸收光谱进行了研究。讨论了染料的结构、溶剂的种类、温度等对染料变色性能的影响。探讨了脱氰基吡啶酮系偶氮染料耐酸、碱变色的原因。
Sixty-eight pyridone azo dyes and C. I. Disperse Yellow 119 were synthesized. The relationship between the absorption spectra of dyes and the substituents in the diazo and coupling component was studied. The principle of the absorption spectra of the pyridone azo dyes is different from the general benzene azo dyes, the pyridone azo dyes which contain a 3-H group instead of a cyano group in the couplig component show more stability in acid-base media.
