吡啶酮系偶氮型分散染料结构与性能的研究──Ⅰ．吡啶酮系偶氮型分散染料结构与光谱性能的关系

Study of the Structures and Properties of Pyridone Azo Disperse Dyes

本文合成了６８个吡啶酮偶氮型分散染料及Ｃ．Ｉ．分散黄１１９，研究了重氮组份及偶合组份上取代基与染料光谱性能的关系。吡啶酮系偶氮染料光谱性能规律和一般苯系偶氮染料光谱规律不同，并且脱氰基吡啶酮分散染料较含氰基吡啶酮分散染料有好的耐酸、碱变色性。

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.
