以6—羟基—2—吡啶酮衍生物作为偶合组份,取代芳胺作为重氮组份的吡啶酮系偶氮染料是黄至橙色调的分散、活性和酸性染料的重要品种。程侣柏等及Cee等用红外和核磁共振波谱证明,它们是以腙体构型存在的。用~(1)H、~(13)C核磁共振波谱和紫外—可见光谱证
Pyridone-based azo dyes with 6-hydroxy-2-pyridone derivatives as coupling components and substituted aromatic amines as diazo components are important yellow-orange dispersions, active and acid dyes. Cheng et al. And Cee et al. Demonstrated by infrared and nuclear magnetic resonance spectroscopy that they exist in the hydrazone configuration. ~ (1) H, ~ (13) C nuclear magnetic resonance spectroscopy and UV-Vis spectroscopy
