摘　　要：为了解决红色墨水染料耐光色牢度差问题,选择含偶氮H酸结构的红色墨水染料作为发色体,以C.I.活性红1为原料,与芳胺化合物缩合,合成含有不同光稳定片段的红色偶氮活性染料D1、D2、D3,采用质谱、红外光谱、紫外-可见光谱、核磁共振氢谱对合成染料进行表征。以结构相近的墨水染料C.I.活性红24∶1作为参照,分析合成染料的固色率、光致褪色率以及色牢度。结果表明:在C.I活性红1的分子结构中引入不同的光稳定片段后,含受阻胺光稳定片段染料D1的固色率降低,光致褪色率以及色牢度无明显变化;含苯并三唑紫外线吸收片段染料D2的固色率上升,光致褪色率和色牢度无明显变化;含氰基苯片段的染料D3的性能优异,固色率及耐光色牢度均有提升,光致褪色率降低。与常用红色活性墨水染料C.I.活性红24∶1相比,染料D3固色率接近,且耐光色牢度提高了1级。在染料结构中引入对UVB区域紫外线有强吸收的紫外线吸收片段更有利于提升染料耐光色牢度,对染料耐晒色牢度的提升有较好的应用价值。In order to solve the problem of poor color fastness to light of red ink dyes,azo H acid structure was selected as the chromophore of red ink dyes,and C.I.reactive red 1 was used as the raw material to synthesize red azo reactive dyes D1,D2,D3 containing different light stable segments by condensation with aromatic amine compounds.The synthesized dyes were characterized by mass spectrometry,infrared spectroscopy,ultraviolet visible spectroscopy and nuclear magnetic resonance hydrogen spectroscopy.With the ink dye C.I.reactive red 24∶1 with similar structure as a reference,the fixation rate,light induced fading rate and color fastness of the synthetic dye were compared.The results show that:after introducing different light stable segments into the molecular structure of C.I.reactive red 1,the fixation rate of the light stable segment dye D1 containing hindered amine decreased,while the light-induced fading rate and color fastness did not change significantly;the fixation rate of dye D2 containing benzotriazole ultraviolet absorption segment increased,while the light fading rate and color fastness did not change significantly;dye D3 containing cyanobenzene structure segment had excellent performance,and its fixation rate and light fastness were improved,while its light fading rate was reduced.Compared with the common red reactive ink dye C.I.reactive red 24∶1,dye D3 had similar fixation rate,and its color fastness to light was improved by 1 grade.The above results show that the introduction of UV absorption segments with strong absorption of UV rays in the UVB region into the dye structure is more conducive to improving the color fastness to light of the dye,and has good application value for improving the color fastness to light of the dye.
