摘　　要：对硝基苯胺邻磺酸重氮盐与N-甲基γ酸偶合得单偶氮染料Ⅱ,再经还原,与三聚氯氰一缩,与牛磺酸二缩,与二乙醇胺三缩,最后经盐析,过膜后得墨水红原染料溶液。A monoazo dye was synthesized from 2-amino-5-nitrobenzenesulphonic acid diazonium salt and 4-hydroxy- 6-（ methyla mino） naphthalene-2-sulfonic acid by coupling reaction,the dye was reduced by Na2 S,and reacted with cyanuric chloride by firstcondensation; then,reacted with taurine by second-condensation,and reacted with diethanolamine by third-condensation; at last,an inkjet red was obtained by salting-out and membrane filtering.
