摘要
本文合成了４，４′－二氨基苯磺酰替苯胺，并且以该中间体合成了十只黑色直接染料。选出其中三只染丝绸，色度５％的黑色与直接黑ＢＮ相近，皂洗牢度及耐光牢度都优于直接黑ＢＮ。
?Diamino phenylsulfanilamido aniline and black dyes containing 4,4′-diamino phenylsulfanilamido aniline as intermediate were synthesized.Three black dyes among them were used on colouring silk and leather.Their blackness is similar to that Direct Black BN when their o.w.f.is 5%.Their fastness of light and soap washing are better than that of Direct Black BN.
