摘要：
4-4'-Diamino derivatives of diphenylamine-2-sulfonic acid, stilbene-2,2'-disulfonic acid and benzanilide were used as potential substitutes for benzidine in the synthesis of disazo direct dyes. The relationship between structure and colour, dyeing and fastness properties of non-benzidine and benzidine disazo dir ect dyes has been studied. It can be concluded that dyes derived fr om benzanilide have superior substantivity and wash fastness on cotton compared to the other dyes studied. It was also found that dyes derived from diphenylamine-2-sulfonic acid and stilbene-2,2'-disulfonic acid have a similar colour on cotton to benzidine based dyes.
