摘要： Reactive dyes of formula in which D is a residue of a dyestuff of the perinone or naphthoylene - dibenzimidazole series, X is an -SO2NH- or -SO2NHRNH-SO2- bridge, R is an aliphatic or aromatic residue, Y is a hydrogen atom or a sulpho group and n is a positive integer are prepared by reacting a sulphochloride of a perinone or naphthoylene-benzimidazole compound with an amine of formula in which Y is as above or by reacting the sulphochlorides with aliphatic or aromatic diamines the products of which reaction are then treated with sulphochlorides of formula in which Y is as above. Alternatively the perinone or naphthylene-benzimidazole sulphochlorides are condensed with mono-acetyldiamines followed by deacetylation and treatment with the 2-chloro-benzthiazole-sulphochlorides above. Orange-brown-yellow shades are obtained in cotton materials by conventional dyeing processes.
