The dyeing of cotton with hetero bi-functional reactive dyes containing both a monochlorotriazinyl and a chloroacetylamino reactive group

Water-soluble reactive dyes incorporating both a chloroacetylamino group and a monochlorotriazinyl group have been prepared. Under the alkaline application conditions employed, little or no additional fixation, via the desired nucleophilic displacement of chloride from the chloroacetylamino group, by cellulosate, was observed. The principal reaction was amide hydrolysis.
