Abstract
Process for forming a fugitive dye comprises treating an aqs. soln. of an aromatic polyethoxylated cpd. (I) with excess HNO2 at pH 2-5 to form a diazonium salt directly and coupling this salt with a nucleophile (II) to form the dye. Neither metals nor strong acid solns. are necessary, and filtration of the reaction mixt. is not necessary, c.f. prior art processes. High yields are obtd. in reduced time. Fugitive dyes are used in colour-coding of textiles in prodn. and/or finishing processes to identify certain fibres, the dye being eliminated afterwards.
