Reactive Mixed-anchor systems

Mixed-anchor systems in reactive dyes were first described in 1959. Such bifunctional dyes were first marketed in the early 1980s. These products are characterized by two anchors with differing reactivities a more reactive 2-sulfo-hydroxyethylsulfonyl group and a less reactive monochlorotriazinyl residue. An example of such a system is 14 ... [Pg.117]

An important step forward was achieved with the introduction of double- or multiple-anchor dyes. These can be homo- or heterofunctional (mixed-anchor systems). When dyes are provided with anchors of different reactivity, a wide range of dyeing properties can be realized. At the same time, process reliability and dyefastness are improved. Thus far, combination of the triazine and vinylsulfone anchors has had the best effect. [Pg.356]

Other mixed reactive systems have also been patented in addition to the double-anchor dyes so far described, including combinations of monofluorotriazine with difluorochloropyrimidine [32], alkoxychlorotriazine [33], or 2-(sulfothio) ethylsulfonyl groups [34], Other examples incorporate a difluorochloropyrimidine ring in conjunction with a vinylsulfonyl group [35],... [Pg.118]
