Mixture of water soluble reactive azo dyes, process to manufacture same and its use

摘要

Dye mixtures contain azo dyes comprising 1-(2-vinylsulfonylphenylamino-4-substituted-1,3,5-triazin-6-amino)-2-( mono- or di-sulfonaphth-2-yl-azo)-8-naphthol-3,6-disulfonic acid(s) (I) and 1-(2-vinylsulfonylphenylamino-4-substituted-1,3,5-triazin-6-amino)-2-( vinylsulfonylphenyl-azo)-8-naphthol-3,6-disulfonic acid(s) (II) or vinyl precursors, in acid or salt form. Dye mixtures contain azo dyes comprising 1-(2-vinylsulfonylphenylamino-4-substituted-1,3,5-triazin-6-amino)-2-( mono- or di-sulfonaphth-2-yl-azo)-8-naphthol-3,6-disulfonic acid(s) of formula (I) and 1-(2-vinylsulfonylphenylamino-4-substituted-1,3,5-triazin-6-amino)-2-( vinylsulfonylphenyl-azo)-8-naphthol-3,6-disulfonic acid(s) of formula (II) or vinyl precursors, in acid or salt form: p = 1 or 2; X<1>, X<2> = fluorine, chlorine, NR<3>R<4> or OR<3>; R<1>, R<1>', R<2>, R<3>, R<4>. R<5>, R<6> = hydrogen (H) or substituents; Y, Y<1>, Y<2> = vinyl (precursor). The full definitions are given in the DEFINITIONS (Full Definitions) Field. Independent claims are also included for: (a) a method of preparing the mixtures by mechanical mixing of (I) and (II) in solid or liquid form; and (b) a method of preparing the mixtures by condensation and coupling reactions.
