Reactive dye mixtures, used for dyeing and printing fibrous material with hydroxyl or carbonamido groups, contain mono- and di-sulfonated amino-naphthol disazo and optionally monoazo dyes

摘要

Reactive dye mixtures contain 8-amino-2,7-disazo-1-naphthol-3,5(6)-disulfonic acid dye(s) (I) and 6-amino-1,5-disazo-1-naphthol-3-sulfonic acid dye(s) (II) and optionally monoazo-naphthol, -naphthylamine and/or -aminonaphthol dye(s) (III), each with specified fiber-reactive group(s). Reactive dye mixtures contain 8-amino-2,7-disazo-1-naphthol-3,5(6)-disulfonic acid dye(s) (I) and 6-amino-1,5-disazo-1-naphthol-3-sulfonic acid dye(s) (II) and optionally monoazo-naphthol, -naphthylamine and/or -aminonaphthol dye(s) (III), each with fiber-reactive group(s) -SO 2Z or -Z 2. [Image] [Image] [Image] D 1 - 5substituted carbamoylphenyl or optionally substituted phenyl, naphthyl or amino-sulfo-phenyl. Mixtures containing (I; where D 1, D 2 = phenyl or sulfophenyl with a -SO 2Z group) and (III; where R*, R** = H or 1-4 C alkyl) are excluded. The full definitions are given in the DEFINITIONS (Full Definitions) Field. Independent claims are also included for the following: (1) Three methods of preparing the dye mixtures. (2) Aqueous liquid preparations containing one of these dye mixtures, with a total dye content of 5-50 wt.%.
