Reactive azo dyes carrying two amine-fluoro-triazinyl groups for dyeing and printing cotton

摘要

Reactive dyes of the formula (1) in which D is the radical of a diazo component of the benzene, naphthalene, azobenzene, naphthylazobenzene, azonaphthalene or phenylazonaphthalene series, K is the radical of a coupling component of the benzene or naphthalene series or of the heterocyclic series, except a pyrazolone radical, R1 and R2, independently of each other, are each hydrogen or an unsubstituted or substituted C1-4-alkyl radical, and X1 and X2, independently of each other, are each unsubstituted or substituted aminofluoro-s-triazinyl, are particularly suitable for dyeing and printing cellulose-containing fibre materials and produce, in high dyeing yield, dyeings and prints having good fastness properties.
