The present invention relates to a process for the trichromatic dyeing or printing of hydroxy-group-containing or nitrogen-containing organic substrates with dye mixtures and also to such dye mixtures and hydroxy-group-containing or nitrogen-containing organic substrates dyed or printed therewith.

Trichromatic dyeing process and dye mixtures used therein

According to the invention there are provided fiber-reactive dyestuffs which are compounds of the formula (I) wherein the substituents are defined as in claima process making the same and their use in dyeing or printing hydroxy-group-containing organic substrates.

Fiber-reactive mono-azo dyes

Fibre-reactive dyestuffs

Fibre-reactive asymmetrical triphenodioxazine compounds conform to the formula I ##STR1## where the individual symbols are as defined in the description, and mixtures thereof and are present in the form of a free acid or as salt. They are used as reactive dyes for dyeing or printing hydroxyl-containing or nitrogenuos organic substrates, such as leather or fiber material consisting of or comprising natural or synthetic polyamides or natural or regenerated cellulose; the most preferred substrate is textile material consisting of or comprising cotton.

Asymmetric triphenylenedioxazine compounds

Novel aluminium phthalocyanine compounds of having the formula ##STR1## and their salts wherein D represents --SO.sub.2 NR.sub.a --A--SO.sub.2 --B or ##STR2## --SO.sub.2 B is a fiber-reactive group and Z is a heterocyclic fiber-reactive group having 1 or 2 labile halogens selected from fluorine or chlorine. The novel aluminium phthalocyanine compounds and their salts are fiber-reactive dyestuffs useful in dyeing or printing hydroxy-group-containing or nitrogen-containing organic substrates.

Aluminum phthalocyanine reactive dyes

The invention is related to compounds of formula (I) ##STR1## their salts and mixtures thereof wherein the symbols are as defined in the specification are useful as fibre-reactive dyestuffs for dyeing or printing hydroxy-group-containing or nitrogen-containing organic substrates.

Fiber-reactive monoazo and disazo compounds of the formula

Fibre-reactive azo dyestuffs containing a halo substituted pyrimidine

Fibre-reactive monoazo compounds of the formula ##STR1## which compounds are in free acid or salt form, and mixtures thereof, are useful for dyeing or printing hydroxy group- or nitrogen-containing organic substrates, for example leather and fibre material comprising natural or synthetic polyamides or natural or regenerated cellulose; the most preferred substrate is a textile material comprising cotton.

Fibre-reactive monoazo dyestuffs

Fibre-reactive 1:1 copper complexes of the formula ##STR1## which compounds are in free acid or salt form, and mixtures thereof, are useful for dyeing or printing hydroxy group- or nitrogen-containing organic substrates, for example leather and fibre material comprising natural or synthetic polyamides or natural or regenerated cellulose; the most preferred substrate is a textile material comprising cotton.

Fibre-reactive monoazo copper complexes containing a halo substituted

Fibre-reactive monoazonaphthyl dyestuffs

Fibre-reactive disazo compounds of the formula ##STR1## which compounds are in free acid or salt form, and mixtures thereof, are useful for dyeing or printing hydroxy group- or nitrogen-containing organic substrates, for example leather and fibre material comprising natural or synthetic polyamides or natural or regenerated cellulose; the most preferred substrate is a textile material comprising cotton.

Fibre-reactive disazo dyestuffs

Dyes containing 5-cyano-2,4 or 4,6-dichloropyrimidyl fiber-reactive

Fibre-reactive formazan compounds, salts thereof or free acid forms thereof according to formula (I) ##STR1## in which R.sub.1 is hydrogen or --COOH, each of R.sub.2 and R.sub.4 is independently hydrogen, --COOH, --SO.sub.3 H, --NHCOCH.sub.3, --NHCOCHY.sub.2 --CH.sub.2 Y.sub.1, --NHCOCY.sub.2 .dbd.CH.sub.2 or --NHCOCH.sub.2 Y.sub.1,

Fibre-reactive copper-complex formazan compounds which contain a

Metal-free compounds of the formula ##STR1## and 1:1 and 1:2 metal complexes thereof and acid addition salts of such metal-free compounds and 1:1 and 1:2 metal complexes, wherein

The use of metal-free sulfo group free basic disazo compounds containing

Metal-free compounds of the formula ##STR1## a 1:1 or 1:2 metal complex of a metallizable compound of said formula or a salt of a metal-free compound of said formula or of a 1:1 or 1:2 metal complex thereof each cation of which is independently a non-chromophoric cation, or a mixture, thereof, wherein
