Dyestuff mixtures containing one or more dyestuffs of the formula ##STR1## and one or more dyestuffs of the formula ##STR2## in which the substituents have the meanings given in the description are highly suitable for producing green cotton dyeings.

Dyestuff mixtures of metal phthalocyanine and pyridone azo reactive dyes

Novel reactive dyestuffs of the formula ##STR1## having the substituent meanings specified in the description are highly suitable for dyeing and printing hydroxyl- and amido-containing textile materials. They produce very fast dyeings and prints in high yields.

Reactive phthalocyanine dyestuffs

Novel reactive dyestuffs of the formula ##STR1## wherein Pc=radical of a Cu- or Ni-phthalocyanine,

Reactive phthalocyanine dyestuffs containing a fluorochloropyrimidinyl

Basic copper-phthalocyanine dyestuffs of the formula ##STR1## in which Cu--Pc denotes the radical of an x-valent copper-phthalocyanine,

Copper-phthalocyanine dyestuffs

Basic copper phthalocyanine dyestuffs of the general formula ##STR1## in which Cu-Pc denotes the radical of an m+n-valent copper phthalocyanine radical,

Cu-Pc dyestuffs

Dyestuffs of the formula ##STR1## wherein the substituents have the meaning indicated in the description, and their use for dyeing and printing materials containing hydroxyl groups or amide groups, such as textile fibres, filaments and fabrics of wool, silk or synthetic polyamide or polyurethane fibres and for dyeing and printing natural or regenerated cellulose with dyeings and prints which are fast to washing. The dyeings obtained with the dyestuffs are distinguished by good to very good fastness properties, in particular by outstanding fastness to wet processing.

Phthalocyanine reactive dyestuffs, their preparation and their use for

Aqueous solutions of copper phthalocyanine-sulphonic acid salts of the formula ##STR1## in which Cu--Pc a copper phthalocyanine radical,

Dyestuff solutions, their preparation and their use for dyeing paper

In order to dye and print cellulose fibres swollen with water-miscible swelling agents or fibre blends containing these fibres, the fibres are treated with a dyestuff of the general formula ##STR1## wherein Pc denotes the radical of a Cu phthalocyanine,

Process for dyeing and printing cellulose fibres

Dyestuffs of the formula ##STR1## wherein Pc, R.sub.1, R.sub.2, R.sub.3, R.sub.4, Ar, R.sub.5, R.sub.6, a, b and c have the meaning indicated in the description, and their use for dyeing and printing materials which contain hydroxyl or amide groups, such as textile fibres, filaments and fabrics made of wool, silk and synthetic polyamide and polyurethane fibres and for wash-fast dyeing and printing of natural or regenerated cellulose.

Phthalocyanine reactive dyestuffs

Phthalocyanine reactive dyestuffs of the formula ##STR1## wherein Pc, R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, B, R.sub.6, R.sub.7, R.sub.8, a, b and c have the meaning indicated in the description, and their use for dyeing textile materials containing hydroxyl groups and textile materials containing nitrogen, in particular textile materials made of natural and regenerated cellulose and furthermore made of wool, silk and synthetic polyamide fibers and polyurethane fibers. The resulting dyeings are distinguished by excellent fastness to wet processing.

Reactive dyestuffs

Phthalocyanine dyestuffs of the formula ##STR1## wherein Pc denotes the radical of a copper phthalocyanine or nickel phthalocyanine,

Process for the preparation of phthalocyanine reactive dyestuffs

Dyestuff solutions of copper phthalocyanine derivatives for paper dyeing

The invention relates to water-insoluble quinophthalone dyestuffs of the formula ##STR1## in which T represents W--Ar or ##STR2## and Ar denotes aryl,

Quinophthalone dyestuffs

Polycyclic dyestuffs free from sulphonic acid groups of the formula ##STR1## in which A denotes an arylene radical and

Polycyclic dyestuffs

Phthalocyanine reactive dyestuffs of the formula ##SPC1## Wherein Pc, R.sub.1, R.sub.2, R.sub.3 -R.sub.5, a, b and c and Z have the meaning given in the description. They are outstandingly suitable for dyeing and printing materials containing cellulose, such as natural and regenerated cellulose, in accordance with the techniques known for the purpose. The new dyestuffs are also suitable for dyeing materials containing amide groups, such as wool, silk and synthetic polyamides. Dyeings obtained on textile cellulose, in particular, distinguish themselves by very good fastness properties, especially fastness to light and to wet processing.
