Dyestuffs of the formula ##STR1## wherein D represents the radical of a diazo component;

5-chloro-4-fluoropyrimidinyl substituted diazopyridone

The preparation is described of compounds of the structure ##STR1## in which the substituents have the meanings indicated in the description. The compounds, which are in part new, are used as intermediate products for dyestuffs.

.beta.-phenoxyethylamines and their use for the preparation of dyestuffs

A polyazo reactive dyestuff of the formula ##STR1## wherein D=the radical of a diazo component of the formulae ##STR2## A and A'=H, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy or halogen, R and R'=H, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, halogen, CO.sub.2 H or SO.sub.3 H,

Polazo reactive dyestuffs

A new process for the preparation of substituted 2,4-diamino-6-flurotriazines of the formula ##STR1## in which the substituents have the meanings given in the description, comprises reacting ammonium salts of the formula ##STR2## in an aqueous medium at pH values of about 2.5-10 with 2,4,6-trifluorotriazine in a continuous process. The reaction products can be converted to dyestuffs without isolating the intermediates.

Process for the preparation of substituted

The preparation is described of compounds of the structure ##STR1## in which the substituents have the meanings indicated in the descripion. The compounds, which are in part new, are used as intermediate products for dyestuffs.

Beta-phenoxyethylamines and their use for the preparation of dyestuffs

Dyestuffs of the formula ##STR1## with the substituent meanings mentioned in the description, are suitable for dyeing and printing hydroxyl- and amido-containing textile materials. To prepare these dyestuffs, new intermediates of the formula ##STR2## are used.

Triphendioxazine dyestuffs

2,4-Dihydroxypyrimidines of the formula ##STR1## with the substituent meanings given in the description, are obtained by reacting pyrimidines of the formula ##STR2## with the substituent meanings given in the description, with aqueous alkalis at elevated temperature. 2,4,5,6-Tetrachloropyrimidine is obtained from the dihydroxypyrimidines by reaction with agents which replace hydroxyl by chlorine.

Process for producing 2,4,5,6-tetrachloropyrimidine by way of

The invention provides new reaction dyestuffs of the formula ##STR1## where n and m are each 0 or 1 such that n+m=1 or 2 and where

Aminonaphthol bisazo reactive dyes

Trisazo/azoxy dyestuff mixtures which in the form of free acid correspond to the formula ##STR1## in which R denotes H or optionally substituted alkyl,

Trisazo/azoxy dyestuff mixtures

Triphendioxazine dyestuffs of the formula ##STR1## where the substitutents are as defined in the descriptive part, produce blue to reddish blue dyeings of good light and wet fastness on cellulose and polyamide materials. The new dyestuffs are obtained by oxidative cyclization of condensation products of appropriately substituted amines of the formula ##STR2## with 1,4-benzoquinones.

Triphendioxazine vinyl sulphone dyestuffs

New dyes corresponding to the following general formula: ##STR1## wherein the substituents are as defined in the specification, are suitable for use in photographic recording materials.
