Additional patent to main patent No. 248806. Process for the production of a polyazo dye of the pyrazolone series. The subject of the present patent is a process for the production of a polyazo dye of the pyrazolone series. The process is characterized in that 2 moles of 1- diazo-6-nitro-2-oxy-naphthalene-4-sulfonic acid, 4 moles of 1- (4'-amino-phenyl)
- 8 - methyl - 5 -

arises. The new, metallizable tetrakisazo dye is a dark powder which dissolves in water with red and in concentrated sulfuric acid with an orange color and dyes cellulose fibers from the neutral Glauber salt bath in brownish-red tones, which after treatment with copper sulphate turns very red good overall fastnesses.
Pyrazolone, 2 mol of phosgene and 1 mol of the tetrazo compound of 1- (4'-amino-benzoyl-amino) -4-aminobenzene can act on one another in such a way that a tetrakisazo dye of the formula Example <I> 1: </I> 22 , 7 parts of 1- (4'-amino-bi'nzoylamino) -4-amino-benzene are in \ hydrochloric acid solution with 13.8.
Parts of sodium nitrite tetrazotized and the tetrazo compound, which has been blunted to a weakly congous acid reaction, in a bicarbonate medium with 139.8 parts of monoazo dye, obtained by one-sided coupling of 1- diazo - 6, - nitro - 2 -,
oxy. naphthalene-4-sulfonic acid. with -the urea of 1- (4'-arainö- phenyl) -3 - methyl - 5 - pyrazolons, _, combined. Then stir for a few hours at room temperature. After coupling is complete, the dye is precipitated with sodium chloride, filtered and dried.
, _ <I> .. _ _ Example 2: _- </I> 40.4 parts of urea from 1- (4'-aminophenyl) -3-methyl-5-pyrazolone are in a soda-alkaline solution with the. Intermediate product, prepared from the tetrazonium compound of <B> 22.7 </B> parts of 1- (4 '- imino-benzoylamino) -4-aminobenzene and 69.9 parts of monoazo dye:
1 -, 'Diazo, - 6: - nitrö - 21- @ ogy- naphthalene-4-sulfonic acid <B>) </B> - urea .des 1- (4' = amino phenyl) -3-methyl-5 -pyrazolons to the one-sided coupling product combined .. Is.
-no more _ diazo compound detectable, so one coupled with 29.5 parts of 1-diazo 6 - nitro-2- # ogyy-naphthalene-4-sulfonic acid in the same alkaline soda medium second.
The new tetrakisazo dye is precipitated, isolated and dried with salt. Furthermore, the same dye can also be obtained from the aminoazo compound:
1-Diazo-6-nitro-2-ogy-naphthalih-4-sulfonic acid 1- (4'-Amino-phenyl) -3-methyl-5-pyrazolone and the amino-azo compound that is obtained by coupling the intermediate product of tetrazotized 1- (4'-amino-benzoylamino) -4-amino-benzoi and the molar amount of the _ monoazo dye:
. 1-diazo-ss .-. Nitro-2-oxyraphthalene-4-sulfonic acid> urea of 1- (4'-aminophenyl) - 3 - methyl - 5-pyrazolone with 1- (9 = aminophenyl) Build-up -3-methyl-5-pyrazolone by condensation with the aid of phosgene in a soda-alkaline medium until no more free amino groups can be detected.
