  Gegenstand vorliegenden Patentes ist     ein     Verfahren zur     Darstellung        eines        chromier-          baren        Monoazofarbstoffes,        dadurch    gekenn  zeichnet, dass     man        diazotierte        2-A.mino-4-di-          isobutylphenol-6-sulfonsäure    mit     3-Methyl-5-          pyrazolon;    kuppelt..  



  Der neue Farbstoff stellt ein rotes Pulver  dar, dessen Lösung in Wasser orange, in  Schwefelsäure gelborange gefärbt ist. Er      färbt Wolle in gelben, beim Behandeln mit       Chromsadzen    nach rot umschlagenden Tönen.       Beisrriel:     30,1 Teile aus     4-Diisobutvlphenol    durch       Sulfonierung,        Nitrierung    und Reduktion dar  gestellte     2-Amino-4-diisobutylphenol-6-sul-          fonsäure    werden indirekt     diazotiert    und die       Diazoniumverbindung    mit 9,

  8 Teilen     3-lle-          thyl-5-pyrazolon        sodaalkalisch    gekuppelt. So  bald die     Farbstoffbildung    beendigt ist, wird  der Farbstoff in üblicher Weise aufgearbei  tet.

      Yeilahr en to the representation of an honorable monoazo dye. It has been found that valuable chromable - "# lonoazofa dyes are obtained if one:

  diazotized 2-aminophenod-6-sulfonic acids which contain a cycloalkyl radical or an alkyl radical of 3 to 8 carbon atoms in the 4-position, couples with pyrazolones without free sulfonic and carboxylic acid groups.



  When. p-alkylated o-aminophenolsulphonic acids according to the definition, which are prepared from the corresponding alkylphenols by sulphonation, nitration and reduction according to known methods, can be used, for example:

         2-Amino-4-nsopropylphenol-6-sulfonic acid, 2-amino-4-tert-butylphenol-6-sulfonic acid, 2 amino. - 4 - n. Butylphenol - 6 - sulfonic acid, 2 - amino - 4 - tert. amylphenol - 6 - sulfonic acid, 2 - amino-4-, diisobutylphenol-6-sulfonic acid, 2 - amino-4-cyclohegylphenol-6-sulfonic acid etc.



  As coupling components come z. B. the following pyrazodones in question: 3-methyl-5-pyrazolone, 1-phenyl-3-methyl-5-pyrazolone, 1- (2'-methylphenyl) -3-methyl-5-pyrazolone, 1-phenyl-3- methyl-5-pyrazolone-3'- or -4'-sulfonamide, 1- (2'-chlorophenyl) -3-methyl-5- pyrazodone, 1 @ (3'- or 4'-chlorophenyl)

  -5- pyrazolone - 3-carboxylic acid ethyl ester, 1- (3'-chlorophenyl) -5-pyrazolone-3-carboxamide, 1, - (3'-chlorophenyl) -5-pyrazolone - 3 - carboxylic acid butylamide etc.



       The new dyes dye wool from acidic baths in yellow shades that: after chrome-plating turn into red shades, which can also be obtained directly after the single-bath chrome plating process. The chrome-plated colors have very good wet and light resistance.



  The subject of the present patent is a process for the preparation of a chromable monoazo dye, characterized in that diazotized 2-amino-4-di-isobutylphenol-6-sulfonic acid with 3-methyl-5-pyrazolone; coupling ..



  The new dye is a red powder, the solution of which is orange in water and yellow-orange in sulfuric acid. It dyes wool in yellow tones that turn red when treated with chromium saddles. Example: 30.1 parts of 4-diisobutylphenol by sulfonation, nitration and reduction represented 2-amino-4-diisobutylphenol-6-sulfonic acid are indirectly diazotized and the diazonium compound with 9,

  8 parts of 3-l-ethyl-5-pyrazolone coupled with alkaline soda. As soon as the dye formation is complete, the dye is worked up in the usual way. It dyes wool in yellow-tinged red tones with good cup and light resistance using the single bath or post-chrome plating process.
