Our present invention relates to dyeing preparations and their conversion to dyestuffs.

This application is a divisional application of our U. S. Patent No. 1,932,152,.

6 These dyeing preparations contain a hydrazine-sulfonate of the diarylamine series, corresponding to the probable general formula:

XNH-RNH NH SO: alkali metal wherein X means a naphthalene nucleus or a rad- I0 ical of the benzene series which may contain in the para-position to the NH-group a further -NHNHSOaalkali-metal group and R means a radical of the benzene series, and a combining component containing a hydroxy or 15 an O-alkali-metal group whereof the adjacent position is capable of attaching an aryl-azo group.

As combining components of the aforesaid kind may be named: 2-hydroxynaphthalene, its nuclear substitution products as, for instance, aroylamino-hydroxynaphthalenes, (2-hydroxy-naphthalene-3 -carbonyl) -amino-aryls (as described in U. S. Patents No.. 1,101,111 and No. 1,140,747), (6halogen-or G-arylamino-2-hydroxy-naphthalene-3-carbonyl-amino-aryls (see German Patent No. 396,519 and British Patent No. 330,349), derivatives of 1-hydroxy-naphthalene-4-carbo1;ylic acid (see U. S. Patent No. 1,453,660), as, for instance, l-hydroxy-naphthalene-4-phenyl-ketone; compounds containing an acidic methylene group capable of being combined with diazo-compounds, as, forinstance, pyrazolones and derivatives of p-ketonaldehyde, for instance, acetoacetyl-amino-aryls and di- (aceto-acetyl-amino) aryls (see U. S. Patents No. 1,594,864, No. 1,594,866, No. 1,594,867, No. 1,580,709, No. 1,634,090), dihydroxy-quinolines (see U. S. Patents No. 1,820,039, No. 1,846,073 and No. 1,846,074, British Patent No. 332,940), (2-hydroxy-carbazole-3-carbonyl) -amino-aryls,. (2-hydroxy-benzo-carbazole 3 carbonyl) -amino-aryls, (2-hydroxy-anthracene-3-carbonyl) -an iino-aryls.

These dyeing preparations yield, when applied in an alkaline medium to fibers, by steaming 15 only, insoluble azo-dvestuffs on the fibers.

'Such applying to the fibers consists in dyeing according to the one-bath-method or in printing. The dyebath or the printing paste or also the powderous dyeing preparations themselves 30 are advantageously mixed with dyeing assiste ants having wetting, emulsifying or solvent prop erties, or also with the additional agents customary in using nitrosamine-printing colors, as, for instance, chromate. Furthermore, sulfur is 6 advantageously added to the printing paste.

Thereby, in some cases, the quickness and the evenness of the dyestufl formation is favorably influenced.
