Description
Patented Sept. 17, 1935 UNITED STATES- PATE. NT. OFFICE AZODYESTUFFS INSOLUBLE 11v WATER, AND v FIBERS DYED THEREWITH Werner Zerweck and Karl Schiitz, Frankfort-onthe-Main-Fechenheim, Germany, assignors to 7 77 General Aniline Works, Inc., New York, N. Y.,
a corporation of Delaware No Drawing. Application May 15, 1934, Serial 7 No. 725,820. In Germany May 23, 1933 8 Claims. (01. 260-95) 7 The present invention relates to new azodyestuffs insoluble in water more particularly to such corresponding to the general formula (wherein R1 means an aryl or aralkyl radical and R2 a combining component of-the group consisting of arylamides of acyl-acetic acids and orthohydroxy-aryl-carboxylic acids).
The dyestuffs may be prepared by combining in substance or on the fiber or on a substratum a 5 diazocompound of an amine 30.; Lasample 1 50 grams of cotton yarn are treated for half an hour with 1 liter of the following impregnating bath (a) squeezed or centrifugated; thewet ma-.
terial is then dyed in the developing bath (1)). Thereupon it is rinsed, soaped at thejboil and dried.
(a) Impregnating bath: V 7 grams of (2'-hydroxy-3'-naphthoylamino.),-
10 cc. of Turkey red oil of 50% strength and 10.5 cc. of caustic soda solution of 34 B, T0 the solution 2.7 cc. of formaldehyde of 30% strength are added and the Whole'is then made up'with cold water-to- 1liter."'
(b) Developing bath:
sulfone are diazotized with cc. of hydrochloric acid normal and 5 cc. of a normal sodium nitrate solution. After the addition of cc. of glacial acetic acid the hydrochloric acid 5 is neutralized by means of a solution of sodium acetate. Then i r V 30 grams of sodium chloride are added and the whole is made up with Water to 1 liter.
A vivid golden-orange dyeing of remarkable fastness qualities is obtained.
' Ewmr 2 Into an aqueous suspension of 26.3'grams of 2'- hydroxy-3'-naphthoyl-amino-benzene, prepared by. dissolving ,the, said arylide in an alcoholic caustic soda solution, diluting with Water and neutralizing with acetic acid, a diazo solution, prepared in the usual manner from 26.1 grams of 4-tolyl-2-amino benzyl-sulfone, is allowed to run in. The bright scarlet-red dyestuif separates in the form of flakes. When coupling is finished it is filtered with suction andwashed until neutral.
In the same manner similar clear yellowish orange shades may be obtained according to one of the usual printing methods.
The following table shows the shades of some 4 1 benzene are dissolved at boiling, temperafurther dyestuffs obtained according to the pres- 40 ture with 1 cut process: i p

Since an object of the present invention is to 3. Azodyestuff of the formula: 30 provide dyestuffs of good fastness properties, 01 which dyestuffs are insoluble in water and alkalies, it is to be understood that the benzene nuclei of CFOSOFOH the general formulae appearing in the appended claims do not contain any substituents which are t 35 known to render organic compounds soluble in water or alkalies and to tend to depreciate the fastness of the dyestuffs to alkalies. Substituents of this kind are, for instance, the sulfonic acid, the carboxylic acid and the hydroxy group.
