- OBTHOOXYAZO DYESTUFF.
No Drawing.
To all whom it may concern:
Be it known that we, EUGEN ANDERWFJRT, chemist, a citizen of the Swiss Republic, HERMANN FRrrzscHE, chemist, a citizen of the Swiss Republic, and HEINRICH ScHoBEL, chemist, a citizen of the Swiss Republic, all residents of Basel, Switzerland, have invented a Process for Producing on the Fibers New Copper Compounds of Substantive Orthooxyazo Dyestufls, of which the following is a full, clear, and exact specification.
In our application for a U. S. Letters Patent, Ser. No. 59580, filed November 4, 1915,-
. we have described the production of new 1917, subsequently On the fiber with copper copper compounds of substantive orthooxyazo dyestuffs, which can be fixed like the known substantive dyestuffs without more dant on the various textile fibers, yielding hereby tints of excellent fastness to light, washing and alkali.
We have now found that the copper compounds of the same orthooxyazo dyestufi's can also be produced on the fibers, by treating for instance the dyeings obtained directly on the fiber with the substantlve orthooxyazo dyestuffs described in the applications for United States Letters Patent Ser. No. 144244, filed January 24, 1917 (divisional application of Ser. No. 54403),'Ser. No. 144243, fi led January 24, 1917 (divisional application of Ser. No. 54403), Ser. No. 54513, filed October 7, 1915, Ser. No. 1647 95', filed April 26, 1917 (divisional application of Ser. No. 545-13) and in the U. S. Letters Patent No. 1210751, dated January salts or by dyeing the fiber with the said orthooxyazo dyestufls in a bath containing copper salts.
The new process is illustrated by thefollowing examples:
Example 1 The monoazo dyestufi' prepared from orthodiazoparacresolfonic acid and is dyed in the manner usually employed for substantive dyestuifs with 5 to 40% cryst allized sodium sulfate and 1 to 5% sodlum'car- Specification of Letters Pateut.

The resulting tint is identical with that obtained by dyeing with the copper. compound of the same dyestufi' without subsequent treatment. 7
Example 2: The monoazo dyestufi resultmg from 4: 2: l-nitrodiazophenol and is dyed in the manner employed for substantlve dyestuffs in a bath containing 1% crystallized copper sulfate, 20% sodium sulfate and 2% calcined soda,
the goods being introduced into this bath at a temperature of 40-50 C. and the bath heated to ebullition for to 1 hour. Hereafter the goods are rinsed and dried. The obtained dyeing is identical with that obtained with the copper salt of the same monoazo dyestuff.
-In an analogous manner can be produced on the fiber the variousother copper com- 1 pounds of orthooxyazo dyestufis described in our application for aU. S. Letters Patent Serial No. 59580, filed November 4, 1915.
dyestufi derived from a 2: 5:7-aminonaphthol sulfonic compound.
2. The described process for producing I fast tints; on animal or vegetable goods,
which consists in first dyeing the goods in a 1915, in the presence of two subscribing Witbath formed by a solution of a substantive messes.
