KARL
oF'j-nnssAU, GERMANY, ASSIGNOR .ro AcTIEN GEsELLscHArT NILIKFABRIKATI'ON, or BERLIN, GERMANY.
1,183,748. 1T0 Drawing.
To all whom it may concern i Be it known that I, KARL MARX, a sub- 3 ect of the Duke of Brunswick, residingat Dessau, Germany, my post-oflice a ddress;being Albrechtstrasse 16, Dessau, Germany,
;have invented certain new and useful Improvements in Processes for Dyeing Skins, Hairs, and the like, of which the following is a specification.
I have found that a series of derivatives.
of dialkylaminodiphenylamin of the general formula:
in which R means an alkyl group'and R I signifies a univalent substituent, such as NH N(CH l T(C '-I-I,,) OH or the like, or a suitable derivative of these bodies, are excellently fitted for dyeing skins, hairs andthe like. There are thus-obtained, generally speaking, gray tints which are fast to weather and storage; the sln'ns to be dyed can be previously mordanted or not. The
dyeing. operation itself may be performed as usual but withoutadding an alkaline substance.
The following example illustrates my in= vention; the parts are by weight: The skin to be dyed is washed for about an hour in water containing 10-20 grams of calcined sodium carbonate per liter, well rinsed and then dyed in a bath which contains per liter 3 grams of the 'hydrochlorid of para-dimethylamino-para-aminodiphenylamin and about 60 grams of hydrogen peroxid of about 3 percent. strength. Dyeing is continued for about 3 hours at ordinarytemperature with periodical handling. Thereupon the skin is rinsed, submitted to centrifugal action, the flesh side of the skin coated with an emulsion of common 'salt solution .and yolk of egg, and the skin then dried and cleaned. There is obtained a very beautiful greenish-gray which withstands very well the influence of the weather.
On skins mordanted with chromium, quite simllar tints are obtained, whereas on skms previously mordanted with iron or Specification of Letters Patent.
rnocnss FOR hymns sums, nnmsnrm THE LIKE.

- Application filed July 16, 1914. 1 Serial No. 851,428.
aluminum mordants there are obtained beautiful tints, more blue-gray.
It is obvious that my invention is not details given therein. For instance by dyeing non-mordanted skins in the prescribed manner with para-para-tetramethyldiaminodiphenylamin hydrochlorid there is ob tained a beautiful green-gray tint which also withstands very well the influence of the weather. On a chromium mordant a quite similar tint is obtained.
-In like manner by means of para-dimeth'ylaminopara oxydiphenylamin abeautiful neutral gray may be produced on non-mordanted skins, which islalso fast to weather. liketints are produced.
Having now described my invention and the manner in which it may be performed what I claim is,
1. The herein described oxidizing agent not giving rise to an alkaline reaction in a bath which contains a salt of a base of the general formula as follows? -un -R,
in which R represents an alkyl group and R signifies a univalent substituent.
2. The herein described process which (CH;; )zN \,-NH I R1 in which R signifies a univaTnt inorganic substituent.
On iron and aluminium mordants process which conslsts in dyeing sklns 1n the presence of an limited to-the foregoing example or to the 4.. The herein deseiibed rocess whichmy hand in presence of two subscribing witconsists in dyeing skms in t e presence of nesses.
