Specification of Letters Patent. Application fil ed December 7, 19111 serial-no. 664,450.
Patented Oct. 15, EH2.
'Be it known that I, CARL PILZ, a subject of the Austro-Hungarian Emperor, residing at Liesing, near Vienna, Austria-Hungary,
'have invented-certain new and useful Improvements in Processes of Producing Fast; Brown Resists in Vegetable Fibers, of which the following is a specification.
The'surp'rising observation has been made that easily oxidized aromatic amlns when printed on undeveloped anilinblack padding, prevent the oxidation of the anilin to 'black, and are themselves developed to fast brown dyes. If,' for example, thecotton material is padded in the usual manner with anilin salt, potassium 'ferrocyanid,' sodiumchlorate, 'and oso forth, dried, and printed on .with an aromatic amin, for example, m-aminophenol, the subsequent steaming in a Mather-Flatt will not produce black at the printed places, but an olive brown, while the ground appears black. I 1
' The resistive efiectoof the easily oxidized amins, aminophenols, diamins, triamins, and.
so forth, is so strong that even when printing a mixture of anilin with one of these aminophenols, and so forth-with the necessary oxidizing agents, the anilin remains unoxidized and only the brown color results from the oxidized aminophenol. I The easily oxidizabl'e amins', diamin's, triamins, 'aminophenols, diaminophenols, triamins of the benzohseri'es and naphthalene series may be utilized. These a-mi'ns areall embraced in the: generic class of easily oxidizable "aromatic amins. Some ofjthe'se'. amins give a great va rietyf -of shades, for ex-' ample m-ami'nophenol gives an olive brown,
o-aminophenol a red brown, m-phenylene 'diamin and m-toluyl'ene' diar'nin an olive and o-amidocresol a yellow brown; others how- 'by steammg. 1 4
2. The process of producing fast brown ever give less striking shades, such as p-phenylene diamin, benzidin, and so forth give very dark shades of brown.
It isof great importance that these brown resists may easily be reserved with the white and colored resists used habitually for aniiin -.black.' Thus, a large number of new combinations can be obtalned by means of the new process which could not be obtained till DOW.
my process: The material prepared in the usual manner-With anilin black padding and then dried, is printed .on with a print color, which apart from the thickening, without other resist, contains for every liter 40430 g.

resists on vegetable fibers which comprises padding such materiai with anilin black and printing on such material an easily oxidize able aminophenoL-and developing thepaddedand printed material by steaming.
In testimony whereof I have affixed my signature in presence of two witnesses.
