  Process for the production of real, color-etched vat dye dyes.



   For a long time vat dyes have been used as colored etching on dyeings made with azo inks. With these articles, however, the colored base is of course much less authentic than the colored etchings used for this purpose, and in addition, vat dyes in this article have the property of forming aureoles very easily. Vat dyes are also used as colored etching on indigo.



  In this case, too, the colored floor is not as real as the colored etchings printed on it.



   It has now been found that you can produce an etching article unsurpassed in the authenticity, if you produce dyeings with such vat dyes that by reducing agents, such as. B. formaldehyde sulfoxylates with the addition of Leukotrope W conc. are destroyed and used as colored etching vat dyes that withstand these etching agents sufficiently. It is essential to use only so much formaldehyde sulfoxylate with the addition of Leukotrope W conc. to be used as necessary

 to attack. The colored etchings with vat colors in this article also have the advantage that they do not form aureoles.

Claims (1)

EMI2.4 draws that vat dyes are used for the colorations to be etched, which are destroyed with reducing agents with the addition of weak alkalis and larger amounts of lime salt of the disulfonic acid formed by sulfunera of dimethylphenylbenzylammonium chloride, while vat dyes are used for the colored etchings which these etchants sufficiently resist. ;
