Description
Patented Mar. 12, 1940 PATENT OFFICE PRQCESS FOR PltODUCING PRINTS AND DYEINGS WITH ESTER SALTS 0F LEUGO VAT DYESTUFFS Ernst Tschan, Basel, Switzerland, assignor to the firm Durand & Huguenin S. A., Basel, Switzerland No Drawing. Application October 25, 1937, Se-
rial 1936 5 Claims.
The method for printing and dyeing with ester salts of leuco vat dyestuffs consists in applying these bodies in the form of watery solutions, bringing the solutions onto the fibre and subjecting the same to an acid oxidation, whereby the vat dyestuff is regenerated in a very fine division and so that the dyeing is developed.
The color can be developed by means of special developing baths (see U. S.'A. Patent 1,575,958). The development can also be carried out by steaming with the aid of an appropriate oxidizing agent in the presence of a substance yielding acid in the heat (see U. S. A. Patent 1,747,107)
According to the process described in British Patent 356,577, aluminium chlorate, which acts at the same time as oxidizing and as acid yielding agent, and which enables the development of colors of leuco ester salts also without steaming, is used. To this effect, the goods are at first padded with a solution of tartaric acid and ammonium vanadate, and dried. Then they are printed with a printing color containing a leuco ester salt and aluminium chlorate. Finally, development is effected by simply hanging the goods at room temperature. I
It has now been found that this process can be simplified by printing or padding the goods with a color containing a leuco ester salt, ammonium chlorate and ammonium vanadate or ammonium chlorate, ammonium persulphate and ammonium vanadate, the latter being added as a catalyst. Ammonium persulphate is employed in addition to ammonium chlorate in cases where the ester salts of leuco vatdyestufis used are developed only with difficulty. Here also the development of the color is operated by simply hanging the goods at an ordinary or slightly raised temperature. But in this case, the pre-treatment of the fibre, that is to say the padding of the same with a solution of tartaric acid and ammonium vanadate before applying the printing color, is not necessary;
This new method, whereby the pre-treatment of the goods can be dispensed from, represents No. 170,991. In Germany October 26,
a real improvement, compared with the processes applied so far. I
The new process is especially suitable for cotton printing. tain neither copper, nor any other heavy metal salts, which might attack the doctor or lead to some other trouble. Besides, the colors have a goods stability, and the shades obtained in this way are well developed. I g
The new process may also be used forpadding, whereas the process applied hitherto was only suitable for printing purposes. y
The persulphuric acid and the chloric acid can be used in the form of any other soluble salt, Without influencing the effect, so long as the formation of the ammonium salts of such acids in the printing paste or in. the padding liquor is guaranteed (e. g. sodium chlorate and ammonium chloride).
