Method for the preparation of leuco compounds from the according to the method of
U.S. Patent No. 55688.
Patent No. 55688 describes a process for the preparation of oxazine dyes which are obtained from pyrogallol derivatives and p-nitrosophenols or quinone chlorimides,
EMI1.1
Dyes treated with salts of sulphurous acid. This is all the more surprising since the reduction with free sulphurous acid only gives Leulio bodies of the same shade as the products obtainable with other common reducing agents.
In British Patent No. 11556 A.D. 18! J3 and in the American patent
EMI1.2
wise from p-nitrosophenols accordingly, the hydroxyl group of the nitrosophenol is not used for ring formation, but as such is contained unchanged in the resulting dye or its leuco compound. In the first case is therefore
EMI1.3
Nuclei hydroxyl groups.
Example 1.
30 parts of the dye from gallamic acid and nitrosophenol or the equivalent
EMI1.4
contains more, one sucks off; the product can be used directly as a paste for printing purposes. The shade of the chrome lacquer is a reddish Corinth and significantly more brown than that available with the original material. The Chromalck is also characterized by its resistance to chlorine and soap.
Example 2.
