Abstract

Procedure for the preparation of basic oxazine dyes of the general formula (1) wherein R1 signifies an alcohol group of 1 to 4 carbon atoms, R2 signifies a hydrogen atom or an alcoholic group of 1 to 4 carbon atoms, and X ⊖ means an anion, by nitrosation of a secondary amine of the general formula (2) **(See formula)** in which R1 has the aforementioned meanings, in aqueous solution in mineral acid, rearrangement of the nitrosamine obtained to form the corresponding para-nitroso-compound, and condensation thereof with a meta-aminophenol of the general formula (3) **(See formula)** in which R1 and R2 have the aforementioned meanings, characterized in that the aqueous suspension resulting from the mineral acid salt of said para-nitroso-rearranged compound is condensed, without intermediate isolation, with the meta-aminophenol of the general formula (3) quoted.
