Abstract
Procedure for obtaining oxazine dyes, of formula ** formula ** in which R, R1 and R2 represent optionally substituted alkyl, aralkyl or aryl groups, or alternatively R and R1 taken together with a nitrogen atom form a ring, R3 is hydrogen, alkyl or aralkyl, or alternatively, R2 and R3 taken together form a ring with the nitrogen atom, the X and Y rings can be additionally substituted with alkyl groups and Z- is an anion, characterized in that it comprises nitrosating a amine of formula ** formula ** in an acidic aqueous medium and, without isolating the nitrous compound, react the aqueous suspension of nitrous compound thus formed with an m-aminophenol ** formula ** at a pH of 1.0 to 4,5 (Machine-translation by Google Translate, not legally binding)
