Abstract
Procedimiento para la obtención de colorantes oxazínicos, de fórmula **fórmula** en la que R, R1 y R2 representan grupos alquilo, aralquilo o arilo, opcionalmente sustituidos, o, alternativamente R y R1 tomados junto con un átomo de nitrógeno forman un anillo, R3 es hidrógeno, alquilo o aralquilo, o alternativamente, R2 y R3 tomados conjuntamente forman un anillo con el átomo de nitrógeno, los anillos X e Y pueden estar sustituidos adicionalmente con grupos alquilo y Z- es un anión, caracterizado porque comprende nitrosar una amina de fórmula **fórmula** en un medio acuoso acídico y, sin aislar el compuesto nitroso, hacer reaccionar la suspensión acuosa de compuesto nitroso así formado con un m-aminofenol**fórmula** a un pH de 1,0 a 4,5Process 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, reacting the aqueous suspension of nitrous compound thus formed with an m-aminophenol ** formula ** at a pH of 1.0 to 4 ,5
