Abstract
Un procedimiento para preparar una solución colorante de diazo-urea concentrada y estable, caracterizado porque se hace reaccionar fosgeno con una solución acuosa de una sal alcanolamínica de un compuesto aminoazoico de la fórmula E-A-N=N-B-Nh2, solo o mezclado con 50% en moles, a lo sumo, de un compuesto aminoazoico de la fórmula E''-A''-N=N-B'' -NH2, a temperatura de 35º C a 60º C, mientras se mantiene el pH de la solución reaccional en un intervalo de 5,0 a 8,5 por medio de una base de litio, sola o en combinación con 35% a lo sumo de trietanolamina, N-metildietanolamina o N,N-dimetietanolamina, representando en el compuesto aminoazoico **Formula** cada uno independientemente, un grupo naftílénico o fenilénico, insubstituido salvo por E y E'' o ulteriormente substituido por uno o dos grupos de los cuales uno se toma del conjunto constituido por hidroxilo, nitro, ciano, trifluorometilo, carboxilo y SO3M (donde M es K, Ma, Li o H) y/o uno o dos se toman del conjunto constituido por alquílo inferior, alcoxilo inferior, hidroxilo-alquilo inferior, hidroxilo-alcoxilo inferior y halógeno.
