Abstract

Un procedimiento para la preparación de bases colorantes de las series nigrosina e indulina, con características aplicativas mejoradas, caracterizado porque el colorante azínico, esencialmente constituido por bases de nigrosina e indulina, se trata con anhídrido ftálico, conduciéndose el tratamiento preferentemente en seco, o "in situ" sobre el colorante azínico tal como proviene de la síntesis, a una temperatura comprendida entre 135º y 150ºC, y durante un periodo de tiempo preferentemente comprendido entre 2 y 4 horas.
