Abstract

Procedimiento para preparar nuevos colorantes azoicos principalmente de valor como colorantes reactivos para los materiales textiles celulósicos. Es bien conocido que los colorantes solubles en agua que permiten tonalidades que van del verde al azul en materiales textiles pueden obtenerse por copulación de dos moles de compuestos de diazonio de la serie de benceno o naftaleno con ácidos 1,8-aminonaftol sulfónicos. Colorantes que contienen radicales halógeno-s-triazina o halógeno pirimidina como resultado de los cuales los colorantes son capaces de reaccionar con materiales textiles de celulosa en presencia de álcali.
