Abstract

Procedimiento para la preparación de azocolorantes que contienen cobalto, los cuales incluyen un átomo de cobalto en enlace complejo con dos moléculas de diferentes monocazocolorantes, caracterizado porque se hace reaccionar medios que ceden cobalto con mezclas de un colorante o-oxi-o''-aminomonoazoico libre de grupos de poder hidrodisolvente y un colorante o, o''-dioximonoazoico libre de grupos carboxilo y de grupos de ácido sulfónico, el cual presenta como grupo de poder hidrosolvente a lo menos un grupo de sulfonamida o grupo sulfonilo.
