Abstract

Procedimiento para preparar dispersiones de sustancias colorantes, particularmente de pigmentos, caracterizado porque comprende hacer reaccionar por condensación, a temperaturas entre 50 y 160ºC, compuestos aromáticos conteniendo grupos OH fenólicos con formaldehido y aminas que contienen un grupo NH capaz de reaccionar con formaldehido, para obtener productos de oxalquilación hidrosolubles; los cuales en una segunda etapa, se combinan con las sustancias colorantes insolubles en agua.
