Abstract

L'invention porte sur un procédé de préparation de nouveaux composés de bisazo qui consiste à coupler un dérivé d'acide hydroxynaphthalène-3,6-dicarboxylique avec un composé possédant deux groupes diazo dans la molécule à un rapport molaire de 2:1. Ces composés présentent une excellente résistance à l'eau, aux produits chimiques, aux solvants et à la chaleur.
