Abstract: of the disclosure: Valuable pigments are obtained by diazotizing 1-aminoben-zene-2-(carboxylic acid methyl or ethyl ester)-5-(2',3'-dichlo-ro-anilide) and coupling it onto 1-(2'-hydroxy-3'-naphthoylami-no)-4-acetamino-benzene. These pigments show a high tinctorial strength, a pure shade, a high fastness to migration, especially to overlacquerlng, to light and weathering and a high heat stability.
